Pulsafeeder LMH6TA-KTC3-500 Metering Pump
The Pulsafeeder LMH6TA-KTC3-500 is a Pulsatron Series MP electronic solenoid diaphragm metering pump rated at 120 gallons per day (5.00 GPH) against up to 100 PSI, powered from 115 VAC, 50/60 Hz. The liquid end is PVDF with PTFE seats and O-rings and ceramic check valve balls, connected with 3/8 in ID x 1/2 in OD tubing. PVDF is the choice for aggressive and corrosive chemicals such as acids used for pH control, where polypropylene would soften or craze over time. It is fitted with the factory five function valve on the discharge, which adds pressure relief, back pressure, anti-siphon, air bleed and discharge drain functions in one assembly.
Control is fully automatic, with a scalable 4-20 mA input and pulse input, dual manual control, a stop function input and a signal level output relay, at up to 125 strokes per minute. The diaphragm pump design is sealless and leak free at the liquid end, guided ball check valves help it prime and hold prime, and the drive is fully enclosed with thermal overload protection on the solenoid. When the time comes to service it, the matching rebuild kit is KOPkit K6KTC3, which renews the head, diaphragm and both valve cartridges in one go.

Frequently Asked Questions
Q: Can it be mounted outdoors?
The enclosure is water resistant for indoor and outdoor installations, but keep it out of direct sun and use UV resistant black discharge tubing if the tubing is exposed.
Q: Why does the pump lose prime on sodium hypochlorite?
Hypochlorite releases gas that collects in the head. Mounting the pump with a flooded suction and bleeding the head regularly helps, and a degassing valve is the permanent fix.
Q: What is the most common wear item?
The check valve cartridges, followed by the diaphragm. A slow drop in output usually points to a valve that is not seating cleanly.
Q: Does the pump need a foot valve?
Yes. The foot valve and strainer keep the suction line full and stop debris from reaching the check valves, and the ceramic weight holds it at the bottom of the tank.
