We had an unusual service call yesterday (9246 0111) about a submersible bore pump that was producing only about 25% of the water that it normally delivered.
We ruled out all the normal things like a hole in the poly rising main, pump wasn’t running backwards, none of the “normal” causes.??? When we winched the submersible pump to the surface we found the shaft joining the motor to the “wet-end” (pump) seemed OK but on uncoupling the submersible pump we noted inconsistencies. Found the shaft had sheared actually inside the pump leaving the first 4 of 12 impellers still turning. Quite an uncommon fault.
Further detective work found the unusual auto start device had been turning the pump on/off, on/off incessantly contributing to the failure. Replaced the pump and installed it all back down the borehole with the original motor. Tested and all good now!
