1 Type ZEND SIHI Model: ZEND / ZDND / ZHND Hot Water Transfer Pumps Product Reference Manual FPD-xxxx Experience In Motion
2 Volute pumps for hot water up to 230 C SIHI SuperNova ZEND TECHNICAL DATA Output: Delivery head: Speed: max. 600 m³/h max. 90 m max rpm Temperature: max. 230 C (1) Casing pressure: PN 40 Shaft sealing: balanced standard mechanical seal uncooled Flange connections: material design 1B DIN EN PN 40 2B DIN EN PN 40 Direction of rotation: clockwise, when looking at the pump from the drive end APPLICATION The volute pumps of the series ZEND are part of the overall programme heat transfer and circulation pumps. They are primarily used for circulation of hot water in closed pipe and vessel systems. Therefore their fields of applications are the energy production heat transport and the industry and here mainly in systems where hot water as heat carrier is given preference, despite its high systems pressure, over oil as heat carrier. DESIGN Horizontal, single-stage (2) volute pumps with dimensions and nominal ratings to DIN EN in back pull out design, with uncooled balanced mechanical seal. The series ZEND has especially been designed for the trouble free handling of hot water up to 230 C and is distinguished by: A double heat barrier that causes an optimal energy consumption by the pump and reduces the temperature level in the mechanical seal chamber to less than 100 C without external cooling circuit (see temperature curve on page 3). The service life of the mechanical seal increases considerably. A special design that automatically leads accumulation of gas to exhaust. Consequently the dry operation of the mechanical seal can be excluded. A programme that comprehends 29 construction sizes and thus guarantees an optimal solution for every operating point. The back pull out design, which permits the removal of the complete bearing unit towards the drive end without removing the pump casing from the pipe work. If a spacer coupling is installed it is also unnecessary to disconnect the motor. CONSTRUCTION Casing pressure max. 35 bar from 170 C to 200 C max. 32 bar from 200 C to 230 C Intermediate values can be obtained by interpolation. Please note: Technical rules and safety regulations. Max. casing pressure = inlet pressure + zero head Max. test pressure = 52 bar Flanges location: Axial suction flange, discharge flange radially upwards. Flanges: The flanges comply with DIN EN 1092 part 1 and part 2 resp. PN 40. Flange design to ANSI 300 is possible. Hydraulic: Designation of this construction type: A. Bearing: One grease-lubricated, reinforced antifriction bearing to DIN 625 and one internal liquid flushed sleeve bearing. Designation of this construction type: S Direction of rotation: Clockwise, when looking at the pump from the drive end. Shaft sealing: Code BG3: balanced standard mechanical seal seal face materials SIC/carbon elastomer EPDM (1) Temperature range 170 C to 200 C (2) Except for sizes to PUMPTECHNOLOGY ZEN P I / E 08/2015

ZEND AS BG volute casing 10.91, intermediate piece intermediate flange casing cover shaft impeller bearing bracket mechanical seal casing for mechanical seal shaft sleeve 52.90, sleeve bearing Heat barrier / shaft seal / bearing / feet arrangement Heat transfer installations have achieved a high level of technical development. Consequently the requirements on the pumps handling heat carriers have increased regarding operating safety, environmental protection, maintenance and operating costs. On the basis of many years experience and latest technical know-how the ZEND fully complies with these requirements. Special attention was paid to the above technical details. A favourable reduction in temperature is obtained towards the drive side by fitting a double acting heat barrier between the casing cover and the shaft seal housing. See illustration. Product-side heat losses are effectively prevented (energy saving). The temperature reduction makes it possible to use safely an uncooled mechanical seal up to a pumping medium temperature of 230 C. By special constructional shaping of the pump feed, displacements caused by thermal expansion are prevented to e great extent. For the vertical displacement only the measure h is decisive, since the rest of the foot remains cold. The horizontal expansion is taken up by the elastic foot bracings.

30 Volute pumps for hot water up to 180 C SIHI SuperNova ZHND TECHNICAL DATA Output: Delivery head: Speed: max. 600 m³/h max. 95 m max rpm Medium temperature: max. 180 C Casing pressure: PN 16 Shaft sealing: standard mechanical seal uncooled Flange connections: DIN EN PN 16 Sense of rotation: clockwise, when looking at the pump from the drive end APPLICATION The volute pumps of the series ZHND are part of the overall programme heat transfer and circutation pumps. They are primarily used for circulation of hot water in closed pipe and vessel systems. Therefore their fields of application are the energy production, the heat transport and the industry and here mainly in systems where hot water as heat carrier is given preference, despite its high system pressure, over oil as heat carrier. CONSTRUCTION Casing pressure Max 16 bar Please note: Technical rules and safty regulations. Max. casing pressure = inlet pressure + zero head Max test pressure = 21 bar Flange location: Axial suction flange, discharge flange radially upwards. Flanges: The flanges comply with DIN EN resp. PN 16. Flanges drilled according to ANSI (previous ASA) 150 can be supplied. DESIGN Horizontal, single-stage volute pumps with dimensions and nominal ratings to EN 733 in back pull out design. The series ZHND has especially designed for the trouble free handling of hot water up to 180 C and is distinguished by: A heat barrier that causes an optimal energy consumption by the pump and reduces the temperature level in the mechanical seal chamber to less than 80 C without external cooling circuit (see temperature curve on page 3). The service life of the mechanical seal increases considerably. A special design that automatically leads accumulation of gas to exhaust. Consequently the dry operation of the mechanical seal can be excluded. A programme that comprehends 22 construction sizes and thus guarantees an optimal solution for every operating point. The back pull out design, which permits the removal of the complete, bearing unit towards the drive end without removing the pump casing from the pipe work. If a spacer coupling is installed it is also unnecessary to disconnect the motor. Hydraulic: Designation of this construction type: A or B Bearing: One grease lubricated antifriction bearing to DIN 625 and one internal liquid flushed sleeve bearing. Designation of this construction type:. A Direction of rotation: Clockwise, when looking at the pumpfrom the drive end. Shaft sealing: Code BJ3: Unbalanced standard mechnical seal Seal face materials SIC/carbon Elastomer EPDM PUMPTECHNOLOGY ZHND E 08/2015
