Pulsafeeder GreenLine Metering Pump, 52.3 GPH @ 102 PSI, VFD Package (1‑phase in / 3‑phase out), PVDF wet end with Leak Detection

Pulsafeeder GreenLine Metering Pump, 52.3 GPH @ 102 PSI, VFD Package (1‑phase in / 3‑phase out), PVDF wet end with Leak Detection

The GreenLine‑GLM DM3DVFG‑L 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 corrosion‑resistant PVDF liquid end with FKM seat O‑rings 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. With 1″ FNPT suction/discharge connections, it is ideal for installations requiring non‑metallic wetted materials, leak monitoring, and VFD‑based flow control.
