63A/66A-Heavy Duty Stationary

The Style 63A/66A cartridge seal is specifically designed for ruggedness and durability to withstand higher temperature or dirty services. The Style 63A features a stationary bellows unit for superior performance in applications that require higher shaft runount or large assembly tolerances. The Style 66 is a rotating bellows unit for enhanced solids handling.

Style 63 Features

• Stationary design accommodates higher shaft-to-stuffing box misalignment. The stationary bellows design only flexes once during installation unlike a rotating design which flexes on every revolution. This reduces face movement and increases seal life.
• Bronze steam deflector option available to provide quenching to the inside of the bellows to prevent coke buildup.

Style 66 Features

• Rotating bellows are self-cleaning by design
