How to Choose Sealing for Reactor：

1. Packing seal is usually used when reactor is under of atmospheric pressure or low pressure. Generally, the pressure is less than 2 kg.

2. Mechanical seal will be used when reactor is in general conditions of medium pressure or vacuum pumping, and the general pressure is negative pressure or 4 kg.

3. Magnetic seal will be used when reactor is under high pressure or high volatility of medium. The general pressure is over 14 kg. Water cooling is used in all magnetic seals except water cooling, the cooling water jacket will be added in other seal forms above 120 degrees.
