Zuwa’s submersible waste water pumps can transport solids up to a particle size of 55 mm, depending on the model. Pump body and rotor are made of grey cast and the shaft is made of stainless steel. Pumps are available with a flow rate from 225 up to 700 litres per minute with a pump head of 8 to 12 m.

The pumps are ATEX-approved for use in potentially explosive atmospheres such as bio gas plants, where the submersible waste water pumps can be used to remove condensed water from the dead well and return it to the fermenter.

Zuwa will exhibits the new ATEX pumps during the AGRITECHNICA trade show in Hanover, which takes place from November 15 - 19, 2011.
