A centrifugal pump having a rotatable impeller that operates to drain liquid into the intake of the pump. An air-introduction passage connects with a subatmospheric pressure region at the back of the impeller. Air introduced through this passage is mixed with a portion of the fluid pumped, and the air-fluid mixture is expelled as the discharge of the pump.
