Screw Pump: Powerful & Low-Pulsation Flow Solutions for Industrial Applications 2025

In industries where consistent, low-pulsation flow is critical—such as oil & gas, mining, chemical processing, and wastewater treatment—the screw pump stands out as one of the most reliable and efficient positive displacement technologies available today.
At MultiTorque, we work with businesses across Australia to supply, service, and support high-performance screw pump systems, including Netzsch NOTOS® multi-screw pumps and other leading brands. Whether you’re moving abrasive slurries, viscous chemicals, or light hydrocarbons, screw pumps provide a smooth and dependable solution with minimal wear and energy loss.
What Is a Screw Pump?
A screw pump is a type of positive displacement pump that uses one or more helical screws rotating inside a sealed chamber to move fluid. As the screws turn, they form sealed cavities that transfer liquid along the pump’s body from the suction to the discharge side.
Depending on the configuration, screw pumps can be:
- Single screw (progressive cavity)
- Twin screw
- Triple or multi-screw (like the Netzsch NOTOS® 3NS or 4NS)
These pumps are particularly effective at handling fluids that are:
- High-viscosity (e.g., oils, molasses, sludge)
- Shear-sensitive (e.g., emulsions)
- Containing solids or abrasive particles
- Requiring consistent, pulsation-free delivery
Benefits of Screw Pumps
Screw pumps have unique design advantages that make them superior in many industrial applications:
✅ Smooth, Non-Pulsating Flow
Unlike reciprocating pumps or gear pumps, screw pumps provide continuous, steady flow, reducing vibration and improving system stability.
✅ High Suction Lift
They offer excellent suction capabilities, making them ideal for challenging suction conditions or low NPSH scenarios.
✅ Self-Priming & Bi-Directional
Screw pumps are self-priming and can often run dry for short periods. Some models are also reversible, allowing for fluid transfer in both directions.
✅ Low Shear Operation
They handle sensitive fluids like polymers, food products, and emulsions without breaking molecular bonds or altering consistency.
✅ Long Service Life
With fewer moving parts in contact and minimal pulsation, screw pumps are known for extended operational life and low maintenance costs.
Applications of Screw Pumps in Industry
Screw pumps are commonly used in:
- Oil & Gas – Transfer of crude oil, multiphase fluids, fuel, and lube oil
- Chemical Processing – Acidic and viscous media, solvents, emulsions
- Mining – Dewatering slurry, tailings, thickener underflow
- Marine – Fuel oil transfer, bilge pumping, ballast systems
- Food & Beverage – Chocolate, syrup, dairy, wine must, and mash
- Water Treatment – Sludge handling, thickened biosolids, and polymer feed
Screw Pumps vs Other Pump Types
So how do screw pumps stack up against alternatives?
Pump Type | Flow Type | Best For | Limitations |
---|---|---|---|
Centrifugal Pump | Dynamic | Water, low-viscosity, high flow | Poor for viscous/solid-laden fluids |
Gear Pump | PD | Oil, lube, clean fluids | Pulsation, not ideal for abrasives |
Diaphragm Pump | PD | Chemicals, acids, slurry | Pulsation, wear-prone, less efficient |
Screw Pump | PD (smooth) | Viscous, abrasive, shear-sensitive fluids | Generally higher upfront cost |
