Pulsafeeder DM4D1FG Mechanically Actuated Diaphragm Metering Pump – Green Line Series, 72.9 GPH – 145 PSI

Pulsafeeder DM4D1FG Metering Pump – 72.9 GPH, 145 PSI The Pulsafeeder DM4D1FG metering pump delivers accurate chemical dosing up to 72.9 GPH at 145 PSI. As a result, it supports industrial water treatment systems that require steady flow and higher-pressure performance. Designed for demanding environments, this Green Line mechanically actuated diaphragm pump ensures consistent and reliable operation. In addition, its durable PVDF construction resists aggressive chemicals used in cooling towers, boilers, and industrial process systems. Therefore, operators benefit from long-term chemical compatibility and dependable service life. Moreover, the rugged drive assembly and precision stroke adjustment provide stable dosing control. The 10:1 turndown ratio allows simple and accurate flow changes as system demands shift. Consequently, the pump maintains reliable dosing accuracy with minimal interruption. Additionally, the sealed gearbox protects internal components from contamination and reduces maintenance requirements. The 0.54 HP motor, operating on dual voltage (115/230V, 60Hz), offers installation flexibility across facilities. Finally, because of its strong construction and high-pressure capability, the Pulsafeeder DM4D1FG metering pump integrates easily into chemical injection skids and automated industrial feed systems for cooling towers, boiler treatment, wastewater processes, and manufacturing applications.
