Ampco ZP3 Series Clean-In-Place Circumferential Piston Pump

Ampco's ZP3 clean-in-place (CIP) pumps are Ampco's newest. ZP3 CIPs replicate the Universal I & II CIP pumps by Waukesha Cherry Burrell and are completely interchangeable with Waukesha and Wright-Flow pumps, but also contain several upgraded features. ZP3 CIP pumps, like all Ampco pumps, are also designed for maximum service life and reconditionability, and are available with pressure ratings up to 500 psi.

ZP3 Improvements & Advantages:

  • Front-Loading Seals located closer to the product flow for ease of maintenance
  • In-Line Cleanability without further modifications
  • New Rotor Case Design for maximum efficiency
  • Tungsten Carbide Seal Faces for longer life
  • New pumps can be reconditioned 2 to 3 times
