6. Vedligeholdelse

Regular maintenance is crucial for the longevity and optimal performance of your EBARA pump. Always disconnect power before beginning any maintenance procedures.

6.1 Rutinemæssig inspektion

• Check for leaks around the shaft seal and piping connections.
• Listen for unusual noises or vibrations during operation.
• Monitor motor temperature.

6.2 Disassembly and Inspection (without removing piping)

A key feature of the LPD pump is the ability to disassemble and inspect internal components without detaching the pump from the main piping. Refer to the detailed exploded view diagram (not provided in this document, refer to official EBARA service manual) for specific steps. This typically involves:

1. Shutting down the pump and isolating it from the power supply.
2. Draining the pump casing.
3. Removing the motor and impeller assembly from the casing while the casing remains inline.
4. Inspecting the impeller, mechanical seal, and bearings for wear or damage.
5. Replacing worn parts as necessary.
6. Reassembling the pump, ensuring all seals are correctly seated.

6.3 Mechanical Seal Replacement

The pump uses a mechanical seal. If leaks persist from the shaft seal, the mechanical seal may need replacement. This is a precision component and should be handled with care. Consult a qualified technician for replacement if you are unfamiliar with the procedure.
