Pulsafeeder GreenLine Metering Pump, 52.3 GPH @ 102 PSI, 316 SS wet end, Leak Detection, No Motor (NEMA 56C)
The GreenLine‑GLM DM3DYAG‑L‑NM is a mechanically actuated diaphragm metering pump in the DM3D hydraulic group, delivering 52.3 gph (198 lph) at 102 psi (7 bar) with a stroke rate of 175 spm. This model features a 316 stainless steel liquid end for maximum durability and chemical resistance. 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.
