    Why is there no vacuum/pressure generated by my Elmo Rietschle Water Pump?
    • K
      Kimberly GreenAug 7, 2025
      Several factors can cause low or no vacuum/pressure. There could be a leak in the system, so ensure to seal any leaks. The speed reference value might be too low; adjust it within the range of 0-10V. Overheating electronics can also be a culprit, so improve heat dissipation and cooling. An impeller could be dirty or worn, so clean it or consider replacing it. The blower might be too small, consider using a bigger one. Also, if the density of the pumped gas is unequal 1.23 g/m³ then use bigger blower.

    What to do if my Elmo Rietschle 2BH1002-*AB32 motor doesn't start and makes no noise?
    • K
      Kurt DelgadoAug 11, 2025
      If the motor of your Elmo Rietschle Water Pump isn't starting and there's no noise, it could be due to a few reasons. First, check the fuses, terminals, and supply leads to ensure the circuit is complete, as at least two power supply leads might be interrupted. Second, ensure that control signals are applied to inputs A and B. Finally, verify that a speed reference value is set.

    Why is the power consumption too high for my Elmo Rietschle 2BH1002-*AB32 Water Pump?
    • K
      karen94Aug 15, 2025
      High power consumption in your Elmo Rietschle Water Pump can stem from a few causes. A winding short-circuit could be the problem, have the winding checked. Alternatively, the motor might be overloaded; try reducing the operating pressure and clean the filter, silencers, and pipes. Also, check if the impeller is jammed.

    What to do if my Elmo Rietschle Water Pump motor doesn't start but makes a humming noise?
    • R
      Russell NunezAug 20, 2025
      If your Elmo Rietschle Water Pump motor is humming but not starting, the impeller may be jammed. Open the pump lid and remove any dirt or foreign objects. The impeller or motor bearing might also be damaged, consider replacing them. Also, check the connection of the motor phases and hall signals to the drive electronics.

    How to fix abnormal screeching noise in my Elmo Rietschle 2BH1002-*AB32?
    • A
      Amber GrantAug 25, 2025
      An abnormal screeching noise in your Elmo Rietschle Water Pump could be due to a flow rate that is too high; increase the pipe cross-section and clean the pipe. Another possible cause is a damaged ball bearing; in this case, replace the complete casing, which includes the casing, stator, and two ball bearings.

    What causes current feed to the mains in my Elmo Rietschle 2BH1002-*AB32?
    • A
      aaron23Aug 29, 2025
      Current feed to the mains in your Elmo Rietschle Water Pump is caused by switching off or rapidly reducing the speed of the blower. To solve this, insert a diode (Schottky diode, size 6A respectively 10A) in the 24V respectively 48V supply lead (+V).

    What causes an impeller leak in my Elmo Rietschle Water Pump?
    • M
      Morgan MartinSep 2, 2025
      An impeller leak in your Elmo Rietschle Water Pump can occur if the relative pressure between the blower and its surroundings is too high. Ensure that the permissible differential pressure between the pump interior and the surroundings is not exceeded.
