3 Side Channel Pumps Self-priming, segmental type with verly low NPSH CEH Sizes , 1202/5 6108/5, 1202/7 6107/7 Technical data Capacity: Delivery head: Speed: max. 35 m³/h max. 354 m max /min Temperature: max. 120 C max. 180 C for high temperature design (higher temperatures upon request) Casing pressure: PN 40 Shaft sealing: Stuffing box or mechanical seal Flange connections: DIN 2501 / PN 40 Direction of rotation: anti-clockwise (when seen from the drive end) Application The SIHI CEH pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. The CEH pumps are used for problem-free pumping of clean liquids at unfavourable suction side conditions. They are also very suitable for positive suction heads below 0.5m. The different material possibilities with uniform dimensions and performance characteristics as well as the standard exchangeable components, make the CEH particularly recommendable for applications in the pharmaceutical, chemical or petrochemical market as well as in the plastic or oil industry. Because of its low NPSH and positive suction head the CEH is very suitable for the pumping of liquefied gasses and liquids under vapour pressure like condensate, refrigerant, boiler feed water or LPG. The pumps of the CEH /7 series have a retaining stage to avoid the dry running by controlling the liquid level in the pump. This design is especially developed for the handling of liquids under vapour pressure or when pumping from underground tanks. The series CEH /5 are used for bottom off-loading of liquids under vapour pressure. Design Pumps of the series CEH have a segmental type construction with open vane wheel impellers. The construction of the CEH pump is a so-called centrifugal combined system. This combination pump is suited with a centrifugal stage in serial connection before the side channel stages to obtain a more favourable NPSH. The program comprises 6 sizes each with 1-8 stages. The existing material design allows an optimum rating for the respectively desired performance range and the pumping medium. Pumps of the series CEH /7 are equal to the CEH series but equipped with a retaining stage. This program comprises 6 sizes with 2-7 stages. The series CEH /5 have also 6 sizes but with 2-8 stages. The applied hydraulic components are from our Modular Side Channel system (interchangeability of parts). Construction Casing pressure Maximum 40 bar from -40 C up to +120 C. Maximum 32 bar from +120 C up to +180 C. Pressure stages for temperature as per DIN EN Please observe Technical rules and safety regulations. Casing pressure = inlet pressure + delivery head at minimum pump capacity. Position of branches Axial suction branch, discharge branch points radially upwards. Flanges The flanges correspond to DIN EN / PN 40. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. Bearing One grease lubricated ball bearing according to DIN 625 and one liquid surrounded sleeve bearing (design A). The ball bearing is greased for life. Direction of rotation Anti-clockwise, when looking from the drive end. Shaft sealing The shaft can be sealed by a stuffing box or a mechanical seal conform DIN EN The shaft sealing is also available in a design suitable for heating or cooling of the stuffing box or the mechanical seal. Double mechanical seal (back-to-back as well as tandem) or a quench design with throttle bush are available upon request. The CEH can also be supplied with a magnetic coupling (for information see the separate catalogue). PUMP TECHNOLOGY CEH E 05/2015

This type of construction causes that the remaining liquid quantity is smaller than that which remains in pumps with radial branches. Thus the gas handling capacity is lower. In order to maintain the specific priming capability, it is necessary to equip the pump with a retaining stage or install the suction line with a swanneck at sufficient distance from the suction branch.

Reduced output by increased stage clearance The standard stage clearance is: Size 1200, 3100 and 3600 Size 4100, 5100 and ,13 till 6 mm +0,18 till +0,21 mm The increase of the stage clearance results in losses caused by the back flow, which influence the delivery head and strongly affect the self-priming capability. From the above diagrams you may learn the degree of losses in delivery head by multiplication of delivery head at standard stage clearance with the factor F. Hereby the power absorption is changed slightly. When the stage clearance is increase, the self-priming capability is no longer assured.

