A Superior Self-Priming Positive Displacement Pump

We have partnered with global positive displacement pump leader Allweiler to help you get the quality you need.


This is a rotary self-priming positive displacement pump. The pumping elements are the rotating eccentric screw (rotor) and the fixed, abrasion resistant, elastomeric lined stator.

In any cross-sectional plane, the stator elements are in contact with one another at three points or two points. These points form three or two seal lines along the length of the stator elements. The material is contained in the sealed enclosed cavities, which are formed as the rotor rotates and is displaced axially and continuously from the suction to the discharge or the pump.

PC technology is ideal for pumping a wide range of liquids including highly viscous, neutral or aggressive fluids with entrained air, or with fiber and solids content.

ALLDUR® Stators Extend Pump Life and Lower Your Total Cost of Ownership

PC Pumps
A stator’s chemical formula determines how long the elastomer will last and, therefore, how much you will spend on maintenance and spare parts. This savings, or extra expense, will be a factor over the life of the pump and can significantly impact your operation and your total cost of ownership.

With this in mind, CIRCOR developed the new ALLDUR® formula specifically to maximize durability and efficiency for industrial wastewater applications.
