Pulsafeeder GreenLine Metering Pump, 174 GPH @ 73 PSI, PVDF wet end, Leak Detection, No Motor (NEMA 56C), 1.5″ FNPT
The GreenLine‑GLM DM6DYFH‑L‑NM is a mechanically actuated diaphragm metering pump in the DM6D hydraulic group, delivering 174 gph (660 lph) at 73 psi (5 bar) with a stroke rate of 175 spm. This model features a corrosion‑resistant PVDF liquid end with FKM seat O‑rings for excellent compatibility with 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.
