Hygenic PD Series

Rotary lobe pump for food, dairy, beverage and pharmaceutical duties; economical alternative to rotary piston pumps.

Best-value rotary piston pump, 100% dimensionally and hydraulically interchangeable with the competition.

Enhanced ZP1 (models 30 and larger) with patented O-ring repositioning for maintenance without disconnecting from piping.

Larger shaft and cleaner rotor nuts than the ZP1, making the ZP2 CIP-able and rated to higher pressure.

Fully CIP-able rotary piston pump with patented front-loading seal; no efficiency loss, seal serviced without removing rotor body or piping.

Fully assembled, remanufactured Ampco pumps held in stock for quick shipment - no pump exchange required.

3P Prinz (PERA-PRINZ) twin-screw positive-displacement pump - two pairs of non-contact screws give constant pulsation-free flow with high suction and low NPSH.

The Ampco Hygienic PD Series comprises rotary lobe and piston pumps for food, dairy, cosmetic and pharmaceutical duties. It handles very high viscosities — up to 1,000,000 cP — at up to 310 gpm and 500 psi, with chocolate-clearance rotors available. 3A-certified, CIP-able options run across the range.
