Comunicados de prensa () Oerlikon Balzers introduces new coating portfolio to extend service life of sanitary fittings and pumps
Balzers, Liechtenstein, 12 June 2019 – Ceramic seal discs in sanitary fittings, pneumatic valves, ceramic shafts and pump bearings as well as components in pumps and compressors are exposed to extreme friction over a long period of time. To keep these devices running reliably for longer, leading surface solutions provider Oerlikon Balzers has developed BALINIT MILUBIA and BALINIT NALUBIA; hydrogen-free hard carbon coatings that protect components against wear from frequent use and at elevated temperatures.
Both coatings are characterised by very low coefficients of friction, and the low coating temperature means that they can also be applied to heat-sensitive materials.
BALINIT MILUBIA for extreme friction
BALINIT MILUBIA has been specially developed for sealing discs, pneumatic valves, ceramic shafts and pump bearings. The microstructure-based coating provides a hardness of 35 to 40 HIT(GPa). BALINIT MILUBIA is suitable for metals and electrically insulating materials such as ceramics and even plastics. The coating ensures a low operating force on ceramic seal discs even when the assembly grease is washed out after a long period of use, and the low friction keeps the temperature of sealing rings and discs low even when running dry.
BALINIT NALUBIA – even harder with better ductility
Mechanical seals in pumps and compressors use silicon carbide ceramics as seal ring materials. Oerlikon Balzers has introduced BALINIT NALUBIA, which minimises wear in these components by eliminating poor lubricating conditions that cause increased temperatures. BALINIT NALUBIA offers a coating hardness of 40 to 50 HIT(GPa), and improves component ductility. This effective protection against overheating – even under dry running conditions – significantly extends the service life of these devices.
Extended service life: ceramic seal discs in sanitary fittings coated with BALINIT MILUBIA ensure a low operating force even when assembly grease is washed out after a long period of use.
