U.S. SEAL MFG.
QUALITY MECHANICAL SEALS
Our seals are designed to give long life, provide automatic selfadjustment and reduce maintenance costs. Additionally, mechanical seals offer these important advantages.
|
|
- ABSOLUTE SEALING
Proper selection and installation of our seals results in less pumpage loss, cleaner facilities, less fire hazard, no danger from fumes and no contamination of the fluid being pumped.
- NO RUBBING FRICTION BETWEEN SHAFT AND SEAL PARTS
Replace packing with a mechanical seal and avoid expensive shaft or sleeve replacements.
- GREATER FLEXIBILITY OF SEALS MEANS LONGER SERVICE LIFE
Compared to packing, mechanical seals are more flexible, and are able to compensate for shaft deflection, axial and radial end play, vibration and seal face wear.
- LESS FRICTION MEANS VALUABLE POWER SAVINGS
Mechanical seals use less friction than packing. Therefore, they require less horsepower consumption.
- PRECISION LAPPED SEALING SURFACES
Positively control leakage and eliminate "break in" runs.
- HIGHER SPEEDS AND PRESSURES ARE NOT A PROBLEM
Our seals are designed for higher speeds and pressures.
- POSITIVELY DRIVEN MECHANICAL SEALS
Sealing surfaces are precision lapped to a flatness of one to three light bands, which maintains the necessary face film lubrication, resulting in positive leakage control.
- FLAT SURFACES OF MATING FACES
Care is taken to furnish precision lapped sealing surfaces with a flatness within three light bands maintaining the necessary face film lubrication.
- BROAD SELECTION OF MATERIALS OF CONSTRUCTION
Our seals come in a wide variety of materials. Choose the correct combination of elastomer, metallurgy and sealing faces for your application. See pages 106-110 of our catalog for the Material Recommendation Chart.
