  If your BUSCH Water Pump starts but runs noisily or rattles, check for loose connections in the drive motor terminal box, ensuring all motor coils are properly connected according to the connection diagram, especially on motors with six coils. Tighten or replace any loose connections. Also, verify the pump is running in the correct direction. If these steps don't resolve the issue, the pump may need repair.

  If your BUSCH Water Pump starts but is running with laboring sounds, unusual noises or rattling, check for loose connections in the drive motor terminal box, ensuring all wires are properly connected according to the connection diagram, especially on motors with six coils; tighten or replace any loose connections. For three-phase motor versions, verify the pump isn't running in the wrong direction. If foreign objects are present or bearings are stuck, it is best to have the vacuum pump repaired by Busch service.

  If the BUSCH Water Pump is running very hot, first ensure sufficient air ventilation by cleaning the fan cowlings, fan wheels, ventilation grilles, and cooling fins to remove any dust or dirt impeding cooling. If the pump is in a narrow space, ensure adequate ventilation. Also, check that the ambient and inlet gas temperatures are within permitted limits.

  If the BUSCH Water Pump is running very noisily, the issue could stem from defective bearings, which would require repair by Busch service. Another potential cause is a worn coupling element, which should be replaced. Low oil level or damage to the synchronizing gear can also cause noise, both of which necessitate repair by Busch service.

  Mitchell ThomasAug 29, 2025
  If the BUSCH Water Pump is blocked, ensure the drive motor is disconnected from the power supply. Remove the fan cover and try turning the drive motor with the vacuum pump by hand. If it remains frozen, remove the drive motor to check it and the vacuum pump separately. If the vacuum pump is blocked, it is best to have the vacuum pump repaired by Busch service.

  Ronnie GallagherAug 30, 2025
  If your BUSCH Water Pump is blocked, it could be due to solid foreign matter entering the pump, requiring repair by Busch service; ensure the suction line has a screen, and consider adding a filter. Corrosion from remaining condensate can also cause blockage, necessitating repair by Busch service; check the process and consult the chapter on conveying condensable vapors. For three-phase motor versions, incorrect running direction can block the pump, requiring repair by Busch service; ensure correct direction upon connection.

  If the BUSCH Water Pump isn't reaching its usual pressure, several factors could be at play. Start by checking the hose or pipe connections for any leaks. If a vacuum relief valve/regulating system is installed, it might be misadjusted or defective, requiring adjustment, repair, or replacement. Also, inspect the screen in the suction connection for clogs and clean it, installing a filter upstream if frequent cleaning is needed. If there is a filter installed on the suction connection, ensure that it is clean. Check for partial clogging in the suction, discharge, or pressure line, and remove any obstructions. If the suction, discharge, or pressure line is too long with a small diameter, consider using a larger diameter. Inspect the valve disk of the inlet non-return valve to make sure it is...
