The Evak Residox 400 residue pump is designed for water removal in applications such as site drainage, emptying sumps, removing surface water and for pumping away floodwater. It features a rubber suction base that allows fluid to be pumped down to a level of 1mm on flat surfaces.

The pump is built to handle liquids containing small particles like silt and sand, the abrasion resistant vortex impeller reduces internal wear during operation and the stainless steel outer casing and cast iron pump housing makes these pumps suitable for tough environments.
