Setting a New Standard in Sanitary Pumps

Ampco engineers have enhanced pump longevity by adding features like the stainless splash plate to reduce potential damage to bearings from water intrusion during the wash-down process – eliminating a major cause of bearing failure.

Each model in the ZP Series lineup has specific features that are desirable for a wide variety of sanitary applications. For example, the ZP1+ features an enhanced O-ring seal that can be changed without disconnecting piping from the pump.

The Ampco Pumps team continues to redefine engineering excellence by offering customers the best sanitary positive displacement pump value and versatility in the marketplace.

Our goal at Ampco is to set the bar in sanitary pump technology to increase ease of maintenance, extend performance, and extend the life of Ampco’s PD circumferential piston pumps.
