US Seal PS-204 Type E 1.125″ Pump Seal Assembly

Description

Seal Size (in): 1.125

Features

• Aftermarket Industry Standard
• Equal to: John Crane Type 1
• Self-adjusting elastomer bellows compensate for abnormal shaft end play and primary face sealing wear.
• Effects of radial and axial shaft end play are minimized by uniform spring pressure.
• Positive drive is transmitted through the drive band and drive notches, which absorb breakout and running torque.
• Damaging stresses on the elastomer below are prevented.
• Slippage is eliminated, thus protecting the shaft and sleeve against wear and scoring.
• The result is a long seal life.
• The seal’s large single-coil spring is much sturdier than a multiple-spring construction design.
• The spring is non-clogging, self-cleaning, and will not foul up due to fluid contact.
• Corrosion and clogging problems are eliminated.
• Cup Mounted Mating ring

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.
