Progressing Cavity Pumps - Eccentric Screw Design, Positive Displacement Mechanism, Smooth Continuous Flow, Self-priming Functionality, Abrasion Resistant Elastomeric Lined Casing

We are making and supplying of Progressing Cavity Pumps in Hyderabad, Telangana, India. The ALLWEILER progressing cavity pump is a rotary self-priming positive displacement pump. The pumping elements are the rotating eccentric screw (rotor) and the fixed abrasion resistant elastomeric lined casing (stator). In the cross-sectional plane both are in contact with one another at two points forming two sealing lines along the length of the conveying elements. The fluid entering the suction area of the casing (typically located adjacent to the bearing frame) enters a cavity which is being formed as the rotor turns. As the pump shaft continues to rotate the cavity is sealed and the captured process fluid is displaced axially along the length of the casing to its ultimate exit point at the casing discharge (typically located at the extreme non-drive end of the pump). This smooth continuous pumping action ensures an even uninterrupted volumetric output from the pump and minimizes pressure pulsations at the pump discharge.
