Looking for manufacturers of packing seals for stirred-tank reactors
Thread Content
The unit has a reactor in which the medium consists of hydrogen and sodium; the maximum operating pressure inside the reactor is 1.5 MPa. Currently, a magnetic stirrer mechanical seal is being used, but after just half a month of operation, this seal wears out and starts to leak, and the cost of repairing it is very high. We are considering switching to a packing seal, and we are looking for a reliable manufacturer to develop a solution for this.
Mechanical seals should be better than packing seals, I’m also waiting for an answer.
Mechanical seals have good performance, which is why they are more expensive
With this pressure, a packing seal cannot hold it back. I don’t understand what a \"magnetic stirring mechanical seal\" is. Under normal circumstances, magnetic stirring does not require a mechanical seal; it would be best to take a picture and show it. I don’t know what the temperature is, but a mechanical seal rated for 1.5 MPa should work fine. It’s abnormal for it to break down every half month.
Can magnetic stirring also cause leaks? Static seal!
Check the material of the rotating and stationary rings, whether the mechanical seal has a cooling system (water, air), and whether it is a dry seal or an oil seal; mechanical seals are not supposed to break down easily.
The seal for magnetic stirring should not have moving or stationary rings, similar to the drive mechanism of magnetic pumps
