Pulsafeeder GreenLine Metering Pump, 4.8 GPH @ 174 PSI, 230/460 V with VFD, with PVDF wet end
The GreenLine-GLM DM1CVAC is a mechanically actuated diaphragm pump designed for automated chemical dosing in industrial environments. Powered by a 230/460 V TEFC motor with integrated variable-frequency drive (VFD), it features a PVDF wet end with 0.5″ FNPT connection and delivers up to 4.8 gph (18 lph) at 174 psi (12 bar). Its sealed gearbox, oil bath lubrication, and dynamic stroke control make it ideal for dosing aggressive chemicals in water treatment, chemical processing, and power generation applications.
