Ceramdisc® seal and regulator discs

Ceramic Discs for the perfect Sanitary Fitting Seal

Annually, more than 50 million of our Ceramdisc® ceramic discs are installed as seal or regulator discs in sanitary fittings.

Behind this success are CeramTec’s carefully selected ceramics, optimized and proven through years of use, which uncompromisingly meet the demands of sanitary fittings in terms of the sealing power of the discs, hardness and reliability for single-handle mixers and mixing cartridges.

Ceramic seal discs, regulator discs and diverters are manufactured from alumina ceramics using a state-of-the-art method, which results in sliding surfaces with extraordinary, diamond-like hardness. They also offer outstanding chemical resistance against acids and alkaline solutions. These sliding surface properties ensure the superior reliability and long service life of Ceramdisc® seal and regulator discs. Solids carried in drinking water such as sand, rust, and lime are ground between the sliding surfaces of the ceramic discs without impacting the sealing power of the sanitary fittings. And this performance lasts to ensure exceptionally long service life. Even after millions of motion cycles they show no signs of wear and continue to precisely control the desired amount and temperature of the water in sanitary fittings – despite tough conditions such as fluctuating pressure ratios and water temperatures in the supply system.

Ceramdisc® Seal and Regulator Discs for Single-handle Mixers and Mixing Units

Ceramdisc<sup>®</sup> Seal and Regulator Discs for Single-handle Mixers and Mixing Units

A successful system, proven millions of times over: The assembly consisting of two Ceramdisc® ceramic discs delivers reliability, long life and superb precision in controlling the amount and temperature of the water in single-handle mixers and mixing units.

CeramTec has an extensive portfolio of disc geometries and designs depending on the construction of the cartridge used and the desired flow properties. It is also possible to develop customer-specific seal and regulator discs with optimized designs – CeramTec takes a wide range of criteria into consideration here, including:

  • Comfort and convenience of the cartridge
  • Noise suppression in the cartridge
  • Cartridge flow rate
  • Reduced contact surfaces of the tribological pairing
  • Hydraulically optimized connections
  • Tight tolerances

Ceramdisc® Seal and Regulator Discs for Two-Handle Faucets

Ceramic seals made from Ceramdisc® discs offer a number of advantages and have nearly completely replaced conventional seals in two-handle faucets as well. Precisely ground and polished ceramic discs ensure astoundingly long life, optimum sealing power and matchless operating comfort for two-handle faucets. Two-handle faucets mix warm and cold water directly in the faucet instead of in a cartridge.
