Unitized Elastomer Bellows Seal Type 502
The Type 502 mechanical seal is one of the best-performing elastomeric bellows seals available. It is suitable for general service and provides excellent performance in a wide range of hot water and mild chemical duties. It is specifically designed for confined spaces and limited glands lengths.
Design Features Type 502
Completely assembled one-piece design for fast installation
• Unitized design incorporates positive retainer/key drive from
bellows
• Non-clogging, single coil spring provides greater
dependability than multiple spring designs. Will not be
affected by build-up of solids
• Full convolution elastomeric bellows seal designed for
confined spaces and limited gland depths. Self-aligning
feature compensates for excessive shaft end play and run-out
