Progressive Cavity Pump

A Progressive Cavity Pump is a type of a positive displacement pump which has a rotor rotating within a housing called a stator. The rotor is always metallic and the stator is made up of a rubber type of material. It looks somewhat like a screw thread – the fluid is between the cavities and the rotary motion of the rotor forces the fluid through from one end to the other.

Progressing Cavity pumps are used when a product needs to be handled gently and are used in all sectors of industries to convey almost all types of media continuously, smoothly, with low pulsation and dosing in proportion to speed. They are used for dosing applications where accuracy is required (multi stage pumps) their range covers from the smallest dosing pumps with flow rates of a few ml to high-performance pumps that pump up to 1000 m³/h.

One of the main advantages of a progressive cavity pump is that it is easy to regulate the flow of product simply by regulating the speed of the pump.

Flexachem are suppliers of the progressive cavity pump for the brand NETZSCH throughout Ireland.

To see for yourself how the  Netzsch NEMO® Progressive Cavity pump works – watch the video below.

The Netzsch NEMO® Progressing Cavity Pump is also available in Full Service In Place (FSIP®) design …. rotor and stator can be serviced in place without the need of removing the pump from the system.
