Description
Klüber UNISILKON L 250 L Special lubricating grease for drinking water, beverage and heating valves and fittings
- UNISILKON L 250 L is a special lubricant based on silicone oil and PTFE with high thermal stability. UNISILKON L 250 L offers good penetration ability in small lubrication gaps and lube points of difficult access. Owing to its relatively high viscosity, adhesion is improved even in case of unfavourable geometries.
- UNISILKON L 250 L is resistant to cold and hot water, superheated steam up to approx. 130 °C as well as industrial cleaning agents and disinfectants. UNISILKON L 250 L is also resistant to pumpable foodstuffs and beverages like fruit juices, beer or milk products. UNISILKON L 250 L is not resistant to
- organic solvents or strong acid and alkaline solutions.
- UNISILKON L 250 L is NSF H1 registered and therefore complies with FDA 21 CFR § 178.3570. The lubricant was developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of UNISILKON L 250 L can contribute to increase reliability of your production processes.
- We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.
- Temperature range: -45°C to +160°C
- Volume: 500g
- Also available in: Cartridge 500g, Can750 g, Bucket 30kg
Benefits for your application
- Proven effective in valves and fittings as well as adjusting mechanisms in the drinking water, beverage, sanitary and heating sectors
- Certified acc. to international standards for valves and fittings, e.g. DVGW-KTW, WRAS, ACS, AS 4020, NSF Standard 61 and NSF H1
- Long-term protection of seals and bearings owing to the lubricant’s good resistance to numerous media like disinfectants, cleaning agents, water, steam
Applications
- UNISILKON L250L is used as lubricating and sealing grease for:
- domestic valves & fittings for drinking water, (e.g. ceramic discs and piston cartouches, thermo regulators). As the lubricant’s viscosity is rather independent of service temperatures, UNISILKON L250 L allows constant actuating forces within the whole cold/hot water range of e.g. single-lever mixer taps.
- valves and fittings of heating installations (e.g. thermoregulators, tap cocks, pressfit seals)
- UNISILKON L250 L has also proven effective as assembly aid for radial shaft seals and packings in contact with cold or hot water and steam.
Application notes
UNISILKON L 250 L is neutral towards most metals, thermoplastics and elastomers. Owing to the many different elastomer and plastic compositions their compatibility should be checked prior to series applications. UNISILKON L 250 L can be applied by means of spatula, brush, usual metering devices or the tampon printing method. Please observe the material safety data sheet.
