Rotary Screw Pumps – Reliable Fluid Transfer for Industrial Applications 2025

In the demanding world of industrial fluid handling, equipment reliability isn’t optional—it’s essential. Whether you’re moving thick sludges, corrosive chemicals, or multiphase mixtures, the rotary screw pump stands out as a powerful and versatile solution.

At MultiTorque, we specialize in the supply, service, and repair of rotary screw pumps across Australia. With a proven track record of reliability in mining, chemical processing, water treatment, oil and gas, and food industries, these pumps have become an industry favorite for their durability, efficiency, and low-maintenance design.


What Is a Rotary Screw Pump?

A rotary screw pump is a type of positive displacement pump that uses two or more helical screws to move fluid through a sealed chamber. As the screws rotate, fluid is trapped between the screw threads and the pump casing and pushed toward the discharge side.

Unlike centrifugal pumps, which rely on high-speed impellers and kinetic energy, rotary screw pumps deliver constant flow regardless of system pressure, making them ideal for applications requiring consistency and accuracy.


Types of Rotary Screw Pumps

There are multiple configurations of screw pumps, including:

  • Single screw pumps (progressive cavity pumps)
  • Twin screw pumps (for multiphase or high-viscosity flow)
  • Triple and quadruple screw pumps (typically used in high-pressure hydraulic or lubrication applications)

Each configuration is tailored to specific flow rates, pressure conditions, and fluid types.


Benefits of Rotary Screw Pumps

Rotary screw pumps offer several significant advantages over other pump types, including:

✅ Smooth, Pulsation-Free Flow

The continuous motion of screw rotors delivers non-pulsating flow, ideal for sensitive applications like dosing, blending, or high-precision metering.

✅ High Viscosity Handling

Rotary screw pumps are built to move thick, viscous, and even abrasive fluids with ease—making them perfect for oils, sludge, molasses, and polymers.

✅ Low Noise & Vibration

Compared to reciprocating or gear pumps, screw pumps offer quieter operation with reduced mechanical stress on the system.

✅ Self-Priming and Dry-Running Capable

Most rotary screw pumps are self-priming, and some designs can tolerate short-term dry-running, increasing operational safety.

✅ Efficient Across Variable Pressures

Their constant volumetric displacement makes them suitable for systems where pressure fluctuations are common.


Applications Across Australian Industry

Rotary screw pumps are used in a wide range of sectors, including:

  • 🛢 Oil & Gas – Crude oil, fuel, multiphase liquids, and lubricants
  • 🛠 Mining – Slurry transfer, dewatering, thickener underflow
  • 🧪 Chemical Processing – Acids, resins, adhesives, polymers
  • 🧼 Food & Beverage – Chocolate, syrup, yogurt, and sauce transfer
  • 💧 Water & Wastewater – Sludge, biosolids, digester feed
  • 🚢 Marine & Transport – Ballast water, fuel transfer, cargo handling

Wherever reliability, flow stability, and material compatibility are essential, rotary screw pumps offer a serious performance edge.
