Theory of Operation
The Waukesha Universal Series of pumps use the time-tested circumferential-piston operating principle. The 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.
Because the rotors are made of Waukesha non-galling Alloy 88, the rotors can be run with exceptionally close clearance with the 316L stainless steel fluid head, without having to fear 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 even with low viscosity fluids. This means you get high efficiency, good priming ability, metering capability, and flow control everytime you use a Waukesha Universal Pump.
Additionally, because of the large fluid cavities in the rotors, plus the large, easy entry anti-cavitation ports, the Universal Series of pumps allow efficient pumping of high viscosity fluids, slurries, or even liquids with large chunks or particles.
