Pulsafeeder GreenLine Metering Pump, 41.2 GPH @ 145 PSI, TEFC 230/460 V 3‑phase, PVDF wet end with Leak Detection
The GreenLine‑GLM DM4B3FG‑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 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. With a TEFC 230/460 V three‑phase motor and 1″ FNPT suction/discharge connections, it is ideal for applications requiring non‑metallic wetted materials, leak monitoring, and 3‑phase power.
