Are individuals familiar with OmniSeal® polymer spring-energized seals and rotary lip seals? Have they ever wondered why spring-energized seals have a spring and jacket while lip seals have a metal casing? How do these two unique designs benefit an application? Lifetime confidence is considered to be just one of the main benefits; given below are a lot more reasons why OmniSeal® parts should be the seal of choice.
Failure or function? Compromise or confidence? Which of these traits best describe an individual’s sealing solutions? Saint-Gobain Seals believe critical parts demand critical precision that can only be attained through expert material formulation, manufacturing, engineering and testing with the end result instilling lifetime confidence. Here’s how:
Formulated to Solve Problems
OmniSeal® PTFE rotary lip seals are driven to solve the toughest sealing challenges; they are always co-designed with customer input in order to meet unique specifications. The metal casing design is considered to be a distinctive sealing solution that bridges the gap between standard elastomer lip seals and expensive mechanical face seals. Unlike standard designs, the rotary lip seal overcomes challenges such as speeds, temperatures and pressures in order to provide engineers with a cost- effective sealing solution that does not compromise on performance for dynamic applications.
Engineered for Cost Savings
OmniSeal® spring-energized seals broke the manufacturing mold (so to speak) by being among the first seals where the fluoropolymer-based jacket of the seal was injection molded, unlike standard materials which were completely machined. With a molded solution, there is the potential to save significantly over machining, which can be a great advantage in the total cost value of building assemblies.
Manufactured and tested for precision
Our OmniSeal® spring-energized seals integrate a spring- actuated, pressure-assisted sealing device constructed of a PTFE (or other polymer) jacket that is partly encapsulated by a corrosion-resistant metal spring energizer.
To manufacture these unique devices, a special assembly line fitted with unique cutting tools was built. These manufacturing tools allow for an extensive variety of part geometries. All manufacturing is carried out in-house within the global manufacturing facilities and parts are tested for lifetime confidence and critical performance. The company also invests heavily in its R&D for improved simulation tools such as finite element analysis (FEA) to model, design and then validate complex designs in order to confirm that they meet the specifications.
Application Versatility for Best Results
The OmniSeal® products are a perfect solution for extreme applications where high load, low friction and extreme temperatures are a concern. Design versatility including sealing jacket with several spring types to 2- or 3-lip designs that meet the demanding application requirements offer customized solution for various needs. Given that sealing solutions often control the fundamental functioning of a system, prolonged life means that failure is not an option.
Where can Users Find OmniSeal® Spring-Energized Seals and Rotary Lip Seals?
First designed in the 1950s and employed for a number of space programs, the OmniSeal® spring-energized seals really brought about a difference with NASA’s Space Transportation System when the first space shuttle was launched in 1981. Since then, the company has worked with hundreds of engineers from NASA and various other key space visionary companies to design and then manufacture thousands of seals in the life support systems, external tanks, main engine and launch vehicles.
The seals are presently used to solve pressure, temperature and weight requirements of jet and helicopter engine seals, rotors, gearboxes and hydraulic/pneumatic controls. Customers can explore the space solutions or check out other space journeys.
After being established in aerospace, OmniSeal® products have since then excelled in other industries as well.
In automotive powertrain and transmission, OmniSeal® seals enable the reduction of friction and CO2 emissions in order to deliver a more energy- efficient solution. Just as in the aerospace market, they are also capable of delivering a better weight-to-performance ratio for better fuel savings using the precision control capability. They can be identified in fuel injection pumps and engine shaft seals.
In Energy/Oil and Gas:
In this hazardous and extreme field, OmniSeal® sealing parts are extremely valuable. The material helps solving the reliability problems that can take place when elastomer seals come in contact with corrosive oil and gas (or sour gas), plus differing pressure and temperature requirements and sudden high-pressure changes. Individuals can look for them in temperature ranges from cryogenic to 300 °F and above and pressure conditions up to 20,000 psi.
