Protection and beauty – gear metering pumps in lacquering systems
Remscheid, March 12, 2014 – the newly-developed high-speed metering pump GP500 will be the focal point of the Oerlikon Barmag trade fair stand at this year’s PaintExpo, the leading international trade fair for industrial paint and lacquering technology being held between April 8 and 11 in Karlsruhe (Hall 1, Stand 1539). Furthermore, Oerlikon Barmag will be showcasing its proven gear metering pumps, which are deployed in application systems for surface technology as well as in solutions for the economical application of paints and lacquers, in the production of automobiles and wind turbines, for example.
The demands made on ever-larger rotors on wind turbines are huge. They must withstand weather influences, in part over periods of decades, while remaining low-maintenance at the same time. In addition to the state-of-the-art compound materials from which the rotor blades are manufactured, highly-specialized coatings are decisive for their durability. Multi-staged lacquering processes ensure that the rotor blades are protected during use to the best possible extent.
The Oerlikon Barmag high-precision gear metering pumps, which are perfect for a wide range of applications, are particularly suitable for deployment in complex systems. The new high-speed metering pumps have been developed especially for lightly-lubricating and abrasive media. With their enlarged speed range (30 - 500 rpm), they cover a large application area for which several pumps of varying sizes have had to be used to date. For the manufacturer, this means less work when switching production and smaller spare parts inventories. The compact construction of the pump (ø65 mm) reduces the space required in the machine and the low weight (1.4 kg) keeps the load as low as possible, which in turn has a positive impact on the construction of the machine. The external, ball-bearing support points ensure that the pump is not only very durable, they also do not need to be purged as they do not come into contact with the respective product. The pump itself is clearance volume-free in design, which considerably shortens the required purging times and hence also significantly speeds up switching products.
