Pumps of this nature feature close tolerance working parts that trap fluids in the pump’s body, preventing them from returning from the discharge side of the pump to the suction side when the pump is not in operation. In these types of pumps, the constant presence of fluid in the pump’s body allows the pump to better handle what are called “air pockets”. Air pockets are an accumulation of air bubbles in the pump’s working mechanism, which can impair proper pump operation. Self-priming centrifugal pumps overcome air binding by initially mixing any residual air in the pump’s working mechanism with fluid during the priming process. The “self-priming” capability of this type of centrifugal pump comes from the ability of the reservoir to retain liquid after its very first prime. However, nearly all self-priming pumps require water to be added to the pump casing to start the priming process. As long as a check valve or foot valve is installed on the suction pipe, and you never lose suction, you should not need to re-prime the pump again.
