  • Oerlikon Barmag will exhibit its pump lineup at UTECH Europe from April 23-25.
  • This exhibition will offer a platform to show innovations and networking within the sector.
  • With PUR playing a vital role in sectors like automotive, medical technology, and insulation, Oerlikon Barmag's precision gear pumps offer tailored solutions for complex processing needs.

Oerlikon Barmag is all set to present its pump portfolio at UTECH Europe from April 23-25 in Maastricht. UTECH Europe is the leading event for the global polyurethanes industry. Oerlikon Barmag's participation underscores its commitment to engaging with industry leaders and highlighting its contributions to the polyurethane market.

Polyurethane (PUR) has become indispensable in many areas of modern life – automobiles, furniture, shoes, medical technology and insulation. However, its processing is extremely complex and requires customised solutions for the respective application. This is where precision gear pumps from Oerlikon Barmag come in to meet the highest demands in the chemical industry – from extremely precise metering to increased service life and efficiency.

The gear metering pumps of the GM and GA series are mainly used for high-precision metering of demanding fluids under difficult conditions. The high-speed metering pump of the GM series has been specially developed for metering poorly-lubricating and abrasive media. The main advantage of the pump is the sealed product chamber. The space touched by the media is limited to the area around the gears. The external, ball-bearing support points in the high-speed pump are externally lubricated and thus prevent the product to be metered from causing damage due to insufficient lubrication. This considerably extends the service life of the pump, the company said in a press release.

In addition, the increased speed range (30 – 500 rpm) allows an extended application range, for which several pumps of different sizes had to be used previously. This saves on production changeovers and significantly reduces the number of spare parts required. With its low weight of 1.4 kg, the compact pump (ø65 mm) promises significant space savings as well as less strain on the machine.

In addition to the proven GM pump in a square design for standard metering tasks, the GM pump in a multi-stage design conveys low-viscosity media (eg. 250 bar, 100 mPas) under high pressure and the most difficult operating conditions. The round 2-stage GM pump has been specially developed for use in high-pressure technology. It masters the special challenge of pumping small flow rates with low viscosities. The pump is perfect for 0.05 to 20 ccm/rev feed sizes and is ideally suited for the production of PUR molded parts, block foam, refrigeration unit insulation or sandwich panels.

Manufacturing companies are constantly faced with the challenge of making their products and processes more efficient. Oerlikon Barmag supplements the proven GM series with the GA series, which has been specially developed for the demanding conveying of higher viscosity media. The GA series is available for conveying volumes of 1.25 – 30 cm³/rev (0.6-144 l/h). It is designed for pressures up to 200 bar, for viscosities up to 1,500 Pas and for temperatures up to a maximum of 225°C. With this pump series, Oerlikon Barmag offers customised solutions for process engineering processes where highly accurate and uniform metering is required.

High wear resistance, increased durability and robust appearance – the pump with a viscosity range from 1mPas to 1,000 Pas is tailor-made for pumping highly filled, highly viscous or abrasive media, such as filled adhesives, filled silicones or filled potting compounds. Eccentric screw pumps are used in sectors as diverse as the plastics industry, the automotive industry, the paint and coatings industry, the pharmaceutical industry and food technology. Customers benefit from a significant increase in productivity, as the maintenance intervals of the pumps are shortened and machine downtimes are significantly reduced.

The highlight of the eccentric screw pump is the multi-stage sealing system, which significantly extends the service life of the pump. The upstream shaft seal ring protects the slide ring seal from rapid wear caused by difficult media. The optimised alignment of the ball-bearing drive shaft, which runs centrally through the shaft seal ring, prevents any metal abrasion and thus ensures a significantly longer service life.

With the drum pump, the pump experts at Oerlikon Barmag are presenting a pump that is specially designed for conveying and metering highly viscous materials such as adhesives, silicones and other highly viscous materials from drums and other large containers and for pressures of up to 250 bar. One of its special features is that it discharges highly viscous materials from the drum and metres them directly without an intermediate stop.

The gear pump and drum follower plate are coordinated in such a way that the plate effortlessly reaches the bottom of the container, leaving behind only a very small residual quantity of < 1 per cent. This in turn reduces material costs and has a positive impact on the production process. The dosing process, which was previously carried out in two steps and required scoop piston and metering pumps, can now be combined with the drum pump in a single unit.
