Supplying a Complete Line of Quality Seals - U.S. Seal Mfg.

U.S. SEAL MFG.Quality Mechanical SealsOur seals are designed to give long life, provide automatic self-adjustmentand reduce maintenance costs. Additionally, mechanical seals offer theseimportant advantages.ABSOLUTE SEALINGProper selection and installation of our seals results in less pumpage loss,cleaner facilities, less fire hazard, no danger from fumes and no contaminationof the fluid being pumped.NO RUBBING FRICTION BETWEEN SHAFT AND SEAL PARTSReplace packing with a mechanical seal and avoid expensive shaft or sleevereplacements.FLEXIBLE SEALS MEANS LONGER SERVICE LIFECompared to packing, mechanical seals are more flexible, and are able tocompensate for shaft deflection, axial and radial end play, vibration and sealface wear.LESS FRICTION MEANS VALUABLE POWER SAVINGSMechanical seals use less friction than packing. Therefore, they require lesshorsepower consumption.PRECISION LAPPED SEALING SURFACESPositively control leakage and eliminate “break in” runs.HIGHER SPEEDS AND PRESSURESOur seals are designed for higher speeds and pressures.FLAT SURFACES OF MATING FACESSealing surfaces are precision lapped to a flatness of one to three lightbands, which maintains the necessary face film lubrication, resulting inpositive leakage control.BROAD SELECTION OF MATERIALS OF CONSTRUCTIONOur seals come in a wide variety of materials. Choose the correctcombination of elastomer, metallurgy and sealing faces for your application.See pages 137-141 for the Material Recommendation Chart.MECHANICAL SEALS CAN BE FOUND IN …• Centrifugal Pumps • Pool and Spa Pumps• Compressors • Progressive Cavity Pumps• Gear Boxes • Rotary Lobe Pumps• Gear Pumps • Slurry Pumps• Jet Pumps • Submersible Pumps• Petrochemical Pumps • Turbine Pumps2
