Lubricant LEYBONOL

Diffusion pump oil ( Lubricant LEYBONOL)– LVO 500, 521, 540 For diffusion pump oil, the choice of fluids is critical. These fluids need to meet specific criteria to ensure optimal performance, including:

• Low vapor pressure and thermal stability: They maintain low vapor pressure at room temperature while demonstrating significant resistance to thermal decomposition and oxidation.
• High surface tension: The fluids should possess high surface tension characteristics to minimize the creeping of oil films.
• Chemical inertness, high flash point, and low evaporation heat: They must exhibit chemical inertness, boast a high flash point for safety, and have low evaporation heat.
• Versatility and cost-effectiveness: Ideal pump fluids should enable high pumping speeds across a broad pressure range while remaining cost-effective.
