LMI Series G Motor-Driven Metering Pumps


LMI Series HH9 Metering PumpLMI Series G Motor-Driven Metering Pumps

The Series G Metering Pump is designed for high output applications. Water treatment chemicals, process additives, acids, out-gassing fluids, slurries, and many more applications are all handled with ease by this robust metering pump design. The drive incorporates a variable eccentric design which ensures smooth output and reduces system shock. The mechanically actuated diaphragm reduces the possibility of hydraulic oil contamination of process liquid which makes this an ideal pump for water treatment applications. DC variable speed drives are available for external control and automation.

    • NEMA 4X / IP65 Enclosure

    • High flow rates up to 300 GPH (1136 Liters/hr.)

    • Mechanically Actuated Diaphragm liquid end eliminates flow restrictions

    • Durable, metallic housing designed to withstand tough environments
