A Twin Screw Pump is a Rotary Positive Displacement Pump that operates using 2 screws to move product through the pump casing. The Twin Screw Pump available from our range is a Sanitary Self-Priming Twin Screw Pump from Pomac Pumps.
Pomac are a family-owned company from The Netherlands who specialise in Hygienic Process Pumps, supplying the Pharmaceutical, Chemical and Food Industries.
The 2 large screws within the pump counter rotate, without touching. They create a vacuum as they pass the suction port, drawing liquid into the pump housing. As the screws rotate past the discharge port, the volume between them decreases which pushes the liquid to exit the pump through the discharge port.
The Twin Screw Pump is EHEDG certified, which is the highest hygiene rating available for a Sanitary Pump. The pump is manufactured from a high-grade Stainless Steel (316L) and is cast rather than welded, which ensures there are no crevices inside the pump that product can get stuck in. Similarly, the pump is finished with a surface roughness of 0.8 as standard, or 0.5 if requested. As well as the material and finish, the pump has been designed and manufactured with a minimal amount of dead space inside making cleaning of the pump more efficient.
The Sanitary Twin Screw Pump can self-prime up to 8m and can dry run for brief periods of time without causing damage to the pump.
As the screws inside the pump rotate but do not touch, they can handle solids up to 60mm without causing damage to the product or the pump itself.
The operating principle of the pump ensures that the pump provides a steady, pulsation free flow for those applications that cannot have pulsations in their fluid output.
Twin Screw Pumps can handle high temperatures up to a maximum of 140ºC.
Twin Screw Pumps can be used for a number of applications, including but not limited to:
