What to do if my HERBORNER pumpentechnik Water Pump doesn't pump and is in danger of running dry?
- J
  Jennifer TaylorAug 3, 2025
  If your HERBORNER pumpentechnik Water Pump isn't pumping and there's a risk of it running dry, it could be due to a few reasons. First, the pump or pipeline might not be completely filled, so you should de-aerate and fill both. Another possibility is that the supply pipe or impeller is blocked; in this case, clean the supply and remove any sediment deposits from the pump or pipeline. Also, check the electrical installation to ensure the motor is running and make sure that the gate valves are open.

Why does my HERBORNER pumpentechnik Water Pump vibrate or make noise?
- B
  barrettamyAug 22, 2025
  If your HERBORNER pumpentechnik Water Pump is vibrating or making noise, it could be due to a high concentration of air or gas in the pumped medium. Another potential cause is an incorrect pump direction of rotation; in this case, check the direction and swap two phases to the motor if necessary. Additionally, the impeller might be loose or worn, so inspect it and replace it if needed.

Why is the bearing of my HERBORNER pumpentechnik Water Pump getting hot?
- J
  Jeremy BeasleyAug 28, 2025
  If the bearing of your HERBORNER pumpentechnik Water Pump is getting hot, it could be due to several reasons. The bearing might be running without enough lubrication, so top up the grease, replacing the bearing if necessary. Alternatively, there might be too much grease in the bearing, so remove the surplus until the ball bearings are just covered. Another cause could be that the pump is installed under tension, so ensure the connecting pipes are laid stress-free. Finally, the anti-friction bearing might be defective, in which case it should be replaced.

Why is my HERBORNER pumpentechnik Water Pump electric motor getting excessively hot?
- J
  Julie FosterNov 7, 2025
  There are several reasons why the electric motor of your HERBORNER pumpentechnik Water Pump might be getting excessively hot. It could be due to an incorrect pump direction of rotation, so check the rotation and swap two phases to the motor if needed. The pump might not be operating within the specified range, so check the operating conditions. If the pumped medium is too dense, dilute it or alter the process. Obstructions in the supply pipe or impeller can also cause overheating, so clean the supply and remove sediment. Other potential causes include a motor that isn't powerful enough (replace it with a more powerful one), incorrect motor connections (connect it to the correct operating voltage), coolant temperature exceeding 40 °C (check ventilation paths), or the pump switching too ofte...

What to do if the delivery of my HERBORNER pumpentechnik Water Pump is too low?

  Karen SanchezNov 11, 2025
  If the delivery of your HERBORNER pumpentechnik Water Pump is too low, several factors could be the cause. The head might be too high, or the pump might not be correctly placed in the suspension, or the pumped medium might be too dense. Check the plant for any impurities and the pump's selection and placement. Dilute the pumped medium or change the process. Also, check the pump's direction of rotation and swap two phases to the motor if necessary. Inspect the impeller for looseness or wear and replace it if needed. Measure the pressure if the pump is pumping against excessive pressure, and adjust the pipe configuration or pump selection accordingly. Ensure the gate valves are fully open, and check the pipeline and pump for blockages, cleaning as necessary. Finally, check for a defective fu...

What to do if my HERBORNER pumpentechnik Water Pump starts up but switches off immediately?
- M
  meyersdeborahNov 16, 2025
  If your HERBORNER pumpentechnik Water Pump starts up but immediately switches off, it could be due to several reasons. The motor circuit breaker may have tripped due to insufficient motor cooling, so ensure adequate cooling is provided. An incorrect pump direction of rotation could also cause this, so check the rotation. High power input can be a factor, so verify that the pump can move freely. If the pumped medium is too dense, dilute it or change the process. Also, check that the pump operates in the specified range. A blocked pump triggering the motor protection relay can cause this issue, so ensure the pump can move freely. Check the level switch if the float switch is not adjusted correctly. Observe the operating mode; if the seal monitoring was activated, chick oil in the rear wall. ...
