OUR RANGE OF AVAILABLE AMPCO ZP SERIES
The Ampco ZP Range offers unmatched engineering advantages to the sanitary industry. The ZP circumferential piston pumps boast innovative features including upgraded materials, enhanced CIP-ability, interchangeability with most brands, and maintenance-friendly design. The ZP pumps are durable workhorses, thanks to their stainless steel bearing retainers and splash guards, 304 stainless steel gearcase, and one-piece 17-4 PH stainless steel shafts. These attributes, along with their patented technologies, translate to efficiency and longevity. All models are EHEDG-certified and conform to 3A standards.
ZP3 does not only boast a start-of-the-art design: an industry leader, it also delivers maximum efficiency and easy maintainability due to its patented front-loading seal design and unrivaled delivery times. Additionally, the bestselling positive displacement pump is CIP-able. The patented ZP3 also sits atop the others when it comes to cleanability.

PRINCIPLE OF OPERATION
A pair of winged pistons rotate in the pump casing around the circumference of the channel. As the rotation continues and as the pistons unmesh, a partial vacuum is created at the suction port. This causes the fluid to enter the pump. The rotation of the rotors transports the fluid around the channel. As the pistons re-mesh, they generate pressure, thus displacing the liquid at the discharge port. The direction of flow in a circumferential piston pump is reversible.
