GM Series Chemical Metering Pumps

High precision, pulsation-free chemical metering to 80 bar, at flows rates 0.5ml/min-30 l/min

The GM series for precision chemical metering and continuous dosing is available with capacities from 0.05 – 200 cm³/ rev. Wetted parts are made of stainless steel 1.4112 (440B), 1.4571 (316Ti) or 1.3343 (M2 high speed tool steel). 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 at high pressure is guaranteed even under the most difficult operating conditions involving thin and toxic media.
