Twin screw pumps - get to know everything about this pump type
What are twin screw pumps?
Twin screw pumps are positive displacement pumps with rotating 'screws' which rotate in each other contactlessly so that the liquid is displaced in the axial direction.
A twin screw pump has two screws that interlock contactlessly, creating closed spaces between the screws. The contents of these spaces are constantly moving in axial direction from the suction side to the pressure side.
The fluid constantly moves through the twin screw pump without loss of lubrication or turbulence.
Constant, pulsation-free liquid flow
The rotating screws ensure a constant, pulsation-free liquid flow. Twin screw pumps are very suitable for pumping low and high viscous liquids without solid components.
Technical specifications of twin screw pumps
Maximum capacity 200 m3 / h
Maximum temperature 130 ° C
Viscosity from 0.5 to 1,000,000 mPas
Delivery pressure max. 30 bar
Twin screw pumps: for which applications?
A very high speed range makes it possible to pump a very wide range of different media or cleaning liquids.
In addition, it is possible to empty product-filled pipes with the relevant cleaning liquid due to the high pressure up to 30 bar.
High rotation speeds during cleaning work ensure a self-cleaning effect of the pump. The design of twin screw pumps makes it the ideal pump for hygienic applications.
Media in which twin screw pumps are used:
- Liquid sugar
