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.

GM series

Oerlikon Barmag metering pumps are used mainly for high-precision metering of chemical fluids. Accurate metering at high pressure is guaranteed even under the most difficult operating conditions involving thin and toxic media. The metering pump series for chemical applications is characterised by short flow channel paths, whereby all parts coming into contact with media are manufactured from the base material 1.4112 (martensitic chromium steel).
