Plan 53A Flushing System
1. Definition
A pressurized dual mechanical seal flushing system compliant with API 682 standard, designed to supply clean barrier fluid to the seal chamber for reliable sealing protection.

2. Core Features
- Pressurized by inert gas (typically nitrogen) via external regulator.
- Built-in cooling coil for temperature control.
- Equipped with pressure & level monitoring and alarm devices.

3. Working Principle
Pressurized barrier fluid (0.14-0.17MPa higher than process medium) circulates driven by pumping ring, preventing process medium leakage. Leakage can be detected via tank level changes.

4. Applications
- Suitable for toxic, flammable, corrosive or high-temperature media.
- Ideal for explosion-proof areas relying on nitrogen source.
- Not recommended for systems over 2.0MPa (gas dissolution risk).
