Features
- Utilizes an orifice plug to limit the amount of leakage leaving the seal gland.
- Normal leakage continues to flow freely to the drain port.
- Excessive leakage causes a pressure build-up upstream of the orifice plug which subsequently triggers a pressure alarm by the pressure transmitter.
Application
- Commonly used on horizontal pipeline pumps.
Remarks, checkpoints
- It must be ensured that the leakage from the drain port is collected and piped to a leakage recovery system.
- Drain connection on the gland must be at the bottom-most position (6 o’clock).
- Media properties to be checked for possible blockage of the orifice plug due to congealing.
Pump media characteristics
- Low to medium temperature liquids
Location, function
- Atmospheric side
- Leakage limiting detection and alarm
Configurations
