A vacuum pump package for Carbolite Gero tube furnaces consists of a vacuum pump, flowmeter for inert gas, vacuum gauge, vacuum tight valve, bypass for fast purging, gas outlet valve and safety overpressure valve.
Combine a vacuum pump package with a vacuum work tube package and a Carbolite Gero tube furnace to create a complete system for your vacuum applications. Includes an inert gas package for backfilling with an inert gas.
Carbolite Gero offers two different vacuum pump options for tube furnaces, rotary vane pump and turbomolecular pump.
TURBOMOLECULAR VACUUM PUMP PACKAGE FOR TUBE FURNACES
The turbomolecular pump consists of stators between several high-speed rotors. The rotational speed is about 90,000 revolutions per minute. At these speeds, the rotor is now in the range of the particle velocity, enabling gas to be pushed through the pump. The achievable vacuum level is higher or better when combined with a pre-vacuum pump.
Turbomolecular pumps are the most convenient and frequently used for high and ultra-high vacuum operations. Very high atmospheric purity of the furnace chamber is achieved as the pump easily removes heavy, slow particles, such as hydrocarbons.
Carbolite Gero’s turbopump version consists of a vacuum pump, inert gas package, vacuum gauge, tight vacuum valve, bypass for fast purging, gas outlet valve and safety overpressure valve. In a cold, clean, dry and empty furnace, the turbo pump option reaches 5 x 10-5 mbar.
STANDARD FEATURES
- Turbo pump with a pumping rate of 65 l/s
- Rotary vane pump as pre-pump
- Full-range vacuum gauge
- Vacuum tight valve
- Choice of flowmeter for either nitrogen or argon
- Bypass for fast purging
- Gas outlet valve
- Safety overpressure valve
ROTARY VANE VACUUM PUMP PACKAGE FOR TUBE FURNACES
The rotary vane pump is a pre-vacuum pump and is the most frequently used pump. The pump directly evacuates atmospheric pressure with a rotating speed of approximately 1,500 turns per minute via a radial, movable plug. The vacuum chamber of the pump is greased with oil.
Carbolite Gero’s rotary pump consists of a vacuum pump, inert gas package, vacuum gauge, tight vacuum valve, bypass for fast purging, gas outlet valve and safety overpressure valve. In a cold, clean, dry and empty furnace, the rotary pump option can reach a vacuum level of 5 x 10-2 mbar.
STANDARD FEATURES
- Double-stage rotary vane pump with a pumping rate of 4 m3/h
- Pirani gauge
- Vacuum tight valve
- Choice of flowmeter for either nitrogen or argon
- Bypass for fast purging
- Gas outlet valve
- Safety overpressure valve
