Pulsafeeder GreenLine Metering Pump, 38 GPH @ 102 PSI, VFD Package (1‑phase in / 3‑phase out), 316 SS wet end
The GreenLine‑GLM DM3CVAG is a mechanically actuated diaphragm metering pump in the DM3C hydraulic group, delivering 38 gph (144 lph) at 102 psi (7 bar) with a stroke rate of 140 spm. This model features a 316 stainless steel liquid end for maximum durability and chemical resistance. The “V” motor designator identifies the integrated VFD package, which accepts 115/230 V single‑phase input and outputs 230/460 V three‑phase power to the TEFC motor. With 1″ FNPT suction/discharge connections, this configuration is ideal for installations requiring stainless steel wetted materials and variable‑speed control.
