Cortech Product Feature – LMI Series G Motor-Driven Metering Pumps

LMI is a leading manufacturer of metering pumps and controllers. They are part of the Accudyne Industries family of brands. As a specialist in metering pumps, LMI offers many innovative designs. One great example of their ingenuity is the Series G line of motor-driven metering pumps.

Heavy-Duty Design

These motor-driven metering pumps feature a durable design, engineered to handle some of the toughest water treatment applications. LMI Series G pumps are available in two motor-driven models. This includes the SD and SG designs. They are certified with NSF/ANSI 61 and 372 for municipal compliance and excellent safety standards.


LMI Series C motor-driven metering pumps offer a heavy-duty industrial drive and rugged aluminum construction that will handle higher pressure applications and higher output even in the harshest of water treatment environments. These pumps feature a mechanically actuated diaphragm for smoother output and a design that also minimizes the risks of hydraulic oil contamination and system shock.


Innovative Features

The metallic worm gear drive and variable eccentric stroke adjustment mechanism provide smoother velocity profiles and a 10:1 turndown ratio. G Series pumps are available in three different frame sizes and can be configured with manual controls to enable precise stroke length adjustment. The reliable flow performance comes from high-performance check valves with machined seats. The motors are also very efficient, which minimizes the potential for heat buildup.


Durable and Dependable

Most importantly, these motor-driven metering pumps from LMI are built to last. The diaphragm is a high-performance PTFE design to reduce the stresses found in most metering pumps. All gear components operate in an oil bath to extend the pump’s operating lifespan. LMI Series pumps can handle flow rates up to 312 GPH (1180 Liters/Hour) and liquid temperature ranges of 14° – 122° F (-14° – 50° C).
