Pulsafeeder PULSAtron Series E Chemical Metering Pump
The Pulsafeeder LE12SA-WTCJ-XXX PULSAtron Series E is a solenoid-driven diaphragm metering pump for controlled chemical dosing. This 115 VAC model delivers up to 5 gallons per day (0.21 GPH / 0.8 LPH) at a maximum pressure of 250 PSI (17 bar).
Dual manual controls let you adjust both stroke rate and stroke length to set the chemical feed output for your application. The PVC pump head and fittings, PTFE (Teflon) seats and O-rings, and ceramic valve balls define this model's liquid-end configuration.

Features and Operation
Separate stroke rate and stroke length adjustments provide control over dosing output. The Series E uses an electronic timing circuit and a thermally protected solenoid with automatic reset. Panel-mounted indicator lights and a fuse support operation and circuit protection. Its water-resistant housing supports indoor and outdoor applications, while guided ball check valves help limit backflow and support priming.
The bleed valve helps release air during priming. The Series E is rated for continuous-duty chemical feed service.
Applications and Selection
Use this model for chemical feed duties that fall within its capacity and pressure ratings and are compatible with its wetted materials. Confirm the chemical, concentration, operating conditions, and required dosing rate when selecting a pump. Contact Water Treatment Resource for 230-volt options or PVDF liquid ends for acid applications.
