The reaction kettle is filled with sodium carbonate and alcohol solution. What lubricating oil is used for the bearings of the magnetic transmission?
Thread Content
We have a reaction kettle here. The main media in the kettle are sodium carbonate and alcohol, and the temperature is around 120°C.； ； The magnetic transmission type used in the reactor, the ball bearing under the internal magnet (upper end of the coupling), is often worn. The inspection revealed that the lubricating oil had been dissolved, and the 2# high-temperature lithium-based grease was now used. . . . . . Please give me some advice as to what grease should be used in this situation.

There is a sliding bearing in the middle, made of pure graphite, which seems to be not stiff enough.
Is it possible to use a double diaphragm pump?
