Product Advantages
The SPGW combined seal from Forever Seals boasts exceptional advantages. It features low static and dynamic friction coefficients, minimizing wear and ensuring smooth operation without crawling during startup. With a simple groove design, it can adapt to relatively large extrusion gaps, performing reliably even in media containing contaminants, thus guaranteeing a long service life. Its excellent static and dynamic sealing performance makes it a top choice for various demanding applications.
Product Principle
The SPGW combined seal operates on a synergistic mechanism: the PTFE sealing ring, with its low friction and wear-resistant properties, forms the primary sealing interface, ensuring tight contact with the mating surface. The rubber O-ring, acting as an energizer, exerts continuous pressure on the PTFE ring, compensating for wear and maintaining sealing integrity even under varying pressures and temperatures. The POM or PA backup rings prevent extrusion of the sealing components under high pressure, enhancing the seal's stability and durability across diverse operating conditions.
Product Details
Constructed with high-quality materials, the SPGW combined seal by Forever Seals consists of a PTFE sealing ring, which offers superior wear resistance and a low friction coefficient, an O-ring (available in NBR or FKM) that provides the necessary sealing force, and backup rings made of POM or PA for added stability. This combination ensures the seal can withstand working pressures up to 50MPa, reciprocating speeds up to 1.5m/s, and a wide temperature range from -40℃ to +160℃, depending on the rubber components.
Application Range
Forever Seals' SPGW combined seal is widely applicable in long-stroke, high-temperature, and high-pressure scenarios. It excels in heavy-duty double-acting piston sealing applications, such as in excavators, heavy-duty cylinders, and other construction machinery's cylinder piston sealing systems. It is also suitable for hydraulic cylinders in various industrial equipment that require reliable sealing performance.
FAQ
Q: What is the maximum working pressure the SPGW combined seal can handle?
