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.

GA/GX series

When applying hot-melt adhesives, it is above all the evenness of the applucation that is the primary focus. Precision  metering does not only presuppose the fast and reproducible operating point setting, it also requires a low-pulsation feed-in of the conveyer medium. Once again, Oerlikon Barmag gear metering pumps offer considerable advantages since the gears are correspondingly designed and precisely manufactured.  

The pumps are oprimarily deployed in silicone processing and in hot-melt adhesive applications, but also for processing resins and polyurethanes and other higher-viscous liquids.
