Membrane deaerator apparatus

In a water ring type vacuum pump, an impeller (6) having a plurality of blades (6a) is rotatably provided in a pump chamber (3) communicating with an air inlet (1b) and an air outlet (1d), and a water inlet (1a) for feeding sealing water to a center portion of the pump chamber is further provided. Sealing water that has moved to a peripheral wall portion (3a) of the pump chamber (3) flows back to a center portion (3b) of the pump chamber (3). By this arrangement, the sealability of sealing water can be improved and the sealing water can be saved in amount.