High temperature Execution For the selection of pumps, especially at temperatures above 120 degrees Celsius, the maximum sustainable casing pressure is an important limit (see the enclosed curve). For hot water also the sliding properties are very bad. So a careful selection for material and mechanical seals is necessary. In the standard delivery program there are several executions for high temperature; Execution Sealing Material Temp. (max) Included 1) Cooled stuffing box 501 1A 1B 140 C Cup springs, cooled stuffing box casing Cooled mechanical seal 3) AS3 ASK ASV 1A 1B 4B Example: CEHA 3104 AA AS3 1A C 2) Cup springs, cooled mechanical seal casing, GNZ mechanical seal and special bearing bush for high temperatures Remarks: 1) The by-pass (pos 70.10) that was still used in the old delivery program for the CEH has now been removed. 2) The GNZ can be used uncooled up to 140 C. 3) For applications with a temperatures 120 C the standard pumps will always be supplied with cup springs, a cooled mechanical seal or stuffing box and the special high temperature bearing bush (material 252 or Carbon Antimony).

Repair hints The following repair hints are to be observed: Intermediate piece, item 10.90, 11.40, The sliding surfaces can be re- turned up to 0,5 mm. Doing so the plan parallelism must be kept. Max. admissible peak- to- valley height is R t = 6 µm, deviation of the plan parallelism 10 µm. The sealing surface of the intermediate piece is to be re- turned, in order not to change the clearance of the vane wheel impellers. Up to construction size 3600 the depth +0,160 +0,130 and from size ,210 +0,180 has to be larger than the width of the vane wheel impeller. Is this recommended to re- turn not more than indispensably necessary. In case of an increased number of stages and utilization of the total turn- out dimension it might be better to install a combination of new and old stages, in order to avoid difficulties in assembling and performance (shaft length). Vane wheel impeller, item From a reworking on the vane-wheel impeller should be refrained, as a reduced output might arise which cannot be calculated and thus the interchange ability is not more ensured.

The AEH is a Side Channel pump as per DIN EN 734 and operates at a low noise level. The AEH pumps were especially developed for difficult applications in all industry sectors and are thus applied when pure, turbid or aggressive media have to be pumped under difficult conditions without any problems. The different material possibilities with uniform dimensions and performance characteristics as well as the standard exchangeable components, make the AEH particularly recommendable as universal pump for all possible pumping problems. This results in a wide application range in many sectors such as: Chemical Industry Petro-chemical Industry Pharmaceutical Industry OEM Oil Industry Food Industry Design Pumps of the series AEH have a segmental type construction with open vane wheel impellers. The pumps is available in a normal industrial design with one liquid surrounded slide bearing and one ball bearing or in a heavyduty construction with a double ball bearing design. The program comprises 6 sizes each with 1-8 stages. The existing material design allows an optimum rating for the respectively desired performance range and the pumping medium. The applied hydraulic components are from our Modular Side Channel system (interchangeability of parts). Construction Casing pressure Maximum 40 bar from -40 C up to +120 C. Maximum 32 bar from +120 C up to +180 C. Pressure stages for temperature as per DIN EN Please observe Technical rules and safety regulations. Casing pressure = inlet pressure + delivery head at minimum pump capacity Position of branches Suction and discharge branch point radially upwards. Flanges The flanges correspond to DIN EN / PN 40. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. Bearing Either by a ball bearing and a liquid surrounded sleeve bearing (design A) or by two ball bearings (design B). The ball bearings are according to DIN 625 and greased for life. Direction of rotation Clockwise, when looking at the pump from the drive end. Anti-clockwise is possible. Shaft sealing The shaft can be sealed by a stuffing box or a mechanical seal conform DIN EN The shaft sealing is also available in a design suitable for heating or cooling of the stuffing box or the mechanical seal. Double mechanical seal (back-to-back as well as tandem) or a quench design with throttle bush are available upon request.

Reduced output by increased stage clearance AEH 1200,3100,3600 AEH 4100,5100,6100 The standard stage clearance is: Size 1200, 3100 and 3600 Size 4100, 5100 and ,13 till +0,16 mm +0,18 till +0,21 mm The increase of the stage clearance results in losses caused by the back flow, which influence the delivery head and strongly affect the self-priming capability. From the above diagrams you may learn the degree of losses in delivery head by multiplication of delivery head at standard stage clearance with the factor F. Hereby the power absorption is changed slightly. When the stage clearance is increase, the self-priming capability is no longer assured.

