Solutions— especially for extreme applications.

wear protection for pumps valves and compressors

Especially in pump, valve and compressor construction, parts and components made of cemented carbide create added value. The same applies to sealing technology. The reason for this: In production areas where things get extreme, the use of cemented carbide is much more efficient against premature wear—and optimizes the production.

WE SOLVE WEAR PROBLEMS

Valves, pumps and fittings are often exposed to abrasive media such as quartz, sand, salt or other extreme conditions. For applications in which corrosion protection is important, DURIT offers a range of successful carbide grades with chrome-nickel binders. Special grades of carbide significantly increase the service lives of the respective components.
