Self Priming Pumps

In many applications, a pump has to be placed above the level of the liquid, for example, when emptying an underground storage tank.  At start-up, there will be air in the suction line and before the pump can discharge the liquid, this air must be evacuated or displaced.  Pumps are optimised to move a particular liquid; evacuating a gas is a very different challenge.

Ideally, for these applications, a pump is required that can evacuate air from the suction side at startup before commencing its normal pumping mode.  Such a pump is considered to be self-priming.
