Products Description
Compared with single-end mechanical seal, double-end mechanical seal has good sealing performance and is suitable for sealing under the conditions of strong corrosion, high temperature, with suspended particles and fiber medium, gas medium, inflammable and explosive, volatile low viscosity medium and high vacuum.


Housing: Stainless steel
Product-wetted parts: SS304, SS316, Hastelloy, Titanium, other special materials
Seal rings: Carbon, Silicon Carbide, Tungsten Carbide etc.
O-rings: FKM , EPDM, FFKM etc.

Applications Scenario

Application equipment :Nutsche Filter Dryer,Reactor, All kinds of Dryer and Crystallzing equipment.Application industry:It is widely applied in the industries, such as pharmaceutical, chemical engineering, agrochemical, food, etc.
Pharmaceutical industry
Chemical engineering
Agrochemical industry
Food industry

Main Characteristics

➤Low end temperature:Good heat resistance,if we use back cooling, the temperature will be even lower
➤Low cooling water consumption:Cooling water is only used for back cooling, which is significantly lower than the original cooling water consumption on site
➤Good sealing effect:Double-end mechanical seal has two seals. If the first seal fails, the second seal can still be sealed to prevent leakage
➤Small end wear and long service life:Through the analysis and study of the sealing dynamic and static ring after continuous operation, the end face of non-contact dynamic and static ring is almost not worn, the wear of contact end face is greatly reduced compared with the original sealing end face, and the hot crack does not occur, and the service life is greatly extended
