Robust pumps for sophisticated special fibers

At first glance, rowing boats, the Airbus 380, safety equipment and stadium roofing have very little on common. They receive their specific properties as a result of the use of special fibers, among other things: aramid fibers and carbon fibers are processed into special yarns that are frequently deployed as compound materials. These fibers are growing in demand as the world seeks to reduce its reliance on fossil fuels; new solutions are required to reduce weight and replace heavy metallic parts.

Aramid fibers are produced in a highly-chemical process that is extremely aggressive; the acrylic precursor used to manufacture carbon fibers is a different process, but again no less difficult. In these sophisticated processes, the gear metering pumps are not only responsible for the high-precision control of the melt transport; durability, resistance within aggressive environments and cost efficiency also play decisive roles.

Special materials for special tasks

The process, the expected pump lifespan and the maintenance frequency are the decisive factors for choosing the materials from which the pumps and their components are manufactured. For optimum results, Oerlikon Barmag offers solutions that intelligently combine the various materials and the latest technologies.

Whether in the case of surfaces with ceramic coatings, gears and shafts featur-ing DLC coatings, pumps made from cobalt alloys (StelliteTM) or robust and durable Oerlikon Barmag hybrid constructions comprising zirconium oxide ceramic and duplex stainless steel – the high-precision ZP- and GM-series pumps are design-optimized depending on the intended use. Various seal systems and customized drive concepts round off the pump program.

With this, Oerlikon Barmag customers have technologically-leading, reliable solutions for the high-precision metering of disparate media in complex processes for all applications at their disposal.

Oerlikon Manmade Fibers Solutions hosted successful Technology Day 2025 in India

Oerlikon Manmade Fibers Solutions recently hosted its highly anticipated Innovation and Technology Day at the Deltin Hotel in Daman by end of January 2025.

Oerlikon reports third quarter 2024 results, highlights strong execution in a challenging market landscape

In the third quarter of 2024, Oerlikon reported a stable operational Group EBITDA margin, despite challenging market conditions, thanks to a focus on pricing, cost management, and efficiency across both divisions. Group order intake saw a 4% year-over-year decline at constant FX, attributed to temporary market softness in Surface Solutions, while orders in Polymer Processing Solutions showed signs of stabilization.

Efficiency reimagined: economical, precise, compact

At this year's PaintExpo in Karlsruhe (April 14–17), Barmag will present an optimized design of its paint metering pump (Hall 3, Booth 3344). It impresses with its low weight, increased productivity, and extended service life. Specially developed for compact robot arms, the pump enables high-precision and economical paint application – ideal for industries such as automotive, aerospace, and renewable energies.
