1, first cooling the form of export or high-pressure side of the pump will transport clean media, direct flush seal faces, and then into the pump chamber, through the continuous cycle of the media, the friction of the friction face tropical go to achieve the cooling effect.

2, the second cooling mode
Increase a cooling water jacket in the back of the stationary ring forms the basis of the first cooling, the cooling effect is improved, and you can wash, collect the leaked liquid. When the sealing medium temperature> 150 ℃ in the cooling water jacket through cooling water and the stationary ring back cooling, forced cooling measures should be taken. Clean medium from the pump outlet should be pre-cooled by the heat exchanger to 50 ℃. Re-enter the sealed chamber cooling flush, the form of a cooling effect.

3, such as media containing particles or impurities, filtration measures, at room temperature a clean wash liquid to enter the sealed cavity.
