Pompetravaini Centrifugal Pump TCD

Ensure the engine is off and cooled down

Gather necessary tools and materials (oil, oil-cruet, etc.)

Remove vent plug of the bearing frame

Dispose of the exhausted oil following current regulations

Pour oil into the bearing frame through the hole of plug till oil is visible in the oil-filler elbow

Adjustment of Packing Seals Without External Flushing

Loosen the stuffing box nuts to allow a strong drip to escape

Verify the extent of the leak (drops per minute)

Tighten the stuffing box nuts progressively until the leak is reduced to a controlled drip

Wait a few minutes and verify the stabilized leak rate (drops per minute)

Is the leak rate within the acceptable range (60-200 drops per minute)?

Measure the temperature of the liquid that comes out

Is the temperature at least 10°C lower than the boiling temperature and below 90°C?

Is the dripping insufficient (high temperature)?

!CAUTION: Possible contact with hazardous media and hazardous substances, cold or warm. Operate only provided with apposite protective devices.

Wear appropriate protective devices

Ensure maintenance is carried out when the pump is at a standstill.

Disconnect the power supply and any other connections.

Ensure power supply is restored only by the operator performing maintenance.

Ensure presence of at least two operators and inform the foreman of maintenance in progress.

!DANGER: Danger due to fluids in pressure. Carry out sealing tests provided with apposite protective devices.

Ensure all protective devices are in place

Verify that the installation is complete
