SIHI SuperNova Pump ZLI

SIHI SuperNova Pump ZLI is a single-stage and two-stage pumping units in a compact design with nominal performances according to EN 733 / DIN 24255 as well as additional size DN 25, where suction and discharge branch are arranged opposite for direct installation into 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. These compact pumps save space and are easy to install without the need for alignment.The pumps are used when clear resp. turbid liquids without any solid particles have to be pumped without any problems. Volute pumps of the  ZLI series in inline design have been constructed as space saving and easy to install pumping units with a standard motor.

Thanks to the process design it is possible to withdraw the whole insert unit without removing the casing of the pump from pipework. The individual shafts of the unit connected by a plug-in coupling facilitate the dismantling or the replacement of the motor without affecting the pump. The programme comprises. 14 pump sizes at present.
