Pulsafeeder GreenLine Duplex-Head Metering Pump, 634 GPH @ 73 PSI, TEFC 115/230 V 1‑phase, PVDF wet end with Leak Detection, 1.5″ FNPT / ANSI 150# Combo
The GreenLine‑GLM DM7H1FH‑L is a mechanically actuated duplex‑head diaphragm metering pump in the DM7H hydraulic group, delivering 634 gph (2400 lph) at 73 psi (5 bar) with a stroke rate of 140 spm. This model features corrosion‑resistant PVDF liquid ends on both heads with FKM valve O‑rings and includes the full leak detection package—double diaphragm, pressure gauge, and 24 VDC leak switch. Equipped with a TEFC 115/230 V single‑phase motor (NEMA 143/145 frame), it is suited for duplex applications requiring non‑metallic wetted materials and leak monitoring.
