Pulsafeeder GreenLine Metering Pump, 41.2 GPH @ 145 PSI, VFD Package (1‑phase in / 3‑phase out), 316 SS wet end with Leak Detection
The GreenLine‑GLM DM4BVAG‑L is a mechanically actuated diaphragm metering pump in the DM4B hydraulic group, delivering 41.2 gph (156 lph) at 145 psi (10 bar) with a stroke rate of 116 spm. This model features a 316 stainless steel liquid end and includes the full leak detection package—double diaphragm, pressure gauge, and 24 VDC leak switch. The integrated VFD accepts 115/230 V single‑phase input and outputs 230/460 V three‑phase power to the TEFC motor, enabling variable‑speed control and improved process tuning.
