Overview
The HMB9J is a heavy-duty mechanical seal designed for rotary shaft isolation. It features a tungsten carbide primary face paired with a graphite secondary ring, utilizing a viton elastomer O-ring system. The unit employs a balanced design to minimize heat generation under high-load conditions.
Application
- Chemical Processing: Centrifugal pumps handling corrosive acids and solvents.
- Oil & Gas: Reciprocating compressors and crude oil transfer pumps.
- Water Treatment: High-pressure booster pumps in desalination plants.
Precautions
- Operating Limits: Max pressure 16 bar; Temperature range -20°C to +150°C.
- Maintenance: Inspect face wear every 2,000 hours; ensure flush water flow remains above 0.5 L/min.
- Installation: Verify shaft runout does not exceed 0.05mm to prevent premature failure.
