Type W1 Elastomer Bellows Shaft Seal For Pump Replaced John Crane Type 1 Mechanical Seals

Replacement of Below Mechanical Seals

Burgmann MG901, John crane Type 1, AES P05U, Flowserve 51, Vulcan A5

Technical Features

• Unbalanced
• Single Spring
• Bi-directional
• Elastomer Bellows
• Set screw lock collars available

Designed Features

• To absorb both breakout and running torque, the seal is designed with a drive band and drive notches that eliminate overstressing of bellows. Slippage is eliminated, protecting the shaft and sleeve from wear and scoring.
• Automatic adjustment compensates for abnormal shaft-end play, run-out, primary ring wear and equipment tolerances. Uniform spring pressure compensates for axial and radial shaft movement.
• Special balancing accommodates higher-pressure applications, greater operating speeds and lower wear.
• Non-clogging, single-coil spring allows for greater dependability than multiple spring designs. Will not run foul due to fluid contact.
• Low drive torque improves performance and reliability.
