Metering Pumps for Industrial Applications

Oerlikon Barmag offers a large selection of gear metering pumps for varies industrial applications. We cover extremely diverse areas with our highly-efficient pumps – including silicone casting, dynamic mixing and oil spraying.

The perfect choice for all applications

The demands on the pumps are just as high as in the case of textiles – particularly considering that the demand is growing for tailored solutions for ever more complicated processes. And our expertise also allows us to provide even the most complex applications with the perfect solution.

GP/GM series

The GP series is designed for universal use with solvent paints and water-based paints. The paint metering pumps are perfect for the efficient administration of paints in various industrial applications, such as in automobile production, in the aerospace industry and in the manufacture of components for generating renewable energies.

GM-series gear metering pumps are designed as plate pumps. Here, the gears are fitted into the center plate of the pumps with a precisely-defined axial clearance.
