Overview
The B74-D mechanical seal is a single-spring, cartridge-style unit designed for harsh industrial environments. It features a hardened silicon carbide face mated with a carbon graphite secondary seal, ensuring high abrasion resistance and thermal stability under extreme conditions.
Application
- Chemical Processing: Centrifugal pumps handling corrosive acids and solvents.
- Oil & Gas: Crude oil transfer pumps and refinery feed systems.
- Petrochemical: High-pressure hydrocarbon service in distillation units.
- Water Treatment: Slurry pumps and wastewater circulation systems.
Precautions
- Temperature: Operate within -20°C to +200°C; avoid rapid thermal shock.
- Pressure: Maximum allowable pressure typically 16 bar; verify against specific pump curve.
- Maintenance: Inspect O-rings for swelling during fluid changes; ensure flush line flow remains constant.
