Progressing Cavity Pumps
Positive displacement pumps for viscous, shear-sensitive, solid-containing, or food applications.
What is a progressing cavity pump?
In practice, a progressing cavity pump is usually another name for an eccentric screw pump (also called a mono pump or eccentric screw pump).
How does it work?
-
Inside is a spiral rotor (the “worm”) that rotates eccentrically.
-
That rotor rotates within an elastic stator with a double spiral shape.
-
Closed chambers are formed between the rotor and the stator.
-
As the rotor rotates, these chambers move from the inlet to the outlet → in this way, fluid is pumped continuously.
Advantages
-
Highly suitable for viscous liquids (sludge, polymers, oil, glue)
-
Can pump liquids containing solid particles
-
Virtually pulsation-free flow
-
Good dosing accuracy
-
Self-priming
Typical applications
-
Wastewater/sludge
-
Polymer dosing
-
Food industry (sauces, dough, puree)
-
Chemicals
-
Oil & gas
-
Biogas plants
