What to do if my BUSCH DOLPHIN LA 0053-1111 A Water Pump does not reach the usual pressure?
- J
  Jessica PhillipsAug 12, 2025
  If your BUSCH Water Pump isn't reaching its usual pressure, several factors could be at play. It could be due to leaks in the vacuum system or suction line, so check hose and pipe connections. The operating liquid might be too warm, in which case you should reduce its temperature. Other potential causes include a leaking mechanical seal (which would need replacing), blocked gas or liquid channels (requiring dismantling and cleaning of the pump), a clogged screen or filter on the suction connection (clean or replace it), blockages in the suction, discharge, or pressure line (remove the clogging), or lines that are too long or have too small a diameter (use a larger diameter). Finally, internal parts may be worn or damaged, requiring repair by Busch service.

Why my BUSCH DOLPHIN LA 0053-1111 A does not start?
- H
  Hannah SloanAug 16, 2025
  If your BUSCH Water Pump isn't starting, there are a few potential reasons. Ensure the drive motor is receiving the correct voltage. Also, check if the drive motor starter overload protection is set too low and compare it with the nameplate data, correcting if necessary. Examine the fuses to see if any have blown. Lastly, verify that the connection cable is adequately sized to prevent voltage drops at the pump.

What to do if my BUSCH DOLPHIN LA 0053-1111 A is blocked?
- R
  Renee ToddAug 20, 2025
  If your BUSCH Water Pump is blocked, it could be due to several reasons. Solid foreign matter might have entered the pump; in this case, you should repair the vacuum pump (Busch service) and ensure the suction line is equipped with a screen and, if necessary, an additional filter. Another cause might be corrosion from remaining condensate, requiring repair by Busch service and a check of the process. Corrosion between the rotor and housing could also be the culprit, which can be eliminated by using anti-rust liquid. Alternatively, ice might have formed in the pump; carefully warm up the pump and defrost the operating liquid. Finally, ensure the pump wasn't run in the wrong direction and refer to the installation instructions for correct direction.

Why my BUSCH DOLPHIN LA 0053-1111 A Water Pump runs very noisily?
- R
  Ronald BeanAug 25, 2025
  If your BUSCH Water Pump is running very noisily, it could be due to several reasons: * Defective bearings, which would require repair by Busch service. * The pump cavitates; try increasing the working pressure or decreasing the temperature of the operating liquid. If it's due to condensable vapors, ensure enough non-condensable gas is conveyed along. Note: continuous operation under cavitation will destroy the pump. * A worn coupling element, which would need to be replaced.

What to do if my BUSCH DOLPHIN LA 0053-1111 A Water Pump starts, but labours or runs noisily or rattles?
- R
  Ronnie LopezAug 27, 2025
  If your BUSCH Water Pump starts but labors, runs noisily, or rattles, consider these potential causes: loose connections in the drive motor terminal box (check, tighten, or replace them), operating liquid level being too high (adjust the regulating valves), operating liquid density or viscosity being too high (use a different liquid or a stronger motor), friction between the rotor and housing (disassemble, clean, and adjust clearances), the pump running in the wrong direction (verify and rectify per the manual), or foreign objects inside the pump (requiring Busch service).

What to do if the drive motor is running, but the BUSCH Water Pump stands still?
- D
  Danny MillerAug 31, 2025
  If the drive motor is running, but the BUSCH Water Pump remains still, the coupling between the motor and pump may be defective, requiring replacement.

Why the gas conveyed by the BUSCH Water Pump smells displeasing?
- A
  Andrew JohnstonSep 4, 2025
  If the gas conveyed by your BUSCH Water Pump has a displeasing smell, it may be due to process components evaporating under vacuum. In this case, check the process, if applicable.

Why my BUSCH DOLPHIN LA 0053-1111 A Water Pump has insufficient air ventilation?
- R
  Richard RomeroSep 7, 2025
  Insufficient air ventilation in your BUSCH Water Pump could stem from a few reasons: the ambient temperature being too high (observe permitted temperatures), the temperature of the inlet gas being too high (observe permitted temperatures), or the mains frequency or voltage being outside the tolerance range (provide a more stable power supply).
