Introduction
Eccentric screw pumps, also known as Moineau pumps, are very good at transferring a wide range of fluids, from thin liquids to highly viscous substances. They’re particularly adept at handling difficult fluids such as solids-laden slurries.
These pumps provide a predictable and linear flow rate that is directly proportional to their operating speed. This allows precise control and easy adjustment to changing process requirements.
The typical flow range of progressive cavity pumps is quite wide, from as little as 0.6 litres per hour for precision metering applications to as much as 600 m3 per hour for large industrial processes and from 6 up to 24 or even 48 bar of pressure.

Eccentric Screw Pumps
A Subtype of Progressive Cavity Pumps
While often referred to as Progressive Cavity Pumps (PCP), Eccentric Screw Pumps represent a specific type within this broader category. It’s important to note that other pump designs, such as Lobe, Diaphragm, and Gear pumps, also fall under the PCP umbrella.
To clarify, Eccentric Screw Pumps can be considered a subtype or member of the Progressive Cavity Pump family, sharing the fundamental characteristic of positive displacement operation, but with a unique screw-and-stator mechanism that sets them apart.
