Plan 65A (Leakage Detection Pot)
Why do we use it?
- When we want to monitor the rate of leakage across a mechanical seal and alarm when the rate is high
- When the leakage from the mechanical seal must be directed to a safe drain
Advantages:
Provides an alarmed indication of excessive seal leakage that can shutdown equipment if necessary.
General:
The system includes a loop to by-pass the orifice to prevent high pressure on the atmospheric side of the seal. The gland throttle bushing design should consider the fluid’s properties.
