A series of experimental studies was made on the suction characteristics of a water ring vacuum pump sucking air with 100% humidity at 20, 30, and 40°C, which were identical to the water ring temperature. It was found that the characteristic curves at different temperatures agreed quite well with each other regarding the partial pressure of air. However, the characteristics are considerably inferior to the characteristics observed in conventional tests, where air is dry in the suction pipe. It means that the partial pressure of air in the impeller at the suction port is not in equiliblium with the partial pressure of air in the suction pipe.
