Specifications
Details

Horizontal, single-stage volute casing pumps with dimensions and nominal ratings to EN 22858 in back pull out design, with uncooled balanced mechanical seal. The series ZEN has especially been designed for the trouble-free handling of hot water up to 230 °C. The back pull out design 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.
 
Applications:
The volute pumps of the series ZEN 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 application are the energy production, the heat transport 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.
