The mechanical seal for the 59U type pump utilizes a wedge-shaped ring made of polytetrafluoroethylene (PTFE) as an secondary sealing ring for both the rotating and stationary rings.

The 58U mechanical seal utilizes rubber O-rings as the rotating and stationary rings' auxiliary sealing rings.

It complies with ISO3069, DIN24960, and GB/T 6556 standards. It also conforms to the American Petroleum Institute standard API 610.

It is a single-end, multi-spring unbalanced structure with small axial dimensions and a compact design, widely applicable to the sealing of rotating shafts in pumps, reactors, compressors, and similar equipment.
