NEW!

Auto-Prime Valve
Allows for the constant removal of vapors and gases in Sodium Hypochlorite and Hydrogen Peroxide applications. The new AutoPrime Valve offers many features unique in the marketplace. The pump primes automatically and functions as an air-gap anti-siphon valve. Pump output is regulated by venting the discharge to atmosphere during each stroke, eliminating the need for a back-pressure device. In addition, it provides a vertical discharge, traditional in pump applications.

The AutoPrime Valve offers a flow range of .08 to 5.0 milliliters per stroke with a maximum pump output of 8.0 gallons per hour. Stroke rates are 5 to 100 per minute with a stroke length of 30 to 100%. Maximum operating pressure is 250 psi.

The new valve consists of four functional elements: the vent check valve, discharge check valve, the anti-siphon check valve and the return line. The vent check valve constantly removes gases when they are drawn into the suction line of the pump. If the pump remains idle for a length of time, the valve allows the gases to escape into the return/vent line.

The discharge check valve allows the discharge of fluid from the AutoPrime Valve. The design regulates the output at lower pressures, preventing over pumping. The anti-siphon check valve opens to atmosphere should a vacuum be introduced, creating an air-gap condition.
