Metering gear pumps by Mahr Metering Systems are worldwide known also under the product name Feinpruef Spinning Pumps. They convince by highest precision, high resistance to pressure and temperature, as well as by excellent wear and corrosion resistance. Gear pumps by Mahr excel with particular low-pulsation metering. Since the first pump development in 1948 continuous improvements of metering pumps take place, and today the application possibilities of former spinning pumps could not be limited to a few words. To put in briefly, metering gear pumps by Mahr are high-precision positive displacement pumps for the exact metering of liquid media.
