Oerlikon Barmag offers a huge selection of gear metering pumps for the non-textiles segment. 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 sealing with silicones, the accuracy of the melt flow is the major requirement. 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. Adding to the requirement of highest accuracy, metering pumps in silicone applications have to deal with high-viscosity media and high temperatures. Oerlikon Barmag pumps are designed for viscosities up to 1,500 Pas, back pressures up to 200/250 bar and operating temperatures up to 225 °C.
