Centrifugal fan mechanical seal issues
Thread Content
Our company is planning to purchase 6 centrifugal fans that will be used in environments with carbon monoxide and hydrogen, and zero leakage is required. Can mechanical seals be used for the sealing of these centrifugal fans?
Mechanical seals are used for ventilators and blowers
Why can’t a mechanical seal be used?
For gases, mechanical seals cannot achieve zero leakage, while dry gas seals can.
Sure, if zero leakage is required, a nitrogen seal can also be added
