Blockage-free submersible pump with cutting device

The DRS series of submersible pumps have proved their reliability and durability for many years in various applications in which a limited drain pipe diameter is available. The pumps with cutting device are an often-chosen solution for the economic transportation of domestic or industrial waste water with coarse and/or long fibrous particles at a relatively high pressure. The cutting device ensures the waste water is suitable for transportation in pipes with a limited diameter.

Abrasion resistant, self cleaning, no maintenance

Apart from regular checks to ensure the settings are correct, this pump is essentially maintenance free. The cutting device has a self-cleaning function, which ensures the pump does not get clogged. Thermal protection in the motor and sealed bearings guarantees lifetime lubrication of the pump, which results in optimal performance. When the pump is unmounted at the end of its life, the stainless steel fastenings ensure that, even after many years of operation, it can be replaced without problems.
