SES 500 Series

High‑performance, multi‑purpose stacked V‑Ring sets are ideal for demanding applications where reliability and seal performance are required. The 500 Series can accommodate hardware with deep stuffing boxes. These stacked sets are used in both rotary and reciprocating applications and are available in solid and split designs, depending on application requirements.

A typical 500 Series V‑Ring set is comprised of female and male gland adapters (for supporting and energizing functions) and three to five sealing rings, depending on operating conditions and equipment hardware configuration. The gland pressure (energizing axial force) is transferred between the seal rings, pressurizing them and creating optimal, positive contact with the counter surfaces.

Other 500 Series sets incorporate a gland adapter ring, several seal rings (V‑Rings), and a radial Spring Energized Seal (SES) ring. The radial SES ring is the primary sealing element. When pressurized by the system pressure, it activates the V‑Rings by pushing against the gland adapter ring. The multiple seal edges reduce the risk of potential leak paths, while the gland adapter ring provides support to the entire seal set and protects against extrusion.

The 500 Series is available in several unique materials to address a broad range of applications where chemical compatibility with media, high or low operating temperature, or high speed (fast reciprocating movements) make the application challenging for the seals.
