China High Quality John Crane Mechanical Seal Manufacturer – W1A Full Convolution Industrial-duty Elastomer Bellows Shaft Seal replace John crane type 1A mechanical seals – VICTOR SEALS Detail:
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.
