I would like to ask everyone: can a bellows mechanical seal be used on the pump that transports Carbon 5?
Welded metal bellows tend to suffer from fatigue failure in media such as liquefied gas; therefore, they are not recommended for use in pumps handling liquefied gas and similar light hydrocarbons that evaporate rapidly.
The auxiliary O-ring of the moving ring tends to swell under C5 conditions, so using a bellows is a better choice.
The products manufactured by our company are mainly designed for gasoline, diesel, carbon-9, carbon-5, and other light-duty fluids. We have always used multi-spring mechanical seals, with the spring O-rings typically made of fluororubber or polytetrafluoroethylene. Sometimes customers request custom-made bellows-type mechanical seals, in which case it is essential to choose the right material for the O-rings
It can be used; it’s better than spring-sealed ones, but it’s more expensive
