K.M.E. offer a new solution for high quality Twin-Screw Pumps, centred around cost saving, effective pumping, ease-of-use and reduced wear on moving components.

Twin-Screw Pumps are self-priming, double ended positive displacement pumps with external timing gears and bearings. These Twin-Screw pumps are available in over 80 sizes, with a design that provides complete axial balancing of the rotating elements, eliminating all metal-to-metal contact within the pump.

These pumps handle virtually any non-homogeneous fluid, regardless of viscosity, lubricity or abrasiveness. eg. seawater, bitumen, molasses, lime, acid, caustic solution or hydrocarbon.

Using a principle of no metal-to-metal contact within the pump housing, improvement to pump performance is achieved, even with non-lubricating and corrosive or contaminated fluids.

Chambers are formed in the pump housing as the two screws intermesh, these chambers fill with the fluid being pumped, moving it from the suction side to the higher-pressure discharge side of the pump.

The pump has also been designed to allow for reverse flow by simply changing the shaft direction, a great advantage for ease of installation.

In a test conducted, the graph below details the volume of oil pumped by a Twin-Screw Pump at 50°C (Red) and 100°C (Black). The graph shows how product can be pumped at lower temperatures with the aid of a slightly larger motor and have better efficiency on volume, thus saving costs on heating, as the product being pumped only needs to be heated to 50°C. In fact, the pump becomes less efficient when pumping a “thinner” product at 100°C, all of which proves for a significant overall energy saving.
