Pulsafeeder GreenLine Metering Pump, 38 GPH @ 102 PSI, TEFC 115/230 V 1‑phase, 316 SS wet end with Leak Detection
The GreenLine‑GLM DM3C1AG‑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 316 stainless steel liquid end for maximum durability and chemical resistance. It includes the full leak detection package—double diaphragm, pressure gauge, and 24 VDC leak switch—for enhanced containment in critical chemical feed applications. Equipped with a TEFC 115/230 V single‑phase motor and 1″ FNPT suction/discharge connections, it is ideal for medium‑to‑high flow systems requiring stainless steel construction and leak monitoring.
