Pulsafeeder GreenLine Metering Pump, 38 GPH @ 102 PSI, VFD Package (1‑phase in / 3‑phase out), PVDF wet end with Leak Detection

Pulsafeeder GreenLine Metering Pump, 38 GPH @ 102 PSI, VFD Package (1‑phase in / 3‑phase out), PVDF wet end with Leak Detection

The GreenLine‑GLM DM3CVFG‑L 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 corrosion‑resistant PVDF liquid end with FKM seat O‑rings for superior compatibility with acids, oxidizers, and aggressive chemical solutions. The integrated VFD package 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. The “‑L” suffix adds the full leak detection package—double diaphragm, pressure gauge, and 24 VDC leak switch—providing enhanced containment and early warning for critical chemical feed applications. With 1″ FNPT suction/discharge connections, this configuration is ideal for installations requiring non‑metallic wetted materials, VFD control, and leak monitoring.
