Alabaster, AL 35007 Email: sales@sepcoUSA.com Website: www.sepcoUSA.com The SEPCO® HOS is a rotary designed, balanced, single spring seal capable of handling higher operating pressures and temperatures than conventional unbalanced single spring designs. Large coil springs are resistant to clogging and allow the HOS to operate successfully in hot oil applications. The seal is available for fitting both standard and oversized seal cavities. OPERATING CAPABILITIES: Pressures: Temperatures: Speeds: Metal Parts: Rotary Face: Carbon Graphite or Solid Nickel Bound Tungsten Carbide Secondary Seals: Viton, Aflas and Kalrez 7075 Fits Narrow Stuffing Boxes Seal sizes 1” through 1-3/8” (inclusive) require a 5/16” cross section, and sizes 1-1/2” through 2-5/8” (inclusive) require a 3/8” cross section. Slotted Glands The HOS design features a slotted gland that offers more versatility with bolting patterns. Impeller Adjustments In Service Disassembling the pump is unnecessary to make impeller clearance adjustments. Cartridge Mounted The seal is pre-assembled at the factory, mounted on its sleeve and installed in the gland for easy installation. No Installation Measurements Mechanics are not required to make critical installation measurements in order to install the seal.
