    Why is the oil in my BUSCH R5 RD 0240 A Water Pump black?
    • G
      George McphersonAug 9, 2025
      The oil in your BUSCH Water Pump might be black because: * Oil change intervals are too long. In this case, flush the machine (contact Busch). * The inlet filter (optional) is defective and needs to be replaced. * The machine runs too hot. See problem "The machine runs too hot".

      If the oil in your BUSCH Water Pump is emulsified, it's likely because the machine sucked in liquids or significant amounts of vapor. You should flush the machine (contact Busch) and clean the filter of the gas ballast valve (GB). Modify the operational mode (see Conveying Condensable Vapors [? 22]).

    Why is my BUSCH Water Pump running very noisily?
    • M
      Mr. Howard Bell IIAug 28, 2025
      If your BUSCH Water Pump is running very noisily, it could be due to: * A worn coupling (CPL), which would need to be replaced. * Stuck vanes or defective bearings. In both of these cases, repair of the machine is needed (contact Busch).

    What to do if my BUSCH Water Pump fumes or expels oil droplets?
    • A
      Alan HowardSep 2, 2025
      If your BUSCH Water Pump is fuming or expelling oil droplets through the gas discharge, consider these possibilities: * The exhaust filters (EF) might be partially clogged, in which case you should replace them. * An exhaust filter (EF) with o-ring may not be fitted properly. Ensure the correct position of the exhaust filters (EF) and the o-rings. * The float valve (FV) might not be working correctly. Check the float valve. Repair of the machine is needed (contact Busch).
