Maintenance Points of Centrifugal Pump Casing

1. Regular inspection

- Appearance inspection: Regularly inspect the appearance of the pump casing to look for cracks, deformation, corrosion, wear or other physical damage.

- Internal inspection: If possible, regularly disassemble the pump casing to check whether there is abnormal wear, sediment or other problems that affect the flow inside.

2. Seal status inspection

- Seal ring and gasket: Check the integrity of the seal ring and gasket on the pump casing to ensure that there is no wear, aging or leakage. Replace if necessary.

- Connection flange: Check the sealing status of the flange connection to ensure proper tightening to avoid leakage.

3. Cleaning

- Regular cleaning: Clean the pump casing and its surroundings regularly to remove dirt, grease or other debris, ensure the cleanliness of the pump surroundings, and reduce corrosion and damage to the pump casing.

- Inner cavity cleaning: If there is sediment in the pump, it can be cleaned with an appropriate cleaning agent. Be careful not to damage the smooth surface inside the pump casing when cleaning.

4. Corrosion protection

- Coating inspection: If there is an anti-corrosion coating on the surface of the pump casing, check the coating status regularly. If peeling or wear is found, re-apply.

- Material selection: For fluids with more complex chemical properties, ensure that the pump casing material is resistant to corrosion.
