GM Series Rectangular Industrial Metering Pumps

Precision gear metering pumps for accurate fluid metering and control

The GM rectangular series for precision fluid metering and continuous dosing is available with capacities from 0.05 – 20 cm³/ rev. Wetted parts are made of stainless steel 1.4112. These side-ported pumps are built to the same precision as the GM round series, but with fewer options for materials, seal types and sizes.

These hard-wearing pumps are used for precision metering and dosing of chemicals, additives, catalysts, resins, polyurethanes, silicones, adhesives, sealants, oils, dyes and paints. Accurate metering is guaranteed even under the most difficult operating conditions involving low to high viscosity media.
