Overview
A HMR mechanical seal is a high-performance rotary sealing unit designed for severe service conditions. It typically utilizes ceramic and silicon carbide faces paired with elastomer or metal bellows. The design ensures zero leakage under extreme thermal shock, featuring robust hardened alloy components to resist abrasion.
Application
- Oil & Gas: Centrifugal pumps in refineries and subsea manifolds.
- Chemical Processing: Agitators and reactors handling corrosive acids.
- Petrochemical: High-pressure feed pumps and compressor units.
- Power Generation: Boiler feedwater systems and turbine seals.
Precautions
- Temperature: Operate strictly within -40°C to +250°C limits.
- Pressure: Max dynamic pressure must not exceed 15 bar.
- Maintenance: Inspect O-rings for swelling monthly; flush cooling lines weekly.
