Why BUSCH R5 Oxygen does not reach the usual pressure?
- D
  Dr. Corey Vega MDSep 8, 2025
  If your BUSCH Water Pump isn't reaching the usual pressure on the suction connection, check these potential causes: The oil level might be too low, so top up the oil. The inlet screen (IS) could be partially clogged, so clean the inlet screen (IS). If your pump has an inlet filter cartridge (optional), it might be clogged, so replace the inlet filter cartridge. If none of these resolve the issue, internal parts may be worn or damaged, so repair the machine or contact Busch.

  ycameronSep 7, 2025
  If your BUSCH Water Pump is running too hot, several factors could be the cause. Insufficient cooling may be the issue, so remove any dust and dirt from the machine. Also, the ambient temperature might be too high, so observe the permitted ambient temperature. Low oil level can also cause overheating, so top up the oil. Lastly, partially clogged exhaust filters (EF) could be the problem, in which case replace the exhaust filters (EF).

Why is the oil in my BUSCH R5 Oxygen black?
- S
  Stephanie LewisAug 22, 2025
  If the oil in your BUSCH Water Pump is black, it could be due to oil change intervals being too long, in which case you should contact Busch to flush the machine. Another possibility is a defective inlet filter (optional), which should be replaced. Also, check if the machine is running too hot.

Why does my BUSCH R5 Oxygen emit fumes or oil droplets?
- S
  Sara ArroyoSep 4, 2025
  If your BUSCH Water Pump is emitting fumes or oil droplets through the gas discharge, it could be because the exhaust filters (EF) are partially clogged and need replacement. Also, ensure that the exhaust filter (EF) with o-ring is correctly positioned. If the problem persists, the float valve (FV) might not be working correctly; in this case, check the float valve and the oil return line, and contact Busch for repair if necessary.

Why is my BUSCH R5 Oxygen running very noisily?
- J
  Julia CarterSep 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.

Why is my BUSCH R5 Oxygen consuming oil abnormally?
- S
  Stacey TaylorSep 1, 2025
  Abnormal oil consumption in your BUSCH Water Pump can stem from a few causes. Check for oil leaks and consider replacing the seals. A malfunctioning float valve (FV) can also lead to this issue, so inspect the float valve and the oil return line. Finally, ensure the machine isn't running at atmospheric pressure for extended periods; it should operate under vacuum.

  If your BUSCH Water Pump isn't reaching its usual suction pressure, start by checking the oil level and top it up if it's low. The inlet screen (IS) might be partially clogged, so clean it. If your pump has an optional inlet filter cartridge, it might be clogged and need replacement. If these steps don't resolve the issue, internal parts may be damaged, requiring professional repair by contacting Busch.

  If your BUSCH Water Pump is running too hot, several factors could be responsible. Insufficient cooling may be the issue, so try removing dust from the machine. Also, check if the ambient temperature is too high and ensure it's within the recommended range. Low oil level can also cause overheating, so top up the oil if necessary. Finally, a partially clogged exhaust filter (EF) can cause the pump to overheat, so replace the exhaust filter (EF).
