Structure Features:
The HU21 model mechanical seal complies with DIN24960 standards and features a single spring, single-face, rubber bellows, and a non-balanced structure. The rotating ring is driven by the interference fit, not the bellows, providing good floatability, and torque is transmitted via a drive fork.
Operating Range:
Mediums: water, oil, and other mildly corrosive media containing particles
Pressure: ≤1.0MPa
Temperature: -20°C to 120°C
Linear Speed: ≤ 15 m/s

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.
