Double face mechanical seals are designed to ensure that mechanical seals can work in a maximum sealing mode. Double face mechanical seals virtually remove leakage of the fluid or gas in pumps or mixers. Double mechanical seals provide a level of safety and minimize pump emission compliance not possible with single seals.It is essential to pump or mix a dangerous or toxic substance.
Double mechanical seals are mostly used in flammable, explosive, toxic, granular and lubricating medium. When it is used, it needs a sealing auxiliary system, that is, the isolation fluid is inserted in the sealing cavity between the two ends, thereby improving the lubrication and cooling conditions of the mechanical seal. The pump products that use double mechanical seal are: fluorine plastic centrifugal pump or IH stainless steel chemical pump, etc.
