VTECH 702, 704 and 705 Premium Diffusion Pump Fluids are designed for high vacuum and for fast pumping of large volumes of gas or vapor in production operations.
VTECH Diffusion Pump Silicon Fluids offer the following benefits:
-
Shorter conditioning runs: Single-component silicone fluids reach maximum potential in far less time than that required for multi-component organic fluids.
-
Faster pumping: Diffusion pumps using VTECH silicone fluids can operate against 20 to 300 percent higher fore-pressures than those using organic fluids. For higher gas through-put at the high-pressure end of the pump’s operating range, heater input can be increased 20 to 30 percent.
-
Minimal backstreaming: The vapor pressure of VTECH's single-component silicone fluids is so low that the use of traps – or refrigeration of existing traps is unnecessary for many applications.
-
Longer service life: Thermal and chemical stability of VTECH silicone fluids allows exceptionally long runs without deterioration or contamination.
-
Cleaner systems, less maintenance required: Low vapor pressure of VTECH silicone fluids at baffle temperatures results in low migration rates. Jets and boiler surfaces stay clean; silicone fluids exhibit virtually no breakdown or decomposition under operational conditions.
-
Faster cycling, reduced downtime, less frequent fluid replacement: The recovery rate of silicone fluids after exposure to air at operating temperatures is many times faster than that of organic fluids. Time is saved between cycles because of VTECH silicone fluids' outstanding resistance to oxidation and hydrolysis which allows release of the vacuum without cooling the pump.
