JRZP JEC Circumferential Piston Pumps

Every feature on the JRZP range has been specifically designed to make dismantling (whether for inspection, cleaning, or maintenance) quicker, easier and cheaper. What’s more, the forward-seal position places the seals in direct contact with CIP fluids.

Advantages JRZP Rotary Pumps

✔ Superior seal cleanliness lengthens seal life and minimizes seal flaking (product contamination).
✔ The seals are located directly behind the rotors, areas of product entrapment are eliminated for superior hygienic performance.
✔ In fact, the JRZP has the 3-A, EHEDG (European Hygienic Engineering and Design Group) certificate.

ZP series have same hydraulic and dimensional characteristics with U2 series, so, ZP series are compatible with U2 series. Compact seal design is key feature to make smooth operation even at high discharge pressure. Bearing oil seal made of stainless steel has corrosion-resistance so, it ensures longer life time even under the harsh cleaning condition.


A variety of seal options such as:

  • Single mechanical seal 
  • Double mechincal seal
  • Double O-ring seal allows the pumps to easily adapt to the changing conditions of service.
  • 2 shaft keys on rotors provide smooth operation at high discharge pressure or external vibration.
  • Oil bath type lubrication provides is more efficient than grease type lubrication.
  • Lip Seal

A variety of connection options are available such as SMS, RJT, DIN, ISO, Tri-Clamp and Flanges. Heating jacket on front cover and case are available that require controlling temperature.

Wetted parts are made of SS 316L.
