Pulsafeeder LPE4SA-PTT1-XXX Metering Pump
The Pulsafeeder LPE4SA-PTT1-XXX is a Pulsatron Series E Plus electronic solenoid diaphragm metering pump rated at 44 gallons per day (1.85 GPH) against up to 100 PSI, powered from 115 VAC, 50/60 Hz. The liquid end is glass-filled polypropylene (GFPPL) with PTFE seats and O-rings and PTFE check valve balls, connected with 1/4 in ID x 3/8 in OD tubing. GFPPL is the general purpose head material and handles most water treatment chemicals, including cooling tower and boiler treatment programs.
Control is by manual on/off with on-line adjustable stroke rate and stroke length, each with a 10:1 turndown, 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 K4PTT1, which renews the head, diaphragm and both valve cartridges in one go.

Frequently Asked Questions
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.
Q: Can it pump directly into a pressurized line?
Yes, up to the rated 100 PSI at the injection point. The injection valve supplied with the pump keeps the line from backing into the discharge tubing.
Q: How do I set the output?
Start with the stroke length and stroke rate at a mid setting, measure what the pump actually delivers with a calibration column or by timing a draw down, then adjust. Output is proportional to both settings.
