Structure Features :
The mechanical seal adopts a single-end face, multiple springs (or wave springs), and an unbalanced cartridge structure. The end face load is uniform, the rotation direction is not limited, and the installation is convenient and reliable.
The flushing scheme can use PLAN11 + 61 (62).
Operating Range:
Mediums: oil, water, acid, alkali, salt and other corrosive medium.
Pressure: ≤1.6Mpa
Temperature: -40℃~220℃
Linear Speed: ≤20m/s

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.
