Waukesha 220-UI

Waukesha 220-UI is specified for process lines that require stable positive displacement transfer of viscous, shear-sensitive, abrasive or hygienic products. It is relevant in food, beverage, dairy, personal care and industrial duties where product integrity, cleaning routines and uptime must be controlled. The Waukesha external circumferential piston principle uses arc-shaped rotor wings and long sealing paths to reduce slip and support smooth flow without valves in the pump chamber. The design keeps bearings outside the product zone and gives maintenance teams practical access to seals, rotors and wear components. Key selection checks for this model include maximum differential pressure 13.8 bar. The actual duty point should always be checked against medium behaviour, viscosity, cleaning method, inlet conditions and installation layout before ordering. By combining gentle handling, cleanable construction and planned spare parts support, Waukesha 220-UI helps reduce unplanned downtime risk and gives engineers a stronger basis for lifecycle-cost control.
