    What causes a BUSCH R5 ATEX to fume or expel oil?
    • M
      Melvin HigginsSep 23, 2025
      If your BUSCH Water Pump is fuming or expelling oil droplets through the gas discharge, the exhaust filters (EF) might be partially clogged and need replacement. Ensure that the exhaust filter (EF) with o-ring is fitted correctly. Another possible cause is a malfunctioning float valve (FV); inspect it and the oil pipe for any blockages, and clear them if necessary.

    Why is the oil in my BUSCH R5 ATEX emulsified?
    • P
      Philip JenningsAug 25, 2025
      If the oil in your BUSCH Water Pump is emulsified, it might be because the machine sucked in liquids or significant amounts of vapor, in which case you should contact Busch to flush the machine. Also, clean the filter of the gas ballast valve (GB). Consider modifying the operational mode.

      If your BUSCH Water Pump is fuming or expelling oil droplets, it could be due to: partially clogged exhaust filters (EF) – replace them; an exhaust filter (EF) with o-ring not fitted properly – ensure correct positioning; or a malfunctioning float valve (FV) – contact Busch for repair.

      William PayneAug 27, 2025
      Abnormal oil consumption in your BUSCH Water Pump can stem from a few issues: oil leaks (contact Busch to replace seals), a malfunctioning float valve (FV) (contact Busch to check and repair the float valve and oil return line), or running the machine at atmospheric pressure for an extended period (ensure the machine operates under vacuum).

    What to do if BUSCH R5 ATEX doesn't reach usual pressure?
    • J
      John RiversSep 16, 2025
      If your BUSCH Water Pump isn't reaching the usual pressure, consider these potential causes: * The oil level might be too low (top up oil). * The inlet screen (IS) could be partially clogged (clean the inlet). * The inlet filter cartridge (optional) might be partially clogged (replace the inlet cartridge). * Internal parts may be damaged; in this case, contact Busch for repair.

    Why BUSCH R5 ATEX does not start?
    • R
      Ralph RobertsSep 13, 2025
      Your BUSCH Water Pump might not start due to several reasons: the motor may not be receiving the correct voltage (check the voltage), the motor itself could be defective (replace the motor), or the coupling (CPL) might be defective (replace the coupling).

    What to do if BUSCH R5 ATEX Water Pump runs too hot?
    • M
      Miguel HartmanSep 15, 2025
      If your BUSCH Water Pump is running too hot, it could be due to several reasons: insufficient cooling (remove dust and dirt from the machine), the ambient temperature might be too high (observe the permitted ambient temperature), the oil level might be too low (top up oil), or the exhaust filters (EF) could be partially clogged (replace the exhaust filters).

    Why my BUSCH Water Pump does not start?
    • W
      westanthonySep 5, 2025
      If your BUSCH Water Pump doesn't start, it could be due to several reasons. First, the motor might not be getting the correct voltage, in this case check the power. Alternatively, the motor itself could be defective and need replacement. Finally, a defective coupling (CPL) could also be the culprit, so replace the coupling (CPL).

    Why is my BUSCH R5 ATEX Water Pump running very noisily?
    • K
      Kelly KingSep 3, 2025
      If your BUSCH Water Pump is operating with excessive noise, it could be due to a worn coupling (CPL), which would need replacement. Alternatively, stuck vanes or defective bearings might be the cause, in which case you should contact Busch for machine repair.
