Priming Valves

Priming Valves for Liquid Ring Vacuum Pumps

Our priming valves were designed specifically to be used in NASH vacuum pump priming systems. They are extremely simple but dependable and durable and have proven to be in successful service for nearly fifty years.

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.
