A 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, single houses etc.
This pump type is not ideal for pumping media with a high content of sand.
