Circumferential Piston Pumps

Circumferential Piston Pumps

Highly precision rotary lobe type pumps


The Waukesha external circumferential piston pump (ECP) design, is superior to the typical lobe pump design as the long sealing path of the winged rotors reduce slippage and offers gentle handling of particulates. They also perform better with liquids which require gentle handling, low viscosity, and high viscosity or contain abrasives. 

Circumferential pistol pumps have several advantages including:

  • Increased priming capabilities.
  • Very Sensitive and smooth pumping action.
  • A large fluid cavity allows pumps to handle abrasive liquids and large solids.
