Air is drawn into the pump by the vacuum produced as the impeller rotates and is emulsioned with the liquid contained in the pump casing. The air/liquid mixture is driven into the priming chamber where the air, which is less dense, separates out and vents through the delivery line while the liquid, due to the higher density, falls back and is recirculated. When all the air has been evacuated from the suction line, the pump primes and operated like a normal centrifugal pump. It can also handle a mixture of air and liquid. The check valve mouted in the pump suction port serves two purposes: it prevents the liquid from draining out of the suction line when the pump is not in operation, and if the line is drained by accident, enough liquid is retained in the pump casing for the pump to reprime. The delivery line must allow the air draw from the suction lime to vent to atmosphere.
