ZP2 Positive Displacement Pumps Withstand Higher Pressures

The ZP2 Series with its stainless steel gearcase, like all Ampco positive displacement pumps, is built for CIP-ability with enclosed rotor nuts.

It is designed to withstand higher pressures with its larger 17-4ph stainless steel shafts. In fact, the ZP2 is capable of withstanding pressures of up to 500 PSI and is 3A Certified.

Be sure to consider the ZP3 Series for true 100% CIP-ability and the most advanced CIP technology in sanitary positive displacement pumps.
