Pulsafeeder GreenLine Metering Pump, 4.8 GPH @ 174 PSI, 230/460 V with VFD, with PVDF wet end, with leak detection
The GreenLine-GLM DM1CVFC-L is a mechanically actuated diaphragm pump designed for automated chemical dosing in safety-critical 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). This model includes a double-diaphragm leak-detection system with integrated pressure gauge and switch. Ideal for regulated dosing of aggressive chemicals in water treatment, chemical processing, and power generation.
