Abstract:
Dry pumps are used to pump a variety of gas mixtures from the semiconductor industry. The present invention provides a liquid ring pump located between the dry pump and an abatement device to remove soluble corrosive materials prior to the exhaust gases entry to the abatement device, the work fluid exhausted from the liquid ring pump being separated from the gas prior to entry to the abatement device.

Claim (Index 21):
The apparatus as claimed in  claim 20 , wherein said at least one dry pumping stage comprises two co-operating rotors supported for rotation in a stator by respective drive shafts, the liquid ring pump comprising a first liquid ring pumping stage comprising a first rotor supported for rotation in a first stator by a first of said drive shafts and a second liquid ring pumping stage comprising a second rotor supported for rotation in a second stator by a second of said drive shafts, and wherein said at least one dry pumping stage comprises an outlet connected to an inlet of the liquid ring pump for pumping gas from said at least one dry pumping stage to the liquid ring pump.
