Double seal with multi spring structure, the spring is placed in the atmosphereand does not come into contact with the medium or buffer solution, greatly reducing the risk of spring failure and improving the sealing life.
Larger buffer chamber flushing space, bidirectional flow design, more significant cooling effect.
Suitable for Plan 52.53A.54.55.
