Use Cases
Addressing Challenges in the Fuel Cycle
Challenge
Solution
-
Oil-contaminated exhaust gases require costly treatment and maintenance.
An oil-free design eliminates concerns about contamination from rotary vane pumps.
-
Tritium leakage must be minimized as much as possible.
Helium leak rates are as low as 1×10−9 - 1×10−8 Pa·m³/s. Models with integrated helium leak detection sensors are also available.
-
Limited installation space requires equipment to perform multiple functions.
Can be used for vacuum pumping, circulation, and compression, enabling efficient operation with a compact footprint.
Key Attributes
Built for Tritium Service
-
All-metal construction prevents gas from leaking to the outside. (Helium leak rate 1×10−9 - 1×10−8 Pa·m³/s)
-
The bellows and reed valves that contact the gas do not wear, and do not contaminate the fuel gas.
-
Stainless steel is used. The gaskets are aluminum O-rings, for an all-metal seal design..
-
The design keeps operating stress below the fatigue limit of the materials, so performance is maintained over a long service life.
-
Explosion-proof motors, variable-speed drives, special voltages, double bellows, and alternative gasket materials are available.
