Motor Driven Chemical Metering Pumps

Vendors: LMI
LMI "G" Series Pumps

The “G” series LMI motor driven metering pumps are available for applications up to 175 psi (12 Bar).  These pumps are outfitted with mechanically actuated diaphragms (MAD), variable eccentric design for smooth output, durable metallic housing, optional variable speed drives for external control (4-20mA) available, and flow rates up to 312 GPH (1180 L/hr) @ 50 psi.  A robust metallic, worm gear drive coupled with the industrial duty variable eccentric stroke adjustment mechanism yields a 10 to 1 turn down ratio.  A direct coupling between the motor and pump diaphragm defines a MAD pump like this series. Like gear and hydraulically backed pumps, DC motors are often employed to work with proportional 4-20 mA DC signals.  They work well in municipal-sized jobs.
