Mono Screw Pump: The Efficient Solution for Viscous and Abrasive Fluids 2025
If your operation requires a reliable way to move thick, abrasive, or solids-laden fluids, a mono screw pump is one of the most efficient tools available. Also known as a progressive cavity pump, this technology is trusted across Australia’s mining, wastewater, agriculture, and manufacturing sectors.
At MultiTorque, we supply and service mono screw pumps built for harsh Australian conditions. Whether you’re handling sewage sludge, slurry, oil, or molasses, our solutions deliver consistent performance, low maintenance, and long-term value.
What is a Mono Screw Pump?
A mono screw pump is a type of positive displacement pump that uses a single rotating helical rotor inside a double-helix stator. As the rotor turns, it creates sealed cavities that move fluid progressively from the suction end to the discharge side. This design allows the pump to handle fluids that are:
- Highly viscous
- Abrasive
- Contain solids or fibres
- Sensitive to shear or agitation
Unlike centrifugal pumps, mono screw pumps maintain consistent flow rates regardless of fluid thickness or system pressure. This makes them ideal for both delicate materials and heavy-duty industrial use.
How Mono Screw Pumps Work
The core mechanism of a mono screw pump relies on the interaction between the rotor and stator:
- The rotor, shaped like a single screw, rotates inside the stator, a molded elastomer with a double-helix internal shape.
- As the rotor turns, it forms tightly sealed cavities with the stator.
- These cavities move the fluid forward in a smooth, progressive motion.
- This low-pulsation flow is perfect for metering, transfer, and dosing applications.
The result is a consistent and low-shear flow that protects both the pump and the fluid.
Advantages of Using a Mono Screw Pump
At MultiTorque, we often recommend mono screw pumps for applications requiring durability, precision, and adaptability. Here’s why:
✅ 1. Handles Thick and Abrasive Fluids
Mono screw pumps are built for the toughest materials. They easily transfer:
- Sludge
- Slurry
- Oil
- Paint
- Food pastes
- Chemical mixtures
Even fluids with sand, fibres, or solids are no problem thanks to the pump’s gentle but forceful action.
✅ 2. Low Pulsation and Consistent Flow
The progressive cavity mechanism delivers smooth, pulse-free flow, making mono screw pumps perfect for dosing systems and precise delivery.
✅ 3. Shear-Sensitive Fluid Friendly
Because there’s minimal turbulence or chopping motion, mono screw pumps are great for sensitive products such as dairy, emulsions, and cosmetic pastes.
✅ 4. Self-Priming and High Suction Lift
Mono screw pumps can self-prime and operate in low-pressure environments, even with suction lifts of up to 9 metres. This makes them ideal for tank emptying, mobile pumping, or remote site dewatering.
✅ 5. Reversible Operation
Many mono screw pumps can reverse flow direction without mechanical modification, adding flexibility to system design and control.
Common Industries Using Mono Screw Pumps in Australia
MultiTorque supplies mono screw pumps for a wide range of industries:
🏗️ Mining and Resources
Perfect for moving slurry, thick tailings, or abrasive mixtures. Their low-speed operation reduces wear and extends equipment lifespan.
💧 Wastewater and Sewage
Ideal for sludge transfer, digester feed, polymer injection, and grit handling. Their consistent performance and high solids tolerance make them a top choice in treatment plants.
🛢️ Oil and Chemical Processing
Suitable for moving lubricants, additives, and corrosive or high-viscosity fluids without damaging the product or pump.
🍯 Food and Beverage
Used for syrup, sauces, yoghurt, and other viscous or shear-sensitive products. Built to meet hygiene requirements where needed.
🌾 Agriculture
Commonly used for molasses, manure, effluent water, and nutrient solutions in irrigation systems.
