Time-tested Waukesha Cherry-Burrell rotary pump; external circumferential piston (ECP) operating principle In the Waukesha design, arc-shaped “pistons” (rotor wings) travel in annularshaped cylinders machined in the pump body; the resulting long sealing path reduces slippage and produces a smooth flow of product without destructive pulses or pressure peaks and without valves or complex parts. Accurate and uniform displacement volume provides metering capabilities and good flow control. Exclusive Waukesha Design Features For Low Viscosity Fluids, Rotors, made of exclusive Waukesha “88”...
