Pulsafeeder GreenLine Metering Pump, 269.5 GPH @ 73 PSI, 316 SS wet end, Leak Detection, No Motor (NEMA 143/145 Frame), 1.5″ FNPT
The GreenLine‑GLM DM7AYAH‑L‑NM is a mechanically actuated diaphragm metering pump in the DM7A hydraulic group, delivering 269.5 gph (1020 lph) at 73 psi (5 bar) with a stroke rate of 116 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 143/145 frame motor adapter for user‑supplied motor integration.
