Water purification & sanitation
Our water purification & sanitation
Nova Diamant offers advanced water purification and sanitation services using diamond coating technology to improve the efficiency and sustainability of purification processes. Our diamond-coated components, such as valves and pump seals, are designed to withstand the most demanding conditions, including chemically aggressive and abrasive environments. By using diamond coatings on surfaces that come into contact with water, we reduce the risk of corrosion and wear, which leads to longer life and reduced maintenance.

The absolute most common is to diamond coat silicon carbide. It provides good adhesion and withstands the temperature during diamond growth. Today, it is relatively easy to order details in silicon carbide material. Other materials such as carbide-forming metals (Ti, W, MO) can be coated. Carbide can be coated, but is not something we recommend due to difficulties in obtaining reliable adhesion. Our recommendation is to use sintered silicon carbide.
It differ depending on installation and seal. The best case is a water lubricated/cooled seal where the friction reduction can be 50 % which can save a lot of energy during the service life. If the seal has plenty of oil lubrication that separate the surfaces well, most of the losses are in the viscous drag of the oil – no reduction. Typically the friction reduction is high during sever conditions like start/stop and dry running which keep the temperature down and save seal faces and the secondary seals (o-rings).
Wear resistance increases dramatically compared to a standard ceramic sealing ring.
Yes, but it usually requires a fixture and new set-up (process adjustment), this create an extra initial cost.
