    Why is my Texmo Industries Taro Pumps NMH 7040 Water Pump consuming excess current?
    • L
      Lydia AndersonAug 11, 2025
      Excessive current consumption in your Texmo Industries Water Pump can stem from several issues. Check for single phasing by examining the line fuses and the availability of a three-phase supply. Low voltage can also cause this, so verify the voltage. Other potential causes include a defective rotor (replace the rotor), the rotor rubbing against the stator ID due to bending (check and replace the rotor), or a low system head leading to higher discharge (throttle the discharge).

    What to do if Texmo Industries Water Pump discharge is low?

      Jessica NguyenAug 17, 2025
      If your Texmo Industries Water Pump has a low discharge, several factors could be responsible. Ensure you are operating within the recommended voltage range. For three-phase pumps, check if the rotation is incorrect and interchange any two phases. Verify that the static suction lift is within the recommended limits. Also, confirm that the total head isn't higher than the specified head. Inspect the piping system for leaks and fix any faults. Make sure you're using the recommended pipe size. Clean the discharge pipe if it's internally coated with deposits. Check the impeller and casing for foreign bodies and remove them. Inspect the valve in the discharge pipe for blockages and clean or replace if necessary. Finally, examine the impeller for wear and replace if needed.

    How to troubleshoot a rough and noisy Texmo Industries Taro Pumps NMH 7040 Water Pump?
    • L

      A Texmo Industries Water Pump that runs rough and noisy may have several underlying issues. Start by checking the bearings for wear and replace them if necessary. High suction lift can cause cavitation, so reduce the static suction lift. Ensure the pump is properly grouted. Inspect the rotor shaft for bending, which could cause rubbing against the stator bore, and replace the shaft if needed. Also, check the impeller for excessive wear and replace it if necessary.

    Why is the total head developed by my Texmo Industries Taro Pumps NMH 7040 Water Pump too low?
    • T
      thomasstevensAug 29, 2025
      If the total head developed by your Texmo Industries Water Pump is too low, it could be due to an increased clearance between the pump impeller and wear plate; in this case, you should check and replace worn-out parts. Another potential cause is abrasive or corrosive wear of the pump hydraulics, which would also necessitate changing the worn-out pump parts.

    How to fix a Texmo Industries Taro Pumps NMH 7040 Water Pump that does not discharge water?
    • A
      Amber JohnsonNov 4, 2025
      If your Texmo Industries Water Pump isn't discharging water, several factors could be the cause. First, ensure the pump is primed. Check for a faulty foot valve or blocked strainer and replace or clean them as needed. Inspect the suction side for air leakages and correct them. Make sure the suction lift isn't too high and reduce it if it is. Ensure the suction pipe free end or foot valve is sufficiently submerged, ideally with the foot valve at least 1 meter below the water's surface. Also, check if the NRV is jammed and replace it if necessary. Other potential issues include a burnt motor coil (rewind the motor), a weak capacitor in single-phase pumps (replace the capacitor), low-voltage operation (operate within the recommended voltage range), a tripped motor starter overload (reset the ...
