Overview
The HHA4111 is a heavy-duty mechanical seal designed for high-pressure centrifugal pumps. Constructed from tungsten carbide and silicon carbide faces with a hardened alloy casing, it utilizes a dual-carbide configuration to ensure minimal leakage under extreme thermal stress.
Application
- Chemical Processing: Corrosive acid transfer pumps in reactor feed lines.
- Oil & Gas: Crude oil pipelines and high-pressure injection systems.
- Petrochemical: Hydrocarbon separation units and distillation column reboilers.
Precautions
- Operating Limits: Max pressure 25 bar; Temperature range -20°C to +200°C.
- Maintenance: Inspect face wear every 2000 operating hours. Ensure flush flow rates remain above 1 L/min to prevent dry running.
