  Daniel HardyJul 28, 2025
  An insufficient flow rate in your DAB Water Pump could stem from several causes. Begin by checking the suction filter for partial clogging, especially in PULSAR pumps, and remove any obstructions. Make sure that impellers or the delivery pipe aren't partly blocked or fouled with scale; clear any obstructions. Check the impellers for wear and replace them if necessary. Examine the check valve (if fitted) for partial clogging and clean it thoroughly. Invert two wires in the power cable.

  If your DAB Water Pump isn't delivering water, several factors could be at play. Start by checking for blockages in the suction filter or pipes and remove any obstructions. Inspect the impellers for wear or blockages, replacing or clearing them as needed. Ensure the check valve (if installed) isn't stuck closed; if it is, verify its operation and replace if necessary. Confirm that the fluid level is adequate, ensuring the water level surpasses the filter level upon startup, adjust the float switch cable according to the manual. Finally, prime the pump.

  If the overload protection device is stopping your DAB Water Pump, it might be due to several reasons. Ensure the fluid being pumped isn't too dense, as this can cause the motor to overheat. Also, verify that the water temperature is within the specified range. Check the pump for blockages caused by impurities and clean it thoroughly. Finally, inspect the pump for mechanical issues such as rubbing between moving and fixed parts, and check the wear of the bearings.
