1 Side Channel Pumps CEH CEH 1202/ /7 TECHNICAL DATA Output: Delivery head: Speed: max. 35 m³/h max. 354 m max rpm Temperature: max. 180 C Casing pressure: PN 40 Shaft sealing: stuffing box or standard mechanical seal Flange connections: DIN 2501 PN 40 Sense of rotation: anti-clockwise, seen from the drive on the pump APPLICATION Sterling SIHI-side channel pumps in combination system: self-priming - handling gas along with the liquid - low noise pumps of the series CEH with NPSH inducer stage are used for problem-free pumping of liquids at unfavourable suction side pumping conditions. They are also applicable for positive suction heads below 0,5 m. The possibility to employ pumps of this series of different materials with uniform dimensions exchangeable SIHI standard components and of the same performance characteristics in particular for liquids at the boiling point has led to broad application in pumping of condensate distillate refrigerant LPG and boiler feed water. Especially in chemical plants, as well as distillation columns in the beverage industry the pumps of this series have been frequently used. Pumps of the CEH... / 7 series with retaining stage for level control of the liquid in the pump (protection against dry running) are specially applied for handling liquids under vapour pressure, also from underground tanks. CONSTRUCTION Casing pressure Max. 40 bar from - 40 C to C pressure rating for higher temperatures as per DIN 2401 Please observe: Technical rules and safety regulations. Casing pressure = inlet pressure + delivery head at minimum flow. Position of branches: Suction branch axial, discharge branch pointing radially upwards. Flanges: The flanges correspond to DIN 2535 PN 40. Flange design to DIN 2512 with groove and drilled to ANSI 150 as well as BS. Table F, is possible. Hydraulic: First hydraulic. Designation of this construction type: A. Bearing: DESIGN Pumps of the series CEH are horizontal, self-priming side channel pumps of handling gas along with the liquid, in segmental type construction with open vane wheel impellers. To obtain favourable NPSH values the CEH pump combines one or more side channel stages with a specially designed centrifugal suction stage impeller. The programme comprises 6 sizes each with 1-8 stages. The existing material designs allow 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 retaining stage. The programme comprises 6 sizes with 2-7 stages. The hydraulic components used in both series origin from our side channel pump assembly of prefabricated parts.. One grease-lubricated grooved ball bearing to DIN 625 and one liquid surrounded sleeve bearing. Designation of this construction type:. A Sense of rotation: Anti-clockwise, seen from the drive on the pump. Shaft sealing: The shaft can be sealed either by stuffing box standard mechanical seal. Dependent on the application conditions, the pump construction material and the number of stages, the shaft seals indicated on the back page can be used. PUMP TECHNOLOGY CEH P III / E 06/00

Technical documentation about these programmes will be readily supplied on request. main pumping line secondary line LPG filling station (diagrammatic representation) For placing LPG storage tanks aboveground, protection zones up to a length of 20 m a radius of 25 m are required. This space is available, only in very rare cases. When using a SIHI pump of the CEH.../7 series with special components for LPG suction lift operation it is possible to place the LPG storage tank underground and to install the pump unit aboveground as shown in the schematic graph. With this arrangement not only the technical safety expenditures (protection zone), but also the constructional expenditures of such a LPG filling station are reduced to a minimum. 2
