WebSummary. Self-priming pumps are necessary if a pump has to be located above the level of the liquid to be pumped. A self-priming pump must be capable of evacuating air from the suction line, thereby drawing liquid into the pump. When this has been achieved, the pump can revert to its normal pumping mode. Most types of positive displacement ... icaew climate change

WebThe pump can then be primed by merely opening the suction stop valve and allowing the force of gravity to fill the pump with liquid. The static pressure of the liquid above the pump also adds to the suction pressure developed by the pump while it is in operation. Another dis- advantage of centrifugal pumps is that they develop CAVITATION. Web9.27.3.1 Pump connections and facilities. At the suction side of the pumps common strainer facilities should be provided which should be easy to clean. The discharge line of each pump should be fitted with a check valve, a test valve, a pressure gage, and a block valve with locking device. Each pump should be connected separately to the ring ...
