Progressive cavity pumps for viscous liquids
Progressive cavity pumps can act as motors by reversing the process and pumping fluid through the interior, as used in oil field drilling with mud injection. Other industrial applications includeÂ
Â
-
Food processing
-
Sewage treatment
-
Viscous chemicals handling
-
Mine tailings slurry disposal
-
Lubrication and fuel pumps.
What is a progressive cavity pump?
Attributed to the 1930s French aviation turbine pioneer, Rene Moineau, progressive cavity pumps are designed to move fluids. They do this by rotating a sequence of small, fixed shape cavities, enclosed within the pump casing, similar in principle to the Archimedean screw.
How does a progressive cavity pump work?
Progressive cavity pumps have a metal rotor which drives a stator through a chain. This fills cavities with equal amounts of fluid and pushes it through the pump outlet. The progressive aspect refers to the tapering and overlapping of the cavities toward their ends, which avoids any pulsations in the flow.Â
Some of the other main advantages of these pumps are that the volumetric flow rate is proportional to the rate of rotation, enabling them to be used in fluid metering. Meanwhile, the low levels of shearing make them suitable for pumping viscous materials.
Popular progressive cavity pump manufacturers
Our range of progressive cavity pumps includes various models by Mono for different applications. Renowned for their pioneering technology, Mono progressive pumps deliver unmatched reliability.
The M range are compact progressive cavity self-priming pumps that can handle viscous liquids and random solids. They have suction lifts up to 26ft (8m) so they can be installed away from the liquid level for easy maintenance.
Progressive cavity pumps from Anchor Pumps
Progressive cavity pumps from Anchor Pumps have relatively long service lives, provided they are not exposed to transporting abrasive materials.
