Spring Energized Face Seal

Working principle overview:

The spring energy storage ring is a high-performance seal with corrosion resistant metal energy storage spring inside and fluorine containing engineering plastic jacket outside. The sealing ring is installed in the sealing groove. The permanent elasticity of the sealing jacket due to the compression of the spring plus the system pressure makes the sealing lip close to the sealing surface of the groove, thus forming an excellent sealing effect. The spring can provide permanent elastic force and vibration compensation effect for the seal jacket, so as to compensate for the wear of the sealing lip and the slight eccentricity of the part fitting, and can maintain a good sealing effect under high pressure or low pressure.

Performance advantages：

The spring energy storage seal ring is a special seal developed for the application environment of high temperature corrosion, ultra-low temperature, no lubrication and low friction. The combination of fluorine-containing engineering plastic composites with different formulas, advanced engineering plastics and corrosive metal springs can completely meet the increasingly demanding working requirements in industry. In addition to sealing applications in high-temperature corrosive environments, its sealing lip can also be used in reciprocating and high-speed rotating conditions because of its low friction coefficient, stable sealing contact pressure, excellent pressure resistance, and large radial deflection tolerance; Compared with rubber products, spring energy storage ring has better sealing performance and service life.
