Overview
The HM207BW is a cartridge mechanical seal engineered for high-pressure duties. It features a tungsten carbide mating ring paired with a carbon graphite stationary element, utilizing a double spring actuation system to ensure consistent face contact under thermal expansion.
Application
- Chemical Processing: Centrifugal pumps handling corrosive acids and solvents.
- Petrochemical: Crude oil transfer pumps and refinery feed lines.
- Water Treatment: High-head booster pumps in desalination facilities.
- Power Generation: Boiler feedwater circulation systems.
Precautions
- Temperature: Limit operation between -10°C and +150°C; avoid thermal shock.
- Pressure: Max rated pressure is 25 bar; monitor cavitation risks.
- Maintenance: Flush cooling water continuously; inspect O-rings for chemical degradation every 6 months.
