    What to do if my BUSCH R 5 runs very noisily?
    • J
      James MurraySep 23, 2025
      If your BUSCH Water Pump is running very noisily, it could be due to a few reasons. The coupling (CPL) might be worn and need replacement. Alternatively, the vanes could be stuck, or the bearings could be defective. For stuck vanes or defective bearings, contact Busch for machine repair.

    Why does my BUSCH Water Pump have abnormal oil consumption?
    • J
      Jeffrey DunnAug 25, 2025
      Abnormal oil consumption in your BUSCH Water Pump can stem from a few issues. Oil leaks could be the problem, in which case the seals need replacement (contact Busch). Another potential cause is a malfunctioning float valve (FV), requiring a check of the valve and oil return line, and repair if necessary (contact Busch). Lastly, operating the machine at atmospheric pressure for extended periods can lead to this issue, so ensure the machine operates under vacuum.

    Why is the oil in my BUSCH R 5 Water Pump emulsified?
    • J
      Jessica GilbertAug 26, 2025
      If the oil in your BUSCH Water Pump is emulsified, it could be because the machine sucked in liquids or significant amounts of vapor, in which case you should flush the machine (contact Busch). Another cause may be that you need to clean the filter of the gas ballast valve (GB). You might also need to modify the operational mode (see Conveying Condensable Vapours).

      If your BUSCH Water Pump doesn't start, there could be several reasons. First, check the power supply to ensure the motor is getting power. If the power supply is fine, the motor itself might be defective and require replacement. Another possibility is a defective coupling (CPL), which would also need to be replaced.
