KPM is a series of bilge pumps intended for tougher pumping and can handle flows of coarser materials.
The pump is available in both 1x230V and 3x400V versions. The 1x230V pumps have a built-in heat shield that prevents the pump from being overloaded. The 3x400V pumps also have a built-in overload protection to prevent the pump from breaking during, for example, dry running.