Repair hints The following repair hints are to be observed: Intermediate piece, item 10.90, 11.40, The sliding surfaces can be re- turned up to 0,5 mm. Doing so the plan parallelism must be kept. Max. admissible peak- to- valley height is R t = 6 µm, deviation of the plan parallelism 10 µm. The sealing surface of the intermediate piece is to be re- turned, in order not to change the clearance of the vane wheel impellers. Up to construction size 3600 the depth +0,160 +0,130 and from size ,210 +0,180 has to be larger than the width of the vane wheel impeller. Is this recommended to re- turn not more than indispensably necessary. In case of an increased number of stages and utilization of the total turn- out dimension it might be better to install a combination of new and old stages, in order to avoid difficulties in assembling and performance (shaft length). Vane wheel impeller, item From a reworking on the vane wheel impeller should be refrained, as a reduced output might arise which cannot be calculated and thus the interchange ability is not more ensured.

83 Sterling Fluid Systems (France) S.A. Bearing bushes, item 0241, 0242, and following The bearing bushes are glued in with special glue. Before glueing them in, the corresponding places are to be cleaned carefully from probable residues and oils. Radial seal ring, item When fitting the radial seal ring, the sealing lip must be in correct position; it has to point outwardly in order to avoid excessive grease and to avoid the penetration of dirt. Gland packing rings, item When fitting them, their correct number and the position of the lantern ring must be observed, in order not to cover a drain or hydraulic bore which may exist. Mechanical seal, item 43.30, Check the O- rings for usability, replace worn out rings. Re- lap sliding surfaces, if necessary and check carefully for hairline cracks. When mounting the mechanical seal observe the sense of winding of the spring and the installation dimensions! If the old shaft is used, the seat must be free of residues. If necessary it must be relapped, too.

105 Side Channel Pumps Self-priming, segmental type AKH Sizes TECHNICAL DATA Capacity: Head: Speed: max. 35 m³/h max. 144 m max rpm Temperature: max. 120 C Casing pressure: PN 16 Shaft sealing: Stuffing box, mechanical seal Flange connections: DIN 2501 / PN 16 Direction of rotation: Clockwise (when viewed from the drive end) APPLICATION The SIHI AKH pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. The AKH is suitable for trouble free handling of clean or turbid liquids without any abrasive particles. The performance curve steepness admits a precise regulation of the pressure with a small change in capacity. The AKH pump has been developed for a broad range of medium duty applications in: Chemical industry, Petro-Chemical industry, Oil industry, Machinery and automobile industry, Food industry, Building trades, Plastic and rubber industry, Surface treatment, Ship yards. DESIGN Pumps of the series AKH have a segmental type construction with open vane wheel impellers. The pump construction is either with one liquid surrounded slide bearing and one ball bearing or in a more industrial construction by using a double ball bearing design. The program comprises 6 sizes with up to 4 stages (an extension with 5 or 6 stages is possible for certain sizes). The performance curves of the AKH are identical for all the material designs. CONSTRUCTION Casing pressur Maximal 16 bar from -40 C to C. Please observe Technical rules and safety regulations. Casing pressure = inlet pressure + delivery head at minimum pump capacity. Position of branches Suction and discharge branch point radially upwards. Flanges The flanges correspond to DIN EN / PN 16. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. Bearing Either by one grease lubricated ball bearing and one liquid surrounded sleeve bearing (design A) or by two grease lubricated ball bearings (design B). The ball bearings are according to DIN 625. The first grease filling is done in the factory. Direction of rotation Clockwise, when looking at the pump from the drive end. Anti-clockwise is possible. Shaft sealing The shaft can be sealed by either a stuffing box or a standard mechanical seal. The applied hydraulic components are from our Modular Side Channel system (interchangeability of parts).

Reduced output by increased stage clearance The standard stage clearance is: Size 1100, 1200, 3100 and 3600 Size 4100, 5100 and ,13 till +0,16 mm +0,18 till +0,21 mm The increased of the stage clearance results in losses caused by the back flow, which influence the delivery head and strongly affect the self-priming capability. From the above diagrams you may learn degree of losses in delivery head by multiplication of delivery head at standard stage clearance with the factor F. Hereby the power absorption is changed slightly. When the stage clearance is increased, the self-priming capability is not longer assured.

