摘要
In a two-stage liquid ring pump, gas leakage from the high pressure to the low pressure side of at least the first stage is substantially reduced and gas leakage from the second stage to the first stage is substantially reduced or eliminated by providing an annular seal member in the clearance between the first stage port plate adjacent the second stage and the adjacent end of the first stage rotor hub and supplying sealing liquid under pressure at least equal to the pump discharge pressure to substantially fill the portion of the clearance bounded by the annular seal member.
