Applications:The Type 502 is a 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.
1.Industries include chemical processing, food processing, gas compression, marine, nuclear service, offshore, oil & refinery, paint & ink, petrochemical processing, pharmaceutical, pipeline, power generation, pulp and paper, wastewater, water desalination, water systems.
2.All types of rotary equipment, pumps, marine, mixers, agitators, blowers, fans and compressors in a variety of service applications.
3.Supplied completely
Design Features/Benefits1.Fast Installation Completely assembled one-piece design for fast installation.
2.Unitised Design Unitised design incorporates positive retainer/key drive from bellows.
3.Non-Clogging, Single Coil Spring Provides greater dependability than multiple spring designs. Will not be affected by build-up of solids.
4.Compact Design 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.