139 Sterling Fluid Systems (France) S.A. 13. Repair hints The following repair hints are to be observed: Intermediate piece, item 10,11,12 The sliding surfaces can be re- turned up to 0,5 mm. Doing so the plan parallelism must be kept. Max. admissible peak- to- valley height is R t = 6 µ, deviation of the plan parallelism 10 µm. The sealing surface of the intermediate piece is to be re- turned, in order not to change the clearance of the vane wheel impellers. Up to construction size 3600 the depth +0,160 +0,130 and from size ,210 +0,180 has to be larger than the width of the vane wheel impeller. Is this recommended to return not more than indispensably necessary. In case of an increased number of stages and utilization of the total turn- out dimension it might be better to install a combination of new and old stages, in order to avoid difficulties in assembling and performance (shaft length). Vane wheel impeller, item 30 From a reworking on the vane-wheel impeller should be refrained, as a reduced output might arise which cannot be calculated and thus the interchange ability is not more ensured. Bearing bushes, item 0241, 0242, and following The bearing bushes are glued in with special glue. Before glueing them in, the corresponding places are to be cleaned carefully from probable residues and oils. Radial seal ring, item 426 When fitting the radial seal ring, the sealing lip must be in correct position; it has to point outwards in order to avoid excessive grease and to avoid the penetration of dirt. Gland packing rings, item 400 When fitting them, their correct number and the position of the lantern ring must be observed, in order not to cover a drain or hydraulic bore which may exist.

140 Sterling Fluid Systems (France) S.A. Mechanical seal, item 500, 600 Check the O- rings for usability, replace worn out rings. Re- lap sliding surfaces, if necessary and check carefully for hairline cracks. When mounting the mechanical seal observe the sense of winding of the spring and the installation dimensions! If the old shaft is used, the seat must be free of residues. If necessary it must be relapped too. 14. Permissible loads on branches and permissible moments If different directed forces exist at the same time, the components of the resultants of these forces may not exceed the permissible values of each direction of force. The pump feet must be levelled and equally tightened to the base plate. If these requirements are not met, tightness and durability cannot be guaranteed.

183 Sterling Fluid Systems (France) S.A. 11. Repair hints The following repair hints are to be observed: Intermediate piece, item 10,11,12 The sliding surfaces can be re- turned up to 0,5 mm. Doing so the plan parallelism must be kept. Max. admissible peak- to- valley height is R t = 6, deviation of the plan parallelism 10 m. The sealing surface of the intermediate piece is to be re- turned, in order not to change the clearance of the vane wheel impellers. Up to construction size 3600 the depth +0,160 mm +0,130 mm has to be larger than the width of the vane wheel impeller. Is this recommended to return not more than indispensably necessary. In case of an increased number of stages and utilization of the total turn- out dimension it might be better to install a combination of new and old stages, in order to avoid difficulties in assembling and performance (shaft length). Vane wheel impeller, item 30 From a reworking on the vane wheel impeller should be refrained, as a reduced output might arise which cannot be calculated and thus the interchange ability is not more ensured. Bearing bushes, item 0241, 0242, and following The bearing bushes are glued in with special glue. Before glueing them in, the corresponding places are to be cleaned carefully from probable residues and oils. Gland packing rings, item 400 When fitting them, their correct number and the position of the lantern ring must be observed, in order not to cover a drain or hydraulic bore which may exist.

