In many industries, fluid transfer isn’t as simple as pumping clean water through a straight pipe. When the material is thick, contains solids, or is prone to shearing, you need a pump that’s up to the challenge. That’s where the mono screw pump steps in—a rugged, reliable, and efficient solution for handling difficult fluids in demanding environments.

What Is a Mono Screw Pump?

A mono screw pump is a type of progressive cavity pump that uses a helical rotor turning inside a double-helix stator to move fluid through a series of sealed cavities. As the rotor turns, these cavities progress along the stator, gently pushing fluid from the inlet to the outlet without pulsation or turbulence.

Unlike centrifugal pumps, which rely on high-speed rotation to create flow, the mono screw pump operates on positive displacement principles. This allows it to maintain a consistent flow rate regardless of pressure or viscosity changes.

Applications of Mono Screw Pumps

Mono screw pumps are used across various Australian industries due to their versatility and ability to handle thick, abrasive, or shear-sensitive fluids. Common applications include:

Mining & Mineral Processing: For tailings, slurry, and thick waste materials
Oil & Gas: Pumping drilling fluids, mud, and crude oil with solids
Wastewater Treatment: Handling sludge, biosolids, and chemical additives
Food & Beverage: Transferring thick pastes, pulps, or liquids with suspended solids
Agriculture: Fertiliser, manure, and irrigation applications
Industrial Manufacturing: Viscous adhesives, resins, and emulsions

Because of their low shear and pulsation-free flow, mono screw pumps are also used in systems that demand gentle handling of sensitive materials.

Key Benefits of Using a Mono Screw Pump

Choosing a mono screw pump offers several distinct advantages over traditional pump types:

Handles High Viscosity: Excellent for molasses, sludge, or thick oil
Non-Pulsating Flow: Consistent flow rate ideal for metering and dosing
Self-Priming: Capable of dry running for short periods
Low Maintenance: Fewer moving parts reduce service intervals
Solid Handling Capability: Can pass solids without clogging or damage
Reversible Flow: Easily changed rotation direction for bidirectional pumping

This makes them especially popular in remote or critical operations where reliability is non-negotiable.
