A 3/4 HP 10 GPM shallow well pump for irrigation ran dry for a couple hours due to a technical failure where a feeding valve mounted at the pump inlet blew out of its hole. All the water being pumped escaped from the hole and allowed the pump to lose prime and run dry. When I got to it everything was really hot.
After fixing the PVC and re-priming I tested the GPM and determined I have 50% less (5 GPM). I need the full 10 GPM for my system to work properly.
What exactly failed inside my pump from running dry and can I fix it? I have had this pump apart in the past for another reason so I am comfortable with replacing parts inside.
I'd rather buy overhaul kit parts for $30 than a new pump for $200, but if you think it's too far gone and might not work fully to 10 GPM after the repairs I'll just get the new pump.
