Frequently Asked Questions
What materials are available for the static and dynamic rings?
Both the static ring and dynamic ring are available in three material options: graphite, silicon carbide (SiC), and tungsten carbide (TC). The choice depends on the specific medium and operating conditions of your application.
What types of media is this mechanical seal suitable for?
This seal is designed for water, sewage, oil, and other weakly corrosive liquids. It is widely used in pumps and rotating equipment handling these common industrial and municipal media.
What auxiliary sealing materials are available?
Three options are available for auxiliary sealing: Nitrile rubber (NBR), Ethylene rubber (EPDM), and Fluororubber (FKM/Viton). Fluororubber is recommended for higher-temperature or chemically aggressive applications.
Can this seal handle high temperature and high pressure conditions?
Yes. Thanks to its strong adaptability, this mechanical seal can be applied across various demanding working conditions including high temperature, high pressure, and high-speed rotation, making it suitable for a wide range of industrial scenarios.
How does the spring mechanism contribute to sealing performance?
A spring installed between the moving ring and the stationary ring continuously applies axial pressure to maintain consistent contact between the sealing faces. This ensures a stable and reliable seal throughout the full operating lifecycle of the equipment.
How easy is it to replace or maintain this mechanical seal?
The seal is designed with a simple structure that allows for straightforward disassembly and replacement. This reduces downtime and lowers the overall maintenance cost of the equipment it is installed in.
