Volute pumps SIHI ^uPerNova TECHNICAL DATA Delivery head: Casing pressure: Shaft sealing: Flange connections: balanced standard mechanical seal uncooled clockwise, when looking at the pump from the drive end 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 and here mainly in systems where hot water as heat carrier is given preference, despite its high systems pressure, over oil as heat carrier. Casing pressure Intermediate values con be obtained by interpolation. Please note: Technical rules and safety regulations. max. casing pressure = inlet pressure + zero head Flanges location: Axial suction flange, discharge flange radially upwards. The flanges comply with DIN EN 1092 part 1 and part 2 Flange design to ANSI 300 is possible. Horizontal, single-stage volute pumps with dimensions and nominal ratings to DIN EN 22858 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 • 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. Designation of this construction type: A. One grease-lubricated, reinforced antifriction bearing to DIN 625 and one internal liquid flushed sleeve bearing. Designation of this construction type: S Clockwise, when looking at the pump from the drive end. Shaft sealing: balanced standard mechanical seal seal face materials SIC/carbon elastomer EPDM

Material design: * for sizes 065315, 080315, 100315 material volute casing GP 240 GH. Casing gasket: The casing is sealed by a flat gasket of graphite. Designation of this construction type: 2 Motor power: Using commercial electric motors, type of construction IM B3. To determine the drive power we recommend the following safety margin: The following speeds are to be observed: The max. speeds result from the permissible peripheral speed of the jmpeller or from the shaft load admissible at higher temperatures, Bearing bracket / pump size: General remarks: For equipping hot media systems a...

Sectional drawing and nomenclature 44.10 casing for mechanical seal 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...
