Pulsafeeder GreenLine Metering Pump, 7.9 GPH @ 145 PSI, 230/460 V, with 316 SS wet end and Leak Detection
The GreenLine‑GLM DM2A3AC‑L is a mechanically actuated diaphragm metering pump engineered for accurate, reliable chemical dosing in demanding industrial and municipal applications. This model features a 316 SS liquid end for superior durability and chemical resistance, a TEFC 230/460 V 3‑phase motor, and the factory leak detection package. The leak detection system includes a double diaphragm, pressure gauge, and a 24 VDC leak detection switch for enhanced containment and early failure warning. Rated for 7.9 gph (30 lph) at 145 psi (10 bar), the DM2A3AC‑L is ideal for critical dosing applications requiring both performance and safety.
