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-7: This popular LMI pump drive has knobs for stroke length and frequency. Features auto/manual stroke frequency control, external pulse input (for 4-20mA input, add external Micropace A-D Converter), power control, remote on/off, low-level float switch input, and more.
