  If the HERBORNER pumpentechnik Water Pump delivery is too low, it may be due to several reasons. The density of the pumped medium might be too high, in which case you should dilute the medium or alter the process. Alternatively, the pump might be working against high pressure, so you should measure the pressure and check the pump layout. Ensure that the gate valves are fully open and that the pipeline and pump are not obstructed. Also, verify the pump is not running on two phases by checking the connections or exchanging the defective locking device. Finally, inspect the impeller for wear or looseness and replace it if necessary.

  If your HERBORNER pumpentechnik Water Pump runs but immediately switches off, the motor circuit breaker may have been triggered due to insufficient cooling, so provide adequate motor cooling. The issue could also stem from an incorrect direction of rotation, so check the rotation. High power input can also cause this, so ensure the pump moves freely. Other potential causes include high density of the pumped medium (dilute it or alter the process), the pump not operating in the specified range (check operating conditions), an obstructed pump triggering the motor protection relay (check pump movement), frequent pump switches (observe operating mode), or incorrect motor connection (connect the motor to the correct operating voltage).

  Jessica StricklandAug 13, 2025
  If your HERBORNER pumpentechnik Water Pump's electric motor is overly warm, it could be due to several factors. Check for an incorrect direction of rotation and correct it if necessary. Ensure the pump operates within its specified range. If the pumped medium is too dense, dilute it. Clear any obstructions in the supply pipe or impeller. If the motor isn't powerful enough, replace it with a more powerful model. Verify the motor is correctly connected to the appropriate voltage. Ensure the coolant temperature is not above 40 °C by checking ventilation paths. Lastly, observe the operating mode to see if the pump switches too often.

Why does my HERBORNER pumpentechnik UNIBAD-X Water Pump vibrate or make noise?
- J
  Janet HarrisAug 17, 2025
  If the HERBORNER pumpentechnik Water Pump vibrates or makes noise, it could be due to a high concentration of air or gas in the pumped medium, requiring further investigation. An incorrect direction of rotation could also be the cause, so check the rotation and correct it if necessary. Inspect the impeller for looseness or wear and replace if needed. Ensure the pump is operating within its specified range by checking the operating conditions.

  Lisa StewartAug 22, 2025
  If your HERBORNER pumpentechnik Water Pump isn't pumping and there's a danger of running dry, first ensure the pump and pipeline are completely filled and de-aerated. Check for any obstructions in the supply pipe or impeller and clean them, removing any sediment deposits. Verify that the motor is running by checking the electrical installation. Make sure the gate valves are open. Also, check the plant for any impurities and/or the layout of the pump, as the head might be too high.

Why is the bearing of my HERBORNER pumpentechnik UNIBAD-X Water Pump becoming hot?
- V
  Victoria RodriguezAug 27, 2025
  If the bearing of your HERBORNER pumpentechnik Water Pump becomes hot, it could be due to several reasons. It might be running without enough lubrication, so top up the grease and replace the bearing if necessary. Alternatively, there might be too much grease, in which case you should remove the surplus until the balls are just covered. Ensure the pump is not installed under tension by laying connecting pipes in an unstressed manner. Finally, the anti-friction bearing itself might be defective and need replacement.
