Pulsafeeder GreenLine Metering Pump, 57 GPH @ 145 PSI, PVDF wet end, Leak Detection, No Motor (NEMA 56C)

Pulsafeeder GreenLine Metering Pump, 57 GPH @ 145 PSI, PVDF wet end, Leak Detection, No Motor (NEMA 56C)

The GreenLine‑GLM DM4CYFG‑L‑NM is a mechanically actuated diaphragm metering pump in the DM4C hydraulic group, delivering 57 gph (216 lph) at 145 psi (10 bar) with a stroke rate of 140 spm. This model features a corrosion‑resistant PVDF liquid end with FKM seat O‑rings for excellent compatibility with acids, oxidizers, and aggressive chemical solutions. The “‑L” suffix adds the full leak detection package—double diaphragm, pressure gauge, and 24 VDC leak switch. The “‑NM” suffix indicates the pump is supplied without a motor and includes a NEMA 56C motor adapter for user‑supplied motor integration.
