The pumps are supplied with an external cutting function with 69,000 cuts per minute which makes the pumps ideal for pumping sewage water. Besides a good cutting function, the external cutting knife has the advantage of causing a swirling motion at the bottom of the sump so the sump remains clean.

The seal consists of two mechanical seals with silicon carbide running surfaces in a controllable oil chamber. These mechanical seals are assembled in a back-to-back construction so that the rotating part of the lower seal is completely protected against dirt adhesion.

The GRF submersible pumps are all supplied with a temperature cut-off switch that can be conncted externally.

For applications with chemically corrosive liquids it is easy to protect the cable using the special cable grommet.
