T S Pot is used to circulate barrier fluid in the seal chamber. This can be done at atmospheric pressure or can be pressurized by the hand pump attached to the T S Pot. Selection of barrier fluid depends upon the process, any fluid having lubricating properties can be selected which should be compatible with the process media.
Advantages of using T S Pot:
Lubricates the seal faces
Disperse the heat generated in the seal chamber by syphoning effect
Maintain pressure in the seal chamber to counter the equipment pressure
