SANTOVAC 5* (CONVALEX-10) VACUUM PUMP FLUID Santovac 5 is a five-ring polyphenyl ether fluid, operates efficiently, economically and safely in diffusion pumps to produce ultra-high vacuums in the 10-10 torr range in properly designed systems. Santovac 5's wide liquid range, low vapor pressure, and the unique balance of properties listed below make it an ideal candidate for your vacuum needs. LOW VAPOR PRESSURE: Extremely low vapor results in low ultimate pressures. Vapor pressure of Santovac 5 at 25oC, (obtained by extrapolation at higher temperature data) is 4x10-10 torr. This means lower ultimate vacuum. LOW BACKSTREAMING: Backstreaming depends on the vapor pressure of the fluids, the system design, operating conditions and the temperature of the collecting surface. Santovac 5 has inherently low backstreaming characteristics -- as low or lower than any other commercially available fluid. The result is less contamination in chambers and longer-term operation for those processes that are sensitive to organic matter. This makes polyphenyl ether type fluids like Santovac 5 well suited for electronic component applications.

SILICONE DIFFUSION PUMP FLUID LDS 704 SPECIFICATIONS: LDS 704 diffusion pump fluid is a single component, colorless fluid for high vacuums of 10-6 torr (untrapped) and 10-8 (trapped). It performs well in tough, rugged applications and offers quick pump-downs, even after exposure to air at operating temperatures. It is thermally and chemically stable allowing it to keep pump jets free of tars and hard carbon. LDS 704 diffusion pump fluid is used to produce high vacuums for aerospace and electronic industries, for metallurgical and research needs and for certain special vacuum coating applications. LDS also has the ability to reclaim this fluid.

LDS 702 SILICONE DIFFUSION PUMP FLUID SPECIFICATIONS: LDS 702 diffusion pump fluid is a water white silicone designed for fast pumping of large volumes of gas or vapor in production operations. It can produce high vacuum in the range of 10-5 to 10-7 torr. LDS 702 resists oxidation at high temperatures to allow immediate vacuum release without pump cooling. Also, it is temperature stable to insure system cleanliness and reduce maintenance. LDS also has the ability to reclaim this fluid.

LDS 705 - SILICONE DIFFUSION PUMP FLUID SPECIFICATIONS: Single-component fluid designed for ultra-high vacuum applications in the range of 10-9 to 10-10 torr (untrapped). The vapor pressure and backstreaming rate of LDS 705 fluid are so low that use of traps or refrigeration is unnecessary for some ultra-high and ultra-clean vacuum applications. Because of its low vapor pressure, contamination rates with LDS 705 can be up to 100 times lower than with LDS diffusion pump fluid.

THE ULTIMATE HYDROCARBON OIL FOR ALL DIRECT DRIVE PUMPS…. LDS ELITE SPECIFICATIONS: GRADE A AND GRADE Z Mechanical Pump Fluids are specially formulated hydrocarbon pump fluids that are far superior to any other hydrocarbon fluid on the market today. They are designed for use over a broad range of performance conditions. They exhibit good resistance to oxidation and provide excellent safety factors with their high flash and fire points. LDS ELITE fluids have excellent lubricity for use in today's high speed, high operating temperature pumps. They do not break down as readily at these temperatures as do other standard hydrocarbons. These fluids offer improved performance at both high and low operating temperatures. In some cases, LDS ELITE will serve as a cost-effective alternative to inert fluids such as Fomblin or Krytox.
