Our technologies enable our customers to achieve a closed-loop economy in the plastics industry, particularly in the packaging and chemical fiber industries. From melt preparation and cleaning to melt conveying, granulation, and spinning—we have all the technologies in-house, everything from a single source," says Barmag CEO Georg Stausberg, referring to innovative technologies for polycondensation and extrusion systems, new recycling solutions, sustainable manufacturing processes for filtration applications, and high-quality gear pumps.
Polycondensation and sustainability
High-quality melt has a direct impact on the end product. It forms the basis for high-quality bottle, film, and fiber polyester. OBHE's homogenization technology stands for the thermomechanical recycling of processed post-industrial polyester waste such as bottle flakes and film. The Oerlikon Barmag Homogenizer ensures a homogeneous melt, enabling a targeted increase in viscosity to produce defined rPET precursors for further processing, such as melt, granulate or fiber material for direct spinning.
Extrusion and recycling – extrusion pumps as a key factor
Ever more precise product tolerances are a key feature of the further development of modern products such as capacitor films, packaging films, monofilaments, stretched film strips, tubes, and window profiles. At this year's trade fair, Barmag will be presenting extruder pumps that significantly improve extrusion processes: The product flow is conveyed homogeneously thanks to constant pressure build-up and reduced pulsations. The result is extruded end products of consistently high quality. At the same time, the extruder is relieved, which leads to less wear. Another advantage is that fluctuations in material viscosity are compensated by the extruder pump. The wide product portfolio of the GE and GC series covers delivery volumes from 4.7 to 12,800 cm³/rev, offering tailor-made solutions for a wide range of extrusion requirements.
Pump solutions for polymer production and processing
Another focus is on the monomer, pre-polymer, and polymer discharge pumps of the GL and GD series. With delivery volumes from 4.7 to 21,100 cm³/rev, these pumps are suitable for different production capacities and a wide viscosity range—for maximum versatility in various processes. All pump models are also available as complete units, including the drive train and other components. This allows for individually tailored system solutions.
The ZP series continues to offer high-precision gear pumps that are ideal for demanding applications such as viscosity measurement thanks to their exceptional metering accuracy and wide viscosity range.
Precision that sets standards – metering technology for versatile industrial applications
The precise dosing of demanding media plays a central role in many industrial sectors. Whether in the chemical, plastics, paint, or coatings industry, Barmag pumps handle even the most complex PUR applications reliably and efficiently. The highly accurate and safe handling of toxic or low-viscosity media is particularly challenging. With the GM and GA series and the matching components, Barmag offers the ideal solution for these sensitive areas of application. Pumps in the GM series achieve precise dosing thanks to low-pulsation feed of the flow rate. The multi-stage GM pump conveys low-viscosity media even under high pressure. Ideal for precise dosing processes under the most demanding conditions.
