DuraClear Crystal 7 Seal Lubricant is a premium barrier fluid for use on equipment handling high purity, high value or highly reactive product fluids such as strong acids and bases. It has been specifically formulated for the lubrication needs of dual mechanical seals. When chemical compatibility is critical, this environmentally friendly and nonreactive barrier fluid extends the life of dual mechanical seals for increased process yield and throughput.

Why use DuraClear?

  • Lower energy consumption by 25%
  • Up to 8x longer life compared to mineral oil
  • Longer seal life due to reduced friction and wear
  • Wider operating temperature range than non-synthetic fluids
  • Less pollution at disposal time versus hydrocarbon based products
  • Indefinite shelf life
  • Higher quality lubricant provides better load support
  • More stable viscosity at all operating temperatures
  • Higher temperatures than non-synthetic fluids
  • Environmentally friendly during installation, operation and disposal.
  • Benchmark tested against 40 other options
  • DuraClear is compatible with all seal face materials
  • Extremely inert DuraClear 7 maximizes compatibility with sensitive and reactive process fluids
  • Food grade

 

Benefits:

  • Chemically compatible with nearly every possible fluid –
  • Will not coke, crystallize, plate out, or otherwise negatively impact the seal’s ability to perform over time
  • Eliminates carbon blistering
  • Environmentally friendly during installation, operation, and disposal
  • Will not change the performance of the process fluid
  • Will not discolour the process fluid
  • Can be readily separated from the process fluid

DuraClear Crystal 7 is better than CTFE oils in every way:

  • Better compatibility with Lewis acids
  • Better lubrication capability (lower seal face wear)
  • More thermally stable
  • No corrosive Chlorine in molecular chain
  • Significantly higher viscosity index
  • Competitive price
  • Safer to handle

Where should it be used?

– When compatibility with the process fluid is critical

  • Harsh chemicals – Acids
  • Sulfuric acid
  • Nitric acid
  • Hydrofluoric acid
  • Hydrochloric acid – Bases – Chlorine – Solvents – Strong oxidizers – Caustic
  • High purity fluids

Operating Temperatures:

 

  • CTFE fluids may react violently with K, Na, amine, hydrazine, liquid fluorine, liquid chlorine trifluoride, Aluminum, Aluminum Chloride (AlCl3) and Aluminum Oxide (Al2O3)
  • DuraClear Crystal 7 has a higher reaction temperature than CTFE with all of these substances
  • Greater than 288°C (550°F)
