Description:
Vertical centrifugal pump in version with support bars for wet installation
The pump is driven via a flexible coupling by a three-phase motor. The pump shaft is
double supported by a bearing support. The shaft is no longer guided in the impeller
area; therefore, the maximum construction length is limited. The closed impeller conveys
the liquid in a separate support tube to the pump outlet.
Field of application:
Pump for continuous use, suitable for dry running, for transferring and circulating of neutral
or aggressive liquids in the chemical industry and chemical engineering, electroplating
industry, steel or stainless steel pickling plants, flue gas decontamination, exhaust air
purification, water and wastewater treatment.
Characteristics:
Safe to run dry, for continuous use; motor changeable
