FTS Twin Screw Pumps

Applications:

Twin screw pumps are ideally suited for low shear and gentle handling of products due to their operating mode and construction. The axial flow movement without change of direction, along with the non-contacting screws, provides optimal results.
.

Operating Principle:

The pair of screws rotates inside the pump casing, creating multiple separate chambers and pushing the trapped fluid inside based on the screw progression. The flow is particularly smooth and pulsation-free, with the pumped fluid flowing in an axial direction (rather than circumferentially, as is the case with centrifugal pumps). The result of screw rotation is a gentle movement of the displaced volume under non-turbulent conditions, making it ideal for handling shear-sensitive fluids or liquids easily prone to emulsion.
