What to do if my BUSCH RA 0255 D runs too hot?
- J
  Joseph PeckSep 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 RA 0255 D emulsified?
- N
  Nathaniel FrankAug 25, 2025
  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.

  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 RA 0255 D Water Pump does not start?
- T
  tommyjoyceAug 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 Water Pump does not reach the usual pressure?
- M
  Michael PruittSep 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.
