Vacuum Priming Systems - Fluid Power Journal

The vacuum pump system removes the air from the water pump suction line, as well as from inside the water pump chamber. As the air molecules are removed, the water from the reservoir is pushed up through the piping and replaces the void (lower pressure area) that this air previously occupied....<<more>>
