Pumps / Positive Displacement Pumps Universal 2 Bio-Pharmaceutical positive displacement pumps are designed for pharmaceutical and biotech processes. FEATURES 316L stainless steel rotors standard; non-galling Waukesha "88" alloy rotors optional 316L stainless steel product contact surfaces standard; 316L stainless steel or electropolish of all product contact surfaces optional Stainless steel bearing frame Additional option: seal flush Time-tested Waukesha Cherry-Burrell® rotary pump; circumferential-piston operating principle 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 efficiency, good priming ability, metering capability and good flow control. FOR HIGH VISCOSITY FLUIDS The large fluid cavities of the rotors ... plus the large, easy entry anti-cavitation ports, allow efficient pumping of high viscosity fluids, slurries or even liquids with large chunks or particles.
