Pumps / Positive Displacement Pumps
The durable Waukesha Clean-out-of-Place (COP) Positive Displacement "Can-Do Pump". Versatile in application, its reliability has made it the industry standard worldwide.
For more than half a century, Waukesha Cherry-Burrell® has been a leader in the design, manufacturing and application of external circumferential piston (ECP) style, rotary positive displacement pumps. Waukesha pumps are in service around the world and offer many key features, including:
• - Easy cleaning and disassembly
• - Flexible, three-way mounting
• - Field interchangeable single and double "O" ring and mechanical seals
• - Non-galling Waukesha "88" alloy rotors
• - 3-A approved, EHEDG certified
• - Maximum pressure: 200 psi (13.8 bar)
• - Temperature range: -40°F (-40°C) to 300°F (149°C)
In the Waukesha Cherry-Burrell design, arc-shaped “pistons” (rotor wings) travel in annular shaped 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.
FOR LOW VISCOSITY FLUIDS
Rotors, made of Waukesha “88” alloy, can be run with close clearance to the 316L stainless
steel fluid head, without galling or seizing should inadvertent pressure surges cause contact. The close clearances combined with the rotor geometry, which gives a long sealing path between the pump inlet and outlet, means low slip operation. As a result, you achieve: high volumetric efficiency, good priming ability, metering capability and good flow control.
