Progressing cavity pumps
General Description
Used to pump or meter thin to highly viscous liquids,
pasty, neutral or aggressive, pure or abrasive liquids,
gaseous liquids or liquids that tend to foam,
even liquids with fibrous and solid components.
Functionality
Self-priming progressing cavity pump, the pumping elements
of which are the rotating rotor and the stationary stator.
The special shape of these two parts creates sealed
chambers, the contents of which are continuously moved
in an axial direction from the suction side to the pressure
side. Despite rotation of the rotor, no turbulence results;
the consistent chamber volume eliminates crushing forces.
