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.



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.
