Why does my BUSCH R 5 RA/RC 0010 C fumes or expels oil droplets through the gas discharge?
- K
  Kimberly RoyAug 29, 2025
  If your BUSCH Water Pump is fuming or expelling oil droplets, check the exhaust filter's position and correct it if necessary. Ensure the o-ring is present and undamaged; add or replace it if needed. If the exhaust filter is cracked or clogged, replace it. For versions with an oil return valve (RA ... C, 0.5 mbar), shut down the pump regularly for short periods if it runs for more than 2 hours to prevent oil accumulation in the upper chamber of the oil separator. Also, check that the oil return valve functions properly, allowing oil to flow from the upper to the bottom chamber when the pump is shut down.

  Michael SalasAug 31, 2025
  The oil in your BUSCH Water Pump may be black due to extended oil change intervals or overheating. To resolve this, flush the pump, replace the exhaust filter, and fill with new oil. If the oil life is too short, consider using oil with better heat resistance or retrofitting cooling.

Why is the oil watery and colored white in my BUSCH R 5 RA/RC 0010 C?
- W
  Walter WashingtonSep 3, 2025
  The oil in your BUSCH Water Pump might be watery and white if the pump has aspirated water or significant amounts of humidity. If your version has a gas ballast, the filter might be clogged. To address this, flush the pump, replace the exhaust filter, and fill with new oil. Modify the operational mode to prevent further water aspiration. If equipped with a gas ballast with a paper filter, replace the filter.

Why is the oil resinous and/or sticky in my BUSCH Water Pump?
- K
  Kyle CoxSep 9, 2025
  The oil in your BUSCH Water Pump is resinous and/or sticky due to using an improper oil type or topping up with incompatible oil. To resolve this, flush the pump, replace the exhaust filter, and fill with new oil, ensuring you use the correct oil for both changing and topping up.

What to do if the drive motor is running, but the BUSCH R 5 RA/RC 0010 C stands still?

  Carlos LiSep 12, 2025
  If the drive motor runs but the BUSCH Water Pump remains still, the coupling between the motor and the pump is likely defective. Replace the coupling element to resolve this issue.
