Pulsafeeder GreenLine Metering Pump, 7.9 GPH @ 145 PSI, 115/230 V, with PVDF wet end
The GreenLine‑GLM DM2A1FC is a mechanically actuated diaphragm metering pump designed for accurate, reliable chemical dosing in demanding industrial and municipal applications. Powered by a 115/230 V, 60 Hz TEFC motor and equipped with a corrosion‑resistant PVDF liquid end, it delivers 7.9 gph (30 lph) at 145 psi (10 bar). The DM2A1FC features a sealed gearbox, auto‑locking stroke adjustment, ceramic check balls, and 0.5″ FNPT connections—making it ideal for aggressive chemicals, oxidizers, and off‑gassing fluids.
