Remscheid, March 01, 2016 – Oerlikon Barmag gear metering pumps are deployed in technical systems within chemicals, plastics, dyes and lacquers industries as well as in PUR applications around the globe. The Oerlikon Barmag pump experts will be presenting the division’s compre-hensive technology and efficient solutions for demanding applications to an international trade audience in Charlotte, USA, on April 6 and 7 (Hall C, Stand 824).

Metering under more difficult conditions

GM pumps – the experts for chemical applications
The GM range pumps are predominantly deployed in chemical applications. They are available for conveying volumes of between 0.05 and 200 cm³/rev. Among other things, they are characterized by short flow channels. Their specialty is the highly-accurate metering of chemical fluids under high pressures, even under the most challenging conditions, such as in the case of thin or toxic media, for example.

The square design from the GM series is the standard pump for many metering tasks. The expanded series, which now includes round designs, opens up a whole range of further application possibilities. The O ring seal in the plate package prevents leaks, for example. As an option, the round GM pump can be equipped with slide ring seal or magnetic coupling. Furthermore, it can be finished with various materials and coatings.

The development of the multi-stage pump expands the applications range for the GM series considerably. The round 2-stage GM pump has been developed especially for use in high-pressure technology. It masters the particular challenge of conveying small throughputs with low viscosities. The multi-stage GM pump conveys low-viscosity media (i.e. 250 bar, 100 mPas) even under high pressure and in the most challenging conditions.

Toughness is their specialty
Complementing the GM range, Oerlikon Barmag will also be exhibiting the GA range of pumps for conveying (filled and unfilled) media with higher viscosities at the UTECH. GA pumps are predominantly deployed in silicon processing and in hot-melt adhesive applications, but also in the processing of resins, polyurethanes and other liquids with higher viscosities. They are suitable for conveying volumes between 1.25 and 30 cm³/rev and are designed for pressures of up to 200 bar. With this, they offer tailor-made solutions for applications requiring accurately-defined, even metering.
