Spring Energized Seals

Spring Energized Seals

Chesterton offers the latest version of spring energized polymeric seals. Spring energized seals typically consist of a polymer jacket and a metallic spring. The spring provides a consistent load throughout the circumference of the seal and creates a leak-tight seal between the jacket and the hardware. In addition, the system pressure creates an additional sealing force between the jacket and the hardware. In this combination, the spring forces the seal lips against the gland and rod surfaces while pressure assists the spring force.

Spring energized seals are applied in numerous industries across a wide array of applications that include compressors, valves, pumps, dispensers, instrumentation, swivel joints, actuators, vessels, formed seals, injection molders and screw feeders to name a few.

In addition to standard designs, special seals can be engineered and produced within a very short period of time to meet specific customer requirements within the following criteria:

Temperatures from – 253 °C to 315 °C (-425°F to 600°F)
Pressures from vacuum (10-8 Torr) to 414 MPa (60,000 psi)
Surface speed up to 25 m/sec (5000 ft/min)
Diameters up to 2159 mm (85 inches)
