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.

Booster Pumps for Polymer Extrusion (GC, GE, and GE1M Series)

Ever smaller product tolerances characterize the development, i.e. for capacitor foils, packaging films, high-end monofilaments, drawn tapes, gas pipes, window profiles, etc. Our booster pumps optimize the polymer extrusion process allowing for precise pressure build-up and metering of polymer in extrusion lines. The use of booster pumps is particularly advantageous wherever recycled materials are processed.

Extruders are relieved and are therefore subject to less wear-and-tear. Booster pumps offset the impact of various material viscosities. Oerlikon Barmag booster pumps is a reliable and durable solution for many extrusion systems within the plastics-processing industry as well as in polymer plants for throughput increase, metering and compensation of pressure fluctuations. Oerlikon Barmag offers a comprehensive booster pumps portfolio from a single source with capacities ranging between 4,7 and 12.100 cc/rev.