189 SIHI prime - Side Channel Pumps Self-priming, segmental type with very low NPSH CEH-X TECHICAL DATA Capacity: Delivery head: Speed: from 0.4 up to 7.5 m³/h from 10 up to 322 m 1450 rpm (max rpm) Temperature: max. 120 C max. 180 C for high temperature design (higher temperatures on request) Casing pressure: PN 40 Shaft sealing: mechanical seal Flange connections: DIN 2501 / PN 40 Direction of rotation: Protection classification: anti-clockwise (when seen from the drive end) Ex II2 Gc T1-T5 APPLICATION The Sterling SIHI CEH-X pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. The CEH-X pumps are used for problem-free pumping of clean liquids at unfavourable suction side conditions. They are also very suitable for positive suction heads below 0.5 m. Different material possibilities with uniform dimensions and performance characteristics as well as the standard exchangeable components are used for the construction. The CEH-X pumps are particularly recommendable for applications in the pharmaceutical, chemical or petrochemical market as well as in the plastic or oil industry. Because of its low NPSH and positive suction head the CEH-X is very suitable for the pumping of liquefied gases and liquids under vapour pressure like condensate, refrigerant, boiler feed or LPG. The CEH-X pumps have a retaining stage, combined with the low NPSH stage, to avoid the dry running by controlling the liquid level in the pump. This design is especially developed for the handling of liquids under vapour pressure or when pumping from underground tanks. The CEH-X pumps are used for bottom off-loading of liquids under vapour pressure. DESIGN The pumps of the SIHI prime range are side channel pumps having segmental type construction. The construction of the CEH-X pump is a centrifugal combined system. This combination pump is suited with a centrifugal stage in serial connection before the side channel stages to obtain a more favourable NPSH. The program comprises, currently, 3 sizes (1200, 3100 and 3600) each with 1-8 stages. The existing material design allows an optimum rating for the respectively desired performance range and the pumping medium. The applied hydraulic components are from our modular side channel system (interchangeability of parts). CONSTRUCTION Casing pressure Maximum 40 bar from -40 C up to +120 C. Maximum 32 bar from +120 C up to +180 C. Pressure stages for temperature as per DIN EN Please observe Technical rules and safety regulations: Casing pressure = inlet pressure + delivery head at minimum pump capacity. Position of branches Axial suction branch, discharge branch points radially upwards. Flanges Flanges in accordance with DIN EN / PN 40. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. Bearing One grease lubricated, greased for life, ball bearing according to DIN 625 and one liquid surrounded sleeve bearing. Rotation direction Anti-clockwise, when looking from the drive end. Shaft sealing The shaft is sealed by a mechanical seal according to DIN EN 12756, with quench connection. The shaft sealing is also available in a design suitable for heating or cooling of the mechanical seal and a double mechanical seal (back-to-back as well as tandem) design is possible on request.

192 CEH-X Operating principle The CEH-X pump is a combined system side channel pump. It is suited with a low NPSH centrifugal impeller (1) placed before the side channel stages. This NPSH inducer stage delivers enough pressure to overcome the entrance pressure loss of the first side channel stage or the required NPSH. 1 A side channel stage consists of: A suction intermediate (2), A discharge intermediate including the side channel (3), A vane wheel impeller located between the 2 intermediates (4) The fluid entrance goes through the suction hole (5). The turning of the vane wheel impeller creates an under pressure at the beginning of the side channel and the liquid (with or without gas) is drawn in. The pressure generating is obtained by the repetitive re-entering of the liquid in the side channel (6). The liquid goes then to the next stage through the discharge hole (7). The air displacement channel (8) provokes a positive displacement effect so the gas remaining at the root of the vane wheel impeller is forced out through the gas slot (9) A side channel pump can de-aerate and degas the suction line by itself and is thus very suitable for suction lift operation. A side channel pump can handle large quantities of (entrained) gas. Mixtures up to a gas share of 50% are possible. The ability for self-priming and the handling of large amounts of (entrained) gas will guarantee continuous operation even in case of evaporation and therefore contribute to a higher level of safety in industrial processes. To avoid cavitation the distance between the liquid level and the entrance at the suction side of the pump is restricted. This distance is related to the NPSH or Net Positive Suction Head. The NPSH for CEH-X pumps is very low due to its special construction. The axial and large diameter entrance leads to less flow disturbance and lower friction losses. Together with the low NPSH of the centrifugal impeller the CEH-X can handle a positive suction head of less than 0.5 m. This makes the CEH-X very suitable for pumping liquids near their boiling point at reasonable economic expenses and the low NPSH guarantees also full output capacity because of operation without cavitation 4

The standard design of internal retaining stage is keeping the required service liquid inside the pump which is ensuring the self priming capability. During longer stand still phases a part of service liquid can get lost through the gab of sleeve bearing. A special sealing ring can protect for undesirable losses of service liquid. The direction of sealing should be in flow direction of the pump. This saves a good lubrication sleeve bearing during operating. Assembling position!

