Simple and economical pump design requiring only one shaft seal, able to handle fluids contaminated with large percentages of abrasive solids.

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.
