JP Product Range

Centrifugal pumps of the JP-Series are especially suited for the hygienic and flawless movement of biologically challenging materials with a viscosity of 1,000 mPa s.

JPS Product Range

By combining the existing JP-Series with an upstream worm pre-stage a new generation of hygienic self-priming centrifugal pumps has been born.

The new Jabsco product range JPS makes available products with a high percentage of gas but a low sound level, the highest level of efficiency and excellent cleaning qualities. The JPS-Series also makes possible the evacuation of suction side pipeline plumbing systems. Thus only one pump is required for CIP-Return and product discharge. The new JPS-Series is utilized for all CIP-return-applications, for tank drainage, as well as for the discharge of products containing gas.

System Advantages JPS

The new JPS-series is utilized in the following instances: return applications, tank drainage, the discharge of gaseous products.


The self-priming Jabsco JPS-Series is based on the normal-priming centrifugal pumps in the JP-Series. A so-called screw-rotor is fitted upstream on the suction side of the JP-Series. The rotor is simply connected with screws on to the pump shaft at the place where the impeller nut is generally installed. The rotor housing is welded eccentrically on to the pump cover and ends at the pump’s suction connection.


When no gas cavities are present in the material being conveyed, the JPS-Series operates virtually like a conventional Centrifugal Pump. When the products being conveyed contain gas cavities the centrifugal force forms a liquid ring (2) in the screw-rotor and the gases are concentrated in the middle. The liquid ring seals the rotor blade (1) on the outside of the rotor housing (3) and also on the upper side of the rotor hub. This prevents trapped gases from flowing back. Thanks to the eccentric design of the rotor housing the gases collect underneath the rotor hub (4) and the rotor blades then convey them through the pump. A recirculation pipe (5) fitted on the outside of the pump ensures that liquid is constantly recirculated into the rotor housing, thus ensuring the pump’s suction capacity even when 100% gas is conveyed over longer periods of time. Self-priming (evacuation of the suction line) from a negative level is also possible with this pump.
