Non self-priming vertical high-pressure multistage centrifugal pump of in-line design
The pump shaft and the motor shaft of the IEC standard motor is connected with a clamp coupling. A special lantern roller bearing ensures optimum admission of axial thrusts. Intermediate bearings in the hydraulics guarantee a long service life.
The pump is suitable for water distribution and pressure boosting, industrial circulation systems, process water and cooling water circulation systems, fire-extinguishing systems, washing systems and irrigation. Furthermore, it can be used in fire-extinguishing systems, washing systems as well as for irrigation.
