When handling viscous, abrasive, or shear-sensitive fluids, standard centrifugal pumps often fall short. Thatโs where the progressive cavity screw pump comes inโa positive displacement pump designed to move challenging media with accuracy and control.
At MultiTorque, we supply, service, and repair progressive cavity screw pumps for clients across Australia. Whether you’re dealing with sludges, slurries, or sensitive chemical compounds, our team has the tools and experience to help.
What Is a Progressive Cavity Screw Pump?
A progressive cavity screw pump is a positive displacement pump that uses a helical rotor (the โscrewโ) rotating inside a stator to form moving cavities that carry fluid from the suction to the discharge end.
Also known simply as a PC pump, this design excels in low-flow, high-pressure scenarios. It handles a wide range of fluid typesโincluding thick, abrasive, and fragile fluidsโwhile offering non-pulsing, continuous flow.
Key Working Components:
-
Rotor: A precision-machined single helix metal screw
-
Stator: A double-helix elastomer sleeve that houses the rotor
-
Drive system: Typically electric motor-driven, with or without gear reduction
As the rotor turns inside the stator, a series of cavities open and close in a progressive motion, gently moving fluid forward without agitation.
Key Advantages of Screw-Type PC Pumps
-
โ Low shear โ Ideal for shear-sensitive materials
-
โ Steady, pulseless flow โ Even with high-viscosity fluids
-
โ Self-priming โ Handles suction lifts with ease
-
โ Excellent solids handling โ Capable of moving sludge, pulp, or slurry
-
โ Bidirectional operation โ Just reverse the motor for backflushing
The internal design of the screw pump also minimizes turbulence, which is essential when dealing with emulsions, sludges, or chemically sensitive substances.
Common Applications
Progressive cavity screw pumps are trusted in a wide range of industries. At MultiTorque, we support applications such as:
-
Wastewater & sewage treatment โ Dewatering sludge, digester feed, scum
-
Mining & minerals โ Tailings, slurries, and chemical additives
-
Oil & gas โ Crude oil, drilling mud, emulsions
-
Food & beverage โ Purees, fruit mash, dairy sludges
-
Agriculture โ Manure, feed slurries, thick fertilisers
-
Industrial chemicals โ Resins, adhesives, and polymer transfer
Their ability to maintain volumetric consistency even with highly viscous or abrasive media makes them a key asset in process-critical environments.
