 | Self-Priming Principle | | |
| 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 operates like a normal centrifugal pump, it can also handle a mixture of air and liquid. The check valve mounted in the pump suction serves two purposes: it prevents the liquid from draining out of the suction line when the pump is not in operation, and if the suction 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 drawn from the suction line to vent to atmosphere.
UMD series pumps are self priming centrifugal pumps with open / semi open impeller handling polluted liquids with large diameter suspended solids. The solid rugged design with replaceable wear plate and back pull out design makes it most reliable option.
