1A Mechanical Seal

Benefits of an A1 Mechanical Seal

Self-aligning: Automatic adjustment compensates for abnormal shaft end play, run out, primary sealing wear and machinery tolerances leading to  improved service life.
Mechanical Drive: The drive ring’s notch design eliminates extra stress of the bellows
Non-clogging Single Coil Spring: Provides greater dependability than multiple designs.
Special Balancing: For higher pressure applications, greater operating speeds & lower wear.
