Working principle of the progressive cavity pump:
A progressive cavity pump is a displacement pump that, with an interference fit of the rotor in an eccentric motion and a fixed stator, will form a seal cage within the pump, moving material from the inlet to the outlet, thus completing the conveyance of the medium within the seal cage.

The rotor
The rotor shape can be designed as per customer requirements. For a metal rotor, after surface hardening or a vacuum heat treatment, the hardness can reach up to HRC65-67.

The stator
Materials: NBR, NBRH, HNBR, EPDM and FKM- all of which meet various working conditions

Universal joint
Alternative universal joints include a pin type universal joint, pin and bush joint, sanitary universal joint, flexible universal joint, spherical teeth universal joint, cross universal joint and other joints.

Shaft seal
The packing seal and mechanical seal can be selected based on working conditions. The cooling system and flushing system can also be selected for the best possible way to prolong the shaft service life.

Driving system
The alternative driving system includes several high quality driving systems, such as SEW, NORD, ABB and others.
