Twin Screw Pumps

Food Grade Twin Screw Pumps – EHEDG, 3-A & CIP

Food Grade Twin Screw pumps are hygienic positive displacement pumps which operate on the same proven twin screw pumping principle that was pioneered in the oil and gas industry over a century ago.

Today, twin screw pumps have revolutionised the hygienic manufacturing industries for a number of reasons which are detailed below…

Benefits of Food Grade Twin Screw Pumps


Gentle, smooth pumping action, without pulsing, that protects fluids & solids


Extremely wear-resistant and the screws are never in contact with each other


Capable of handling a wide range of speeds, viscosities & pressures – infinite pump applications


Twin Screw pumps can perform BOTH your process duty AND your Clean-In-Place (CIP) duties

How do twin screw pumps work?

When the non-contacting twin screws rotate within the pump head, fluid is pumped in an axial or ‘straight-line’ movement, being carried along within the gaps or chambers within the screws. This axial movement results in a low-turbulence, low-shear pumping action and the fluid discharge is constant and pulsation-free (laminar flow). 

In other rotary pumps, the fluid is transported circumferentially around the pump body via rotating impellers, lobes or rotors but inside a twin screw pump, the fluid is pumped axially, straight along the length of the twin screws. 

This makes the twin screw pump ideal for transferring slurries, soft solids, shear-sensitive fluids and/or liquids that could be altered or damaged by vigorous handling.

Q Pumps



BestPump Ltd is proud to be the exclusive UK distributor of this world-leading range of hygienic pumps.
