Structure Features:
The HG9 model mechanical seal is a single-face, non-balanced structure with a rubber bellows design. The G60 complies with the DIN24960 standard, the G50 complies with European standards, and the G55 complies with American standards. It features excellent floating adjustment capabilities, allowing for the adjustment of the number of spring coils to meet axial installation requirements. With its simple structure, easy installation, and reliable performance, the HG9 model is recognized by leading international pump manufacturers and is highly favored by users.
The materials for the friction pairs and auxiliary seals should be selected based on actual operating conditions.
Operating Range:

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.
