    Why does BUSCH R5 Water Pump have abnormal oil consumption?
    • C
      christopher02Aug 25, 2025
      Abnormal oil consumption in your BUSCH Water Pump can occur due to oil leaks, in which case you should replace the seals. It may also be caused by a float valve that isn't working properly; in this case, check the float valve and the oil return line, repairing it if necessary. Finally, if the machine runs at atmospheric pressure for a long period, make sure that the machine operates under vacuum.

Also, ensure that the ambient temperature is within the permitted range. Check the oil level and top up if it is too low. Finally, the exhaust filters may be partially clogged; in this case, replace them.

    • L
      leonard03Sep 15, 2025
      If your BUSCH Water Pump is fuming or expelling oil droplets, it could be due to partially clogged exhaust filters (replace the exhaust filters), an improperly fitted exhaust filter with o-ring (ensure the correct position of the exhaust filters and the o-rings), a malfunctioning float valve (check the float valve and the oil pipe for clogging and remove any blockages), or, for versions with an oil return valve, running the machine continuously for over 2 hours (regularly shut down the machine for short periods).
