Screw pumps are primarily used in applications across many different industries where clean, oil free vacuum is needed. The dry and contact free operation requires no lubrication in the pumping chamber leading to no process contamination and no pollution caused by the pump operation.
Driven directly by an integrated frequency inverter, these pumps no longer require any drive transmission. The integrated speed governor optimises the use of energy by matching delivery to actual demand. This creates high efficiency levels and minimises energy consumption, with the suction air remaining pulsation-free all of the time.