223 AEH-X Operating principle The AEH-X pump is a side channel system, self priming, and segmental type. 1 A side channel stage consists of: A suction intermediate part (1), A discharge intermediate part including the side channel (2), A vane wheel impeller located between the 2 intermediate parts (3) The fluid entrance goes through the suction hole (4). The turning of the vane wheel impeller creates an under pressure at the beginning of the side channel and the liquid (with or without gas) is drawn in. The pressure generating is obtained by the repetitive re-entering of the liquid in the side channel (5). The liquid goes then to the next stage through the discharge hole (6). The air displacement channel (7) provokes a positive displacement effect so the gas remaining at the root of the vane wheel impeller is forced out through the gas slot (8) A side channel pump can de-aerate and degas the suction line by itself and is thus very suitable for suction lift operation. A side channel pump can handle large quantities of (entrained) gas. Mixtures up to a gas share of 50% are possible. The ability for self-priming and the handling of large amounts of (entrained) gas will guarantee continuous operation even in case of evaporation and therefore contribute to a higher level of safety in industrial processes. To avoid cavitation the distance between the liquid level and the entrance at the suction side of the pump is restricted. This distance is related to the NPSH or Net Positive Suction Head. This makes the AEH-X very suitable for pumping liquids near their boiling point at reasonable economic expenses. 4

Before glueing in them, the corresponding places are to be cleaned carefully from probable residues and oils. Radial seal ring, item When fitting the radial seal ring, the sealing lip must be in correct position; it has to point outwardly in order to avoid excessive grease and to avoid the penetration of dirt. Mechanical seal, item 43.30, Check the O- rings for usability, replace worn out rings. Re- lap sliding surfaces, if necessary and check carefully for hairline cracks. When mounting the mechanical seal observe the sense of winding of the spring and the installation dimensions! If the old shaft is used, the seat must be free of residues. If necessary it must be re- lapped, too. O-Ring Old O-rings should be changed after disassembling. O-rings in full PTFE, also for new O-rings, has to be check whether a deformation after disassembling can destroy the sealing properties. Not welded coated PTFE rings need to be assembled in direction where the joint it not in mounting direction. This avoids unwrapping of the PTFE coat.

254 AKH-X Operating principle The AKH-X pump is a Side Channel system, self priming, segmental type. 1 A Side Channel stage consists of: A suction intermediate part (1), A discharge intermediate part including the Side Channel (2), A vane wheel impeller located between the 2 intermediate parts (3) The fluid entrance goes through the suction hole (4). The turning of the vane wheel impeller creates an under pressure at the beginning of the side channel and the liquid (with or without gas) is drawn in. The pressure generating is obtained by the repetitive re-entering of the liquid in the side channel (5). The liquid goes then to the next stage through the discharge hole (6). The air displacement channel (7) provokes a positive displacement effect so the gas remaining at the root of the vane wheel impeller is forced out through the gas slot (8) A side channel pump can de-aerate and degas the suction line by itself and is thus very suitable for suction lift operation. A side channel pump can handle large quantities of (entrained) gas. Mixtures up to a gas share of 50% are possible. The ability for self-priming and the handling of large amounts of (entrained) gas will guarantee continuous operation even in case of evaporation and therefore contribute to a higher level of safety in industrial processes. To avoid cavitation the distance between the liquid level and the entrance at the suction side of the pump is restricted. This distance is related to the NPSH or Net Positive Suction Head. This makes the AKH-X very suitable for pumping liquids near their boiling point at reasonable economic expenses. 4

