SPX Flow>Waukesha Cherry Burrell’s line of positive displacement pumps focuses heavily on the industrial sector by engineering solutions optimized to tackle the toughest applications in a wide range of flows, viscosities and pressures. The state of the art WCB line features robust, low maintenance designs that elevate operational efficiency and accelerate throughput rates without compromising quality.
Products
Universal Series ECP Rotary Pumps
Unlike Rotary Lobe style pumps, the (ECP) External Circumferential Piston pumps from WCB utilize arc shaped rotor wings or pistons with tight tolerances that ‘scoop’ the pumped medium rather than pushing it through the cavity. This results in a long sealing path, greater volumetric efficiency, wide inlet /outlet orifices and less slip. These pumps perform well with high viscosity fluids, large solids and abrasive liquids without galling or seizing for maximum service life.
