Structure Features :
Single-end balanced mechanical seal, convenient and reliable installation, large spring (multi-spring) externally does not contact the medium, and adopts an open sealed cavity. The external flushing water (API682 Plan62 flushing scheme) has a pressure of ≤0.05MPa, and the rapid cooling liquid is kept unobstructed and uninterrupted
Operating Range:
Mediums: suitable for conveying medium with high suspended solid particles in the liquid (such as ore slag, coal slime, sediment) and other solid content ≤30% (wt)
Pressure: ≤1.6Mpa

We maintain close communication with clients to guarantee all finished products satisfy operational and environmental requirements.
A: First, identify the optimal configuration (single or double seal) according to the process fluid. Then verify operating parameters — pressure, temperature and shaft speed — to select the appropriate seal type and materials. Lastly, confirm available installation dimensions, and opt for either a component or cartridge seal subject to customer requirements and relevant standards. Seal selection is normally carried out by qualified technicians.
A: For mechanical seals that have been stored for a long period: we can grind the rotating and stationary rings, replace secondary sealing O-rings, conduct air tightness testing and issue the pressure test report.
We can provide on-site installation guidance service. For failed mechanical seals, we are able to deliver failure analysis reports.
A: Yes, repairs are available. Depending on the damage condition of the mechanical seal, we classify the overhaul into Level 1, Level 2 and Level 3 repair.
