SELF-PRIMING LIQUID RING PUMP METHODS AND APPARATUS Abstract of the Disclosure Stalling of liquid ring pumps during start- up is prevented, without the need for a separate liquid pump or other means for initiating or sustaining the flow of make-up pumping liquid into the pump, by providing a bypass conduit for initially conveying some pumping liquid from the relatively high liquid pressure side of the pump to the rela- tively low liquid pressure side of the pump. This helps the pump establish the internal liquid distribu- tion needed to form a viable liquid ring and create the gas pressure differential necessary to initiate and sustain the inflow of make-up pumping liquid.
