The special AUTOPRIME head on this LMI pump is specifically designed for off-gassing liquids like bleach, sodium hypo and chlorine. AUTOPRIME heads use 3 checks: one suction check at the bottom, one discharge check out the front-center, and one AUTOPRIME de-gassing check on the top. By design, any gas in the head is automatically relieved thus stopping vapor-lock of the pump. This LMI pump discharge also includes LMI's 4FV four function valve.
LMI PUMP DRIVE CONTROL TYPE-1: This basic LMI pump drive has separate knobs for manual stroke frequency and stroke length adjustment providing a large turndown for chemical feed dosing. Features manual control only of this solenoid diaphragm metering pump for the basic chemical dosing system.
