Screw Pumps

Screw Pumps are positive displacement pumps designed for smooth, pulse-free transfer of high-viscosity and abrasive fluids in industrial applications.

Screw Pumps

Product Overview

Screw Pumps operate using one or more intermeshing screws that rotate within a close-fitting chamber to transfer fluid along the screw axis. Known for their high efficiency, low pulsation, and excellent suction capabilities, screw pumps are ideal for handling a wide range of viscous, lubricating, and shear-sensitive fluids.
These pumps offer a consistent flow rate regardless of pressure changes, making them suitable for continuous-duty industrial processes. Their compact design, low noise, and gentle pumping action make them particularly useful in applications where fluid integrity is essential.
Screw pumps are widely used in oil & gas, chemicals, marine, and power plants for transferring oils, sludges, fuels, polymers, and more.
