LIT Level transmitter with local indicator
Features
- Uses the Plan 61 drain connection.
- Collects the leakage from a single seal in a leakage collection reservoir.
- Is equipped with a level transmitter with a high level alarm.
- This plan is used with a floating or segmented bushing or a similar containment device.
- Identical to Plan 65A except that it uses a normally closed valve in place of the orifice of Plan 65A.
Application
- For single seals with expected condensing leakage.
- Generally for horizontal pumps.
Remarks, checkpoints
- It must be ensured that the valve downstream of the reservoir is always kept closed during operation of the pump.
- Drain connection on the gland must be at the bottom-most position (6 o’clock).
- The valve below the gland (1) should always be kept open during pump operation.
Pump media characteristics
- Condensing, medium temperature fluids
Location, function
- Atmospheric side
- Leakage collection, detection and alarm
