Twin Screw Pump
Twin Screw Pump: Advanced Fluid Transport Technology
Twin screw pump
Twin Screw pump represent a sophisticated positive displacement pumping solution designed for handling complex fluids across diverse industrial applications. These precision-engineered pumps operate on the principle of two intermeshing screws rotating within a pump housing to create a continuous series of sealed chambers that transport fluid from suction to discharge.
At the heart of a screw pump operation are two precisely machined screws with opposing helical profiles that rotate in synchronization. As these screws turn, fluid enters the suction side and becomes trapped in the cavities between the screw threads and the pump housing. The continuous rotation creates a smooth, pulsation-free axial flow that gently moves the fluid through the pump with minimal shear or agitation.
This design offers exceptional versatility for handling a wide range of challenging fluids, including high-viscosity products, multiphase mixtures (containing gas, solids, and liquids), and shear-sensitive materials. Industries including oil and gas, petrochemical, food processing, pharmaceutical, and maritime rely on twin screw pump for their reliable performance under demanding conditions

Screw pumps Key advantages
It has excellent suction capabilities with true self-priming functionality, bidirectional flow operation, and the ability to run dry for short periods without damage. The non-contacting screw design minimizes wear while providing consistent flow rates regardless of viscosity fluctuations. This makes twin screw pumps particularly valuable for applications requiring stable performance across varying process conditions.
Modern pumps incorporate advanced materials and seal technologies to ensure reliable operation with corrosive, abrasive, or hazardous fluids. Their space-efficient design delivers high capacity in a compact footprint, while the balanced hydraulic loads extend bearing life and reduce maintenance requirements.
With capabilities spanning from gentle product handling to high-pressure transfer operations, twin screw pumps deliver the efficiency, reliability, and process flexibility demanded by today’s most challenging industrial fluid handling applications.

Yes, twin screw pumps excel with viscous fluids (up to 1,000,000 cP) and can pass small solids (5–15mm), making them ideal for wastewater, sludges, and food pastes.
Twin screws maintain consistent flow up to 25+ bar with minimal pulsation, while gear pumps suffer from pressure spikes and accelerated wear at similar pressures.
Their low NPSHr (Net Positive Suction Head required) and gas-handling design ensures stable flow, even with vapor-prone liquids like LNG or gasoline.
With hardened steel screws and wear-resistant coatings, lifespan exceeds 20,000+ hours in abrasive duty—far longer than progressive cavity or centrifugal pumps.
Yes, but only for <5 minutes—dry running risks screw scoring. Models with PTFE-coated screws or water-flushed bearings tolerate it better.
