MAHR Metering pumps

Gear pumps by MAHR excel in low-pulsation metering. They benefit from features like high precision, high resistance to pressure and temperature, as well as excellent wear and corrosion resistance. Suitable for a wide range of viscosities, these pumps can be used to meter low viscous media such as waxes and oils, as well as highly viscous media like pastes and polymer melts. Even products with fillers can be handled with these accurate metering pumps.

The use of metering pumps

Originally designed as spinning pumps, the MAHR metering pumps have evolved into metering pumps for various applications where highly precise dosing is essential. For instance, hotmelt and paint applications.

The metering pumps have a modular design to perfectly fit your process. Due to the standard connecting dimensions, the pumps can easily be modified for different flow ranges.

Paint pumps from MAHR are used for both conventional and water-based paints and assure excellent flushing results and shortest colour changing intervals.
The pumps can easily be integrated in robot operated systems for industrial and automotive paint applications.
