Priming Valves for Liquid Ring Vacuum Pumps

A Nash vacuum system is often used to prime one or more centrifugal pumps located above the free liquid levels of their suction sources. Vacuum draws liquid up until it fills each pump's suction line and floods its  volute. This condition can be established before the pump is started up, so that it is always primed and ready to begin pumping.
