What to do if my BUSCH Water Pump runs very hot?
- D
  Daniel Wilson DDSAug 21, 2025
  If your BUSCH Water Pump runs very hot, several issues could be the cause. Ensure sufficient air ventilation by cleaning fan cowlings, wheels, ventilation grilles, and cooling fins, and ensure adequate ventilation in narrow spaces. Check that the ambient and inlet gas temperatures are within permitted limits. Other potential causes include a partially clogged exhaust filter (replace it), insufficient oil in the reservoir (top up oil), or oil burnt from overheating (flush the pump, replace the exhaust filter, and fill with new oil). Also, verify that the mains frequency or voltage is within the tolerance range and remove any partial clogging from filters, screens, or suction/discharge lines. Finally, ensure that suction/discharge lines aren't too long or have too small a diameter.

How to troubleshoot a BUSCH Water Pump that doesn't start?
- B
  Benjamin YatesAug 23, 2025
  If your BUSCH Water Pump doesn't start, check the following: Ensure the drive motor is supplied with the correct voltage. Verify that the drive motor starter overload protection is appropriately set. Inspect the fuses. Ensure the connection cable is adequately sized to prevent voltage drop. Check for any blockages in the vacuum pump or drive motor. If the motor is blocked, disconnect it from the power supply, remove the fan cover, and try turning the motor by hand. If the pump is blocked, consider contacting Busch service. If the drive motor is defective, consider replacing it through Busch service.

Why does my BUSCH Water Pump expel oil droplets?
- R
  Rachel HarrisonAug 26, 2025
  If your BUSCH Water Pump is expelling oil droplets through the gas discharge, several factors could be responsible. Check that the exhaust filter is properly seated and insert it correctly if necessary. Ensure the o-ring is present and undamaged; replace it if needed. Inspect the exhaust filter for cracks and replace it if any are found. If the exhaust filter is clogged with foreign matter, replace it. Also, inspect the oil return line for clogs or breaks. Clean any clogs or replace broken lines, and top up the oil if necessary.

What causes a BUSCH Water Pump to be blocked?
- M
  Mary BellAug 30, 2025
  A BUSCH Water Pump can be blocked due to several reasons. Solid foreign matter may have entered the pump. Corrosion from remaining condensate can also cause blockage. Additionally, running the pump in the wrong direction can lead to it being blocked. If any of these occur, consider contacting Busch service for repair. Ensure the suction line is equipped with a screen and, if necessary, add a filter.

Why is the oil in my BUSCH Water Pump black?
- A
  Amanda DaySep 1, 2025
  The oil in your BUSCH Water Pump may be black because the oil change intervals are too long or the oil was overheated. To resolve this, flush the vacuum 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.

What causes a BUSCH Water Pump to run very noisily?
- R
  Robert StanleySep 3, 2025
  A BUSCH Water Pump may run very noisily due to defective bearings or stuck vanes. For defective bearings or stuck vanes, consider contacting Busch service for repair. Use only recommended oils and change them more frequently to prevent vanes from sticking.

Why does the gas from my BUSCH Water Pump smell displeasing?
- A
  Amanda MooreSep 6, 2025
  The gas conveyed by the BUSCH Water Pump may smell displeasing due to process components evaporating under vacuum or readily volatile components of the oil, such as additives, especially after an oil change. Check the process and consider using a different type of oil if applicable.

Why is the oil in my BUSCH Water Pump watery and white?
- D
  Daniel ThomasSep 8, 2025
  The oil in your BUSCH Water Pump may be watery and white because the pump aspirated water or significant amounts of humidity. To resolve this, flush the vacuum pump, replace the exhaust filter, and fill with new oil. Modify the operational mode. If your pump has a gas ballast with a sinter metal filter, clean the sinter metal filter using compressed air.

Why does the oil in my BUSCH Water Pump foam?
- B
  Benjamin CarterSep 12, 2025
  The oil in your BUSCH Water Pump may foam due to the mixing of incompatible oils. To resolve this, flush the vacuum pump, replace the exhaust filter, and fill with new oil. Make sure the proper oil is used for topping up.

Why is the oil in my BUSCH Water Pump resinous?
- K
  kristinedyerSep 13, 2025
  The oil in your BUSCH Water Pump may be resinous and/or sticky due to an improper oil type being used, possibly from confusion, or topping up with incompatible oil. To resolve this, flush the vacuum pump, replace the exhaust filter, and fill with new oil. Make sure the proper oil is used for changing and topping up.
