- Scope
- This standard specifies the dimensions of the cascaded balanced mechanical seals, mechanical seals suitable for straight shafts, and sealing cavities for soft packing used in horizontal axial suction centrifugal pumps including GB/T 5662. Although this standard is suitable for general-purpose and heavy-duty process applications, it is not intended for use on processes containing slurries or large quantities of solids. This standard provides two optional cavity series: a) Stuffing box cavity series, suitable for soft packing or mechanical seals used in general-purpose processes, and the limit gauge pressure of the sealing chamber is up to 1.6 Mpa. B) Large cavity series, suitable for mechanical seals for general purposes and heavy working conditions, including integral plug-in mechanical seals, the limit gauge pressure of the sealing chamber is up to 4.0MPa.
