Saint- Gobain Seals Group's OmniSeal spring-energized seal has been qualified as a dynamic seal in chemical injection pumps for the oil and gas industry.

These pumps are used in pipe-line injection systems and also in oil wells and natural gas production and transportation.

The OmniSeal spring-energized seal is a custom version of the Seals Group's APS seal, Saint-Gobain said. The seal utilizes an APS type spring and polymer jacket and seals against plunger shafts ranging from one-fourth of an inch to a half-inch in diameter. The shaft speed moves up to 16 strokes per minute and one inch in stroke length.

The benefits of the seal include large wear allowance in the seal jacket, installation in closed glands without damaging the seal and high-performance when low friction in dynamic conditions is required.
