HV mechanical booster pumps |
The MB mechanical booster range operates on the Roots principle and need to be combined with a backing pump as they can not discharge to atmosphere. Impellers and rotors are constructed from cast iron, making them highly reliable even when pumping corrosive process media as it is not in the same concentration as it may be in backing pumps.
Product description The MB mechanical booster is a rotary displacement unit consisting of two profiled contra-rotating dynamically balanced impellers. These provide vibration free and quiet operation. This combined with advanced internal seal arrangement ensures no oil contamination of the process chamber. All models are capable of operating with up to a 500 mbar pressure differential across the pump, although thermal effects may have to be considered for extended periods of operation.
