U.S. Seal Mfg. offers a complete
line of quality seals for your replacement needs.
As most engineers know, a successful seal must be designed to give long life, r
educe maintenance and provide automatic self-adjustment. The seals in the U.S.
Seal line meet these basic requirements. In addition, they offer other important
advantages to the seal user.
- ABSOLUTE SEALING. Resulting in
less pumpage loss, cleaner facility environment, reduced fire hazard, no
danger from fumes and no contamination of the fluid being handled.
- NO RUBBING FRICTION BETWEEN SHAFT AND
SEAL PARTS. Eliminate expensive shaft and sleeve replacement by
replacing your old packing with new state-of-the-art U.S. Seal
- GREATER FLEXIBILITY OF SEALS MEANS
LONGER SERVICE LIFE. Seals have more flexibility than packing and
are able to compensate for shaft whip, axial and radial end play, as
well as vibration and wear of the sealing faces.
- LESS FRICTION MEANS VALUABLE POWER
SAVINGS. Seals create less friction than packing and therefore
require less horsepower.
- PRECISION LAPPED SEALING SURFACES.
Positively control leakage and eliminate "break in" runs.
- HIGHER SPEEDS AND PRESSURES ARE NOT A
- POSITIVELY DRIVEN MECHANICAL SEALS.
- EXTREME 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
- MATERIALS OF CONSTRUCTION. TFE,
AFLAS®, EPR and VITON® materials are available for
those applications where NEOPRENE and BUNA are not compatible with the
process fluid. Metal parts are normally made of brass, plated steel or
stainless steel, but other alloys, such as Monel® or
Hastelloy® can be supplied. Seat materials are available in a
