The seals are designed to give long life, provide automatic self-adjustment, and reduce maintenance costs. Additionally, mechanical seals offer these important advantages.

Absolute Sealing

Proper selection and installation of seals result 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 the Shaft and Seal Parts

Replace packing with a mechanical seal and avoid expensive shaft or sleeve replacements.

Flexible 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

The seals are designed for higher speeds and pressures.

Flat Surfaces of Mating Faces

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.
