Waukesha External Circumferential Piston (ECP) Design
Waukesha ECP Rotor

Waukesha developed the ECP style pump. The Waukesha design has arc-shaped rotor wings traveling in annular-shaped cylinders machined into the pump body. This produces a smooth flow without pulses or pressure peaks. This design coupled with Waukesha’s “88” alloy allows the pump to run with very tight tolerances.

The result is that Waukesha pumps are the most efficient sanitary PD pumps on the market. The design allows Waukesha pumps to run with very little slip even on water like thin fluids. The large fluid cavities in the Waukesha positive displacement design allow efficient pumps of high viscosity fluids as well. This ECP design yields much higher efficiency than comparable lobe or bi-wing pumps.
