Small powerful waste water pump

The pump is designed for handling all types of waste water in municipal, industrial and commercial applications.

With this new pump, the Frankenthal-based manufacturer is launching a cost-efficient low-weight pump set which is compact enough to be installed in narrow sumps and tanks.

The pump generates a maximum flow rate of 16 cubic metres per hour and a discharge head of up to 29 metres. The new model will primarily be used in pumped drainage systems, for example where waste water needs to be drained from below the flood level, or in systems with long discharge pipes and insufficient natural slope for gravity drainage.

As the new pump is equipped with a cutter macerating any fibrous material in the fluid, reliable sewage disposal can be achieved by a pipe diameter of no more than 32 mm. This cuts investment costs for piping and valves.

The shaft is sealed off towards the motor by a shaft seal ring, and by a bi-rotational mechanical seal at the pump end, so the motor is protected against fluid ingress. A reservoir between the two seals, which is filled with environmentally compatible oil, ensures proper cooling and lubrication of the mechanical seal even if the fluid contains gas. Generously dimensioned ball bearings sealed for life support the stainless steel shaft.

All screwed connections are made of high-quality stainless steel and designed as M6 hex. socket head cap screws, so that the pumps can easily be dismantled even after years of hard pumping duty. A single tool will dismantle the entire pump, which makes servicing so much easier.
