A screw pump moves liquid axially through the chambers formed between intermeshing screws, giving a smooth, low-pulsation flow over a wide range of viscosities. Power Energy supplies screw pumps and twin screw pumps in Saudi Arabia and the GCC, including hygienic twin screw pumps for food, beverage and pharmaceutical duties. Tell us the fluid, flow rate and pressure and we will recommend a suitable model.
How a Twin Screw Pump Works
Two parallel screws rotate in opposite directions inside a casing. As they turn, sealed pockets of liquid travel from the suction side to the discharge side without being churned, so flow is steady and gentle on the liquid. Twin screw pumps are self-priming and can handle liquids that carry some gas, depending on the design.
Where Screw Pumps Are Used
- Oils, fuels and lubricants
- Viscous chemicals and resins
- Sludge and process liquids
- Food, beverage and pharmaceutical products (hygienic designs)
Why Choose a Screw Pump
- Smooth, low-pulsation flow
- Wide viscosity range, from thin to very thick liquids
- Gentle handling of shear-sensitive products
- Self-priming operation

What We Need to Recommend a Pump
- The fluid, its viscosity and temperature
- Flow rate and discharge pressure
- Solids content and abrasiveness
- Suction conditions and installation (indoor, outdoor, hazardous area)
- Duty cycle and any project or client specification

Frequently Asked Questions
What is a screw pump?
A screw pump is a rotary positive displacement pump that moves liquid along intermeshing screws, giving a smooth, low-pulsation flow.
What is the difference between a screw pump and a progressive cavity pump?
A progressive cavity pump uses a single helical rotor turning inside an elastomer stator, while a twin screw pump uses two intermeshing screws in a casing. Both are positive displacement pumps with low pulsation. Progressive cavity pumps suit sludge and solids, and twin screw pumps suit a wide range of clean to viscous liquids.
What liquids can a screw pump handle?
Screw pumps handle thin to very viscous liquids such as oils, fuels, chemicals and food products. Hygienic versions are available for food, beverage and pharmaceutical use.
Are screw pumps self-priming?
Yes. Twin screw pumps are self-priming within the limits of the design and the liquid.
