Structure Features:
The mechanical seal of type HU1 is in accord with ISO3096 DIN24960 & GB6556, according to the working requirements, it could choose an "O" ring or PTEF "V" ring seal of the same specification as an auxiliary seal. Single spring, unbalanced, shifting fork drive, strong compensation ability. It is not related to shift rotation when installing.
Sub-materials of friction and auxiliary materials should be selected according to operation conditions.

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.
