Description
Leakage from seal faces is directed to a liquid collection system. A vessel with a high level alarm is provided for detection of cumulative leakage.
Features
- Normally used with single seals where the leakage is expected to be mostly liquid.
- Piping is connected to the drain connection of the gland plate.
- Leakage is collected in the vessel until the high level alarm is reached. Excessive fill rate indicates seal failure.
- Vessel overflow prevents vessel pressurisation in event of seal failure.
Use
- In services where seal leakage is condensing.
- Used for single seals.
Caution
- Vent connection should always be plugged.
- Overflow line should bypass system drain valve.
- The valve between seal and system must remain open during pump operation.
- Reservoir must be located below seal gland.
