Pulsafeeder GreenLine Metering Pump, 38 GPH @ 102 PSI, TEFC 230/460 V 3‑phase, PVDF wet end with Leak Detection
The GreenLine‑GLM DM3C3FG‑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. It includes the full leak detection package—double diaphragm, pressure gauge, and 24 VDC leak switch—providing enhanced containment and early warning in critical chemical feed applications. Equipped with a TEFC 230/460 V three‑phase motor and 1″ FNPT suction/discharge connections, it is ideal for industrial environments requiring non‑metallic wetted materials and leak monitoring.
