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.