279 Sterling SIHI GmbH 13th Repair hints The following repair hints are to be observed: Intermediate piece, item 10,11,12 The sliding surfaces can be re- turned up to 0,5 mm. Doing so the plan parallelism must be kept. Max. admissible peak- to- valley height is R t = 6 µ, deviation of the plan parallelism 10 µm. The sealing surface of the intermediate piece is to be re- turned, in order not to change the clearance of the vane wheel impellers. Up to construction size 3600 the depth +0,160 +0,130 and from size ,210 +0,180 has to be larger than the width of the vane wheel impeller. Is this recommended to re- turn not more than indispensably necessary. In case of an increased number of stages and utilization of the total turn- out dimension it might be better to install a combination of new and old stages, in order to avoid difficulties in assembling and performance (shaft length). Vane wheel impeller, item 30 From a reworking on the vane-wheel impeller should be refrained, as a reduced output might arise which cannot be calculated and thus the interchangeability is not more ensured. Bearing bushes, item 0241, 0242, and following The bearing bushes are glued in with a special glue. Before glueing in them, the corresponding places are to be cleaned carefully from probable residues and oils. Radial seal ring, item 426 When fitting the radial seal ring, the sealing lip must be in correct position; it has to point outwards in order to avoid excessive grease and to avoid the penetration of dirt. Gland packing rings, item 400 When fitting them, their correct number and the position of the lantern ring must be observed, in order not to cover a drain or hydraulic bore which may exist. Mechanical seal, item 500, 600 Check the O- rings for usability, replace worn out rings. Re- lap sliding surfaces, if necessary and check carefully for hairline cracks. When mounting the mechanical seal observe the sense of winding of the spring and the installation dimensions! If the old shaft is used, the seat must be free of residues. If necessary it must be re- lapped, too. O-Ring Old O-rings should be changed after disassembling. O-rings in full PTFE, also for new O- rings, has to be check whether a deformation after disassembling can destroy the sealing properties. Not welded coated PTFE rings need to be assembled in direction where the joint it not in mounting direction. This avoids unwrapping of the PTFE coat.

282 Side Channel Pumps CEH CEH 1201/ /6 with magnetic coupling TECHNICAL DATA Output: Delivery head: Speed: max. 35 m³/h max. 354 m (at 1450 rpm) max rpm Temperature: max. 180 C Casing pressure: PN 40 Shaft sealing: without shaft seal because of magnetic coupling Flange connections: DIN 2501 PN 40 Direction of rotation: anti-clockwise, seen from the drive on the pump CEH pump with shell APPLICATION CEH pumps are side channel pumps with NPSH inducer stage suitable to handle liquids which do not contain solid matters or abrasive admixtures. The NPSH inducer stage allows the operation under unfavourable pumping conditions at suction side, also at positive suction heads lower than 0,5 m. The special ability of these pumps to handle liquids at the boiling point has led to a wide field of application when condensate, distillate, coolant and liquefied gas shall be pumped. CEH pumps are applied in the chemical and petrochemical industry, in the pharmaceutical industry, in the plastic and rubber industry, in the surface finishing and hardening, in the foot, beverage and tobacco industry and in the air conditioning and refrigeration engineering. Pumps of the series CEH /6 with retaining sage to guarantee the min. filling level in the pump are especially applied to handle liquids under vapour pressure, also from underground tanks. DESIGN Pumps of the series CEH are horizontal, selfpriming side channel pumps, capable of handling gas along with the medium, in segmental-type construction, with open vane wheel impeller as well as pre-arranged centrifugal stage for attaining favourable NPSH values. The sealing to atmosphere is effected glandless by an isolation shroud; the driver power is transmitted contactless by a magnetic coupling. The use of stable permanent magnetic material ensures the transmission of the nominal torque and given protection against overload. On the basis of the compact close coupled design has been created a pumping unit that is easily to be installed. All IEC standard motors of the construction type IM B 35 are applicable. This design permits the operation of the pump without any additional coupling. Thus the alignment, a source of trouble, can be omitted. The pumps of the series CEH /6 are equipped with an additional retaining stage, behind the centrifugal stage, to prevent the emptying of the pump during standstill and thus keeping the selfpriming ability of the pump. The simple construction of the pump allows the assembly or disassembly without special tools. CONSTRUCTION Casing pressure: Construction size 1200 to 6100: PN 40 Please note: Casing pressure = zero head + inlet pressure Test pressure 52 bar resp. 33 bar Branch positions: Suction branch arranged axially, discharge branch radially upwards. Flanges: The flanges comply with DIN 2535/PN 40 Flanges according to DIN 2512 with groove and bored to ANSI 150 or 300 as well as to BS table F is possible. Hydraulics: First hydraulics, designation of this construction type: A. Bearings: The pump shaft runs in two sleeve bearings of pure silicon carbide (SiC), lubricated by the pumping medium The remaining axial forces are absorbed by axial sleeve bearings. Optionally available a friction reducing coating of the bushings to avoid critical operation. The outer magnet is directly fixed on the motor shaft consequently the external bearing becomes unnecessary. Designation of this construction type:. F Sense of rotation: Anti-clockwise when seen from the drive on the pump. Shaft sealing: Without shaft seals by an isolation shroud Transmission of the driving moment by a magnetic coupling.

