Warman (previously Wemco) is the market-leading US brand for vortex and screw impeller pumps in wastewater, solids and high grit applications, especially among municipal customers. A strong distribution network supports the brand's high recognition in this diverse market.
The Vortex pump technique developed by Warman is based on the principle of a whirlpool: a vortex is created by the rotating, recessed impeller, extended into the suction line, drawing the liquid / solids into the pump and then quickly through the discharge, whilst minimising the fluid / solids contact with the impeller and volute.
