Pulsafeeder GreenLine Metering Pump, 3.2 GPH @ 174 PSI, 230/460 V with VFD, with 316 SS wet end, with leak detection
The GreenLine-GLM DM1AVAC-L is a rugged, mechanically actuated diaphragm pump delivering precise chemical dosing with low cost of ownership. Powered by a 230/460 V TEFC motor with integrated variable-frequency drive (VFD), it features a 316 SS wet end, 0.5″ FNPT connection, and is rated for 3.2 gph (12 lph) at 174 psi (12 bar). This model includes a double-diaphragm leak-detection system with gauge and switch for enhanced safety. Its compact industrial design, sealed gearbox, and dynamic flow control make it ideal for safety-critical automated dosing in water treatment, chemical processing, and power generation applications.
