SIHI SuperNova Pump ZDI

SIHI SuperNova Pump ZDI are single-stage pumping units are compact in design with nominal performances according to DIN 24255 / EN 733 , where the suction and discharge branches are arranged opposite each other for direct installation into the pipe work. There is no common shaft for motor and pump. The motors used are standard motors. Due to the process design, it is possible to withdraw the whole insert unit without detaching the pump casing from the pipe work. There is no common shaft for pump and motor, standard motors can be used as the pump has its own built in bearing. At present, the programme comprises 8 construction sizes.

SIHI SuperNova Pump ZDI pumps belong to the family of heat carrier circulation pumps. These pumps in inline design have been constructed as space saving and easy to install pumping units with a standard motor. They will be mainly used for circulating hot water in closed pipe systems and vessel systems. The field of applications

Design:

The SIHI SuperNova Pump ZDI is a single-stage pump built in a compact design with nominal performances according to DIN 24255 / EN 733, where the suction and discharge branch are arranged opposite to each other for direct installation into the pipe work. There is no common shaft for motor and pump. The motors used are standard motors. Due to the process design, it is possible to withdraw the whole insert unit without detaching the pump casing from the pipe work. The individual shafts of the unit are connected by a plug-in coupling that will facilitate the dismantling or the replacement of the motor without affecting the pump. At present, the family of SIHI SuperNova Pump ZDI pumps comes in 8 different sizes.
