What to do if my BUSCH RA 0205 D Water Pump runs too hot?
- K
  Kirsten GibbsSep 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).

  If the oil in your BUSCH Water Pump is emulsified, it might be because the machine sucked in liquids or significant amounts of vapor, in which case you should contact Busch to flush the machine. Also, clean the filter of the gas ballast valve (GB). Consider modifying the operational mode.

  If your BUSCH Water Pump is fuming or expelling oil droplets, it could be due to: partially clogged exhaust filters (EF) – replace them; an exhaust filter (EF) with o-ring not fitted properly – ensure correct positioning; or a malfunctioning float valve (FV) – contact Busch for repair.

Why BUSCH RA 0205 D has abnormal oil consumption?
- C
  Chad MorganAug 27, 2025
  Abnormal oil consumption in your BUSCH Water Pump can stem from a few issues: oil leaks (contact Busch to replace seals), a malfunctioning float valve (FV) (contact Busch to check and repair the float valve and oil return line), or running the machine at atmospheric pressure for an extended period (ensure the machine operates under vacuum).

What to do if my BUSCH Water Pump does not start?
- G
  Gina PalmerAug 29, 2025
  If your BUSCH Water Pump doesn't start, it could be due to several reasons. First, check if the motor is receiving the correct voltage. If the voltage is correct, the motor might be defective and need replacement. Another possible cause is a defective coupling (CPL), which would also require replacement.

Why BUSCH RA 0205 D Water Pump does not reach the usual pressure?
- B
  bensonmelindaSep 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.

  If your BUSCH Water Pump doesn't start, it could be due to several reasons. First, the motor might not be getting the correct voltage, in this case check the power. Alternatively, the motor itself could be defective and need replacement. Finally, a defective coupling (CPL) could also be the culprit, so replace the coupling (CPL).

Why is my BUSCH RA 0205 D running very noisily?
- M
  Mary EllisSep 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.