Designation of this construction type: 4 Drive: By commercial three-phase A.C. motors, construction type IM B35. The selection is depending on the power consumption of the hydraulics, taking into consideration the density and viscosity of the pumping medium. For the motor rating the eddy current losses are to be added to the pump performance. Motors controlled by frequency converters are admissible. The motors and magnetic couplings indicated in the delivery programme are selected for a mains frequency of max. 50 Hz and are applicable for watery liquids. In case of differing speeds other magnetic dipole moments are necessary for the couplings. It is recommendable to check the selection with Sterling SIHI. Position: Usually the pump units are installed horizontally. The operation with vertically installed pump units is possible, but should be made only in consultation with Sterling SIHI because of the special instructions for starting-up, the support and thermal load of the drive motor. General remarks: The following pump series with magnetic couplings are available: Side channel pump without NPSH inducer stage: Series AEHB with vertical connection flanges Volute casing pumps acc. to: Series CBMD volute casing pump as per DIN EN bearing bracket design Series CBED volute casing pump as per DIN EN close coupled construction Series ZLKD volute casing pump close coupled construction - branches as per DIN / EN 733 Series ZLID inline pump For lower delivery heads: Series AKLA /AKVA single-stage inline side channel pump Technical documentation on these programmes is available on request. 2

284 FUNCTION Partial flow: For the cooling of the isolation shroud, heated up by eddy currents, a partial flow is derived which at the same time serves as lubricant for the ceramic sleeve bearings. The partial flow flows through two longitudinal bores in the discharge casing into the isolation shroud and is led back through the hollow bored shaft and the balance bores of the rear vane wheel impeller to its suction side. By the pumping capability of the inner magnet, inside the isolation shroud a circulation flow is created which flows through the longitudinal bores of the inner magnet towards the bottom of the isolation shroud and in the gap between inner magnet and isolation shroud back to the front side of the inner magnet. This circulation flow is nearly independent of the operating point of the pump. Consequently the cooling of the isolation shroud is guaranteed over the entire characteristic. By the pumping capability of the lubricating grooves in the thrust bearing disk a further flow is created through the bearing gap of the radial bearing over the thrust bearing towards the longitudinal bores of the inner magnet. Thus, also independent of the operating point of the pump, the lubrication of the bearings is guaranteed. The front radial bearings are lubricated by a partial flow that flows from the first side channel stage through the bearing gap towards the rear side of the NPSH impeller. Bearings: The SiC bushings are clamped axially on the shaft. The material combination secures that the clamping power is maintained also in case of high temperatures. The stationary bearing inserts are screwed to the discharge casing or pressed into the intermediate piece.. Alternatively bearings coated with adamantine carbon are available. Hereby are considerably reduced the coefficients of friction during dry operation and danger to the pump can be prevented. This coating is applicable up to 250 C. Safety: The magnetic bell is directly fixed on the motor shaft. The load on the bearings resulting from this is relatively slight and therefore a damage to the bearings very improbable. In order to protect the isolation shroud against internal or external damages by rotating parts, a stationary seat is installed in the stool and at the bearing insert. The distance from the rotors is smaller than that of the rotors from the isolation shroud. In order to obtain double leakproofness the application of fanless motors which withstand flooding, is possible. Then the sealed stool chamber serves to control the function of the isolation shroud. The pump has to be run with a motor load detector. It protects the machine against dry operation and operation beyond the range of the characteristic curves. VARIANTS Pump with shell applicable at high operating temperature and/or high operating pressure. Independent of the number of stages only two sealing points are necessary. The pump shown down on the right is equipped with a heat barrier and thus applicable at medium temperatures up to 400 C without cooling. Pumps with heating or cooling chambers for the handling of smeltings or boiling media also are available. For such cases special heating stages, instead of normal stages, are installed in the pump and thus offering the heating or cooling by means of liquid or vapour. 3
