Chemical Metering Pumps LMI Liquipro AutoPrime Valve Assemblies

LMI AutoPrime Valves allow for the constant removal of vapors and gasses inherent with pumping sodium hypochlorite and keep the pump primed automatically. This valve consists of four functional elements: vent check valve, discharge check valve, anti-siphon check valve and the return line.

AutoPrime valves fit LMI Series A, AA, B, C, J and P pumps that do not already have an autoprime liquid end. This valve is a great retrofit for standard LMI pumps that are used for pumping sodium hypochlorite (chlorine) and that experience problems with the pump periodically losing prime.

AutoPrime valves will automatically recirculate approximately 10 – 20% of the pump output back to the supply tank. Do not use this valve in flooded suction applications.
