Grinder pump

A sewage grinder pump is a centrifugal pump equipped with a grinder system at the pump inlet, which cuts larger particles and fibres into a homogeneous wastewater mass. As a result, the risk of clogging of the pump and the pipe system is reduced to a minimum. 

More importantly, a grinder pump is ideal for pipe systems with smaller pipe diameters, where the flow is typically lower. This is relevant when pumping from remote areas, for example from single houses. This pump type is not ideal for pumping media with a high content of sand.  

The Grundfos SEG and SEG AUTOADAPT sewage grinder pumps are ideal for installation in pressurised networks using Grundfos prefabricated pumping stations (PPS).
