Technical Paper: High-performance carbon – the service life extender for pumps

Thursday, July 19th, 2018 von admin

Slides assume the main job of generating the vacuum – more than 30,000 hours of durability were achieved using a new material

Whether slide bearings, sliders or mechanical seals – all these components are exposed to high loads on a daily basis and, therefore, wear out. With innovative materials, however, maintenance intervals and the service life of pumps and seals can be extended considerably, as evidenced by developments in carbon materials.

Selecting the right material determines the service life of machines, units, and systems. Conventional materials often reach their load capacity limits, especially in pumps and mechanical seals. Schunk Carbon Technology develops and produces materials for seal rings, slide bearings, and pump components made of carbon and silicon carbide. These innovative materials particularly excel in the areas of abrasion resistance, sliding capability, media resistance, and temperature resistance. Carbon in the form of graphite also has the characteristic property of self-lubrication. All in all, exactly the features required in demanding industrial environments. “In practice, their use leads to a significant increase in service life and extended service intervals,” says Thomas Kräuter, Sales Director of the Mechanical Carbon Industry at Schunk. It is not enough to simply replace a material; many years of expertise are required. Three current development projects demonstrate the path from material to functioning components, leading to new materials that considerably extend the service life of pumps, seals and the like.
