Demanding material requires customized pumps

As soft foams, PUR in car seats, furniture upholstery and footwear and, as rigid foams, in insulation materials for buildings and cooling units. Vehicle manufacturers use it to produce composite components, while virtually every industry deploys cast PUR elastomers to create cushioning elements, rollers and many other items. This flexible material harbors huge potential and industrial competition is correspondingly dynamic: in demand are tailored PUR processing solutions for highly-efficient, rapid-response and, above all, environmentally-friendly mass production.

GM and GA pumps series for challenging applications

Oerlikon Barmag has been catering to the growing requirements with its gear metering pumps for many decades now. At the Moscow trade fair, the Remscheid-based company will be presenting its GM and GA ranges, along with the corresponding components for the most diverse applications. These pumps also reliably master the most demanding processes in the chemicals, plastics and paints and lacquers industries. They are characterized by low-pulsation feeding of the conveying medium, which promotes more accurate metering.

High-speed pumping despite poor lubrication

One of the greatest challenges here is the highly-accurate metering of poorly-lubricating and abrasive media. The high-speed metering pump was developed especially for this: “It is beneficial above all in cases of chemical manufacturing processes that focus on aggressive acids”, emphasizes Thorsten Wagener, the sales expert responsible for industrial and chemical application pumps.

The main advantage of this high-speed pump is its sealed product space. The space that comes into contact with the media is therefore limited to the area around the gears. This extends the lifespan of the pump considerably.
