I have a deep well submersible pump that does not build up any preasure but will kick on for just a minute and then shuts off. It keeps repetting this every minute on so. When it turns on, it sounds like it is runing find, then just before it kicks off it appears to be vibrating. Is the pump shuting down because of an overload?

 

Pump motors have a builtin thermal overload that will automatically shut them down if there's a problem. There are various problems that could make this happen. Call a pump/well person out to check things for you before you pull the pump. If it's an electrical problem the pump and motor may be fine.

Thank you for your reply Ron. I'm trying to avoid a repairman it possible, since I can with help such as yours generally figure out the problem and repair it myself.
I have heard that when you have a problem and do not know whether it is electrical or in the pump that you can hook the pump up directly bypassing all of the controls to see if it runs properly. If so, the problem is in the controls, if not, then the pump needs to be pulled. Have you heard of this?

I might add, that I have bought a new presure switch because I have had problems with this one before. I have not put it in yet. The only other problem I can see would be the control box. The pump is very old. I really feel that it is the problem but am unsure.
Thanks again for your help.

this is possible if it is a two wire pump and not a three wire pump. two wire pumps require a control box and will not start without one. if you are going to do this be very careful as it would be easy to shock yourself.

if you have a multi meter and an amp meter we may be able to walk you though testing. or you could google "franklin electric." look for submserible pump, controls, and the aim manual.

 

Thank you for your help and the reference to Franklin Electric. I will try to use that to determine the problem. I may have to come back for some more help.
I believe that my 3/4 h p submercible is a two wire system. Therefore, as you have said, I will not be able to direct wire it.

Thanks again.

i made a huge typo!!!!!!!!!!!!!!!!!!






a two wire pump does not need a control box and can be direct wired.

a three wire pump does need a contorl box.

 

I have now replaced the presure switch which was fouled and I tried a new control box on the pump. When I tried the pump, it is still coming on but as mentioned before, it vibrates and stays on only a few seconds and then goes off.

May I now conclude that it is either in the wiring running to the pump or the pump, which in either case will require me to pull the pump. Or is there another exclamation.

Bye the way, it is a three wire 3/4 hp pump.

 

I would say that there's a good chance there's a problem in the motor. Inspect the cable as the pump is pulled. If your pump end is still good, you can just replace the motor.

Thanks Ron, and rshackleford,

You both have been tremendous help to me in trying to determine the problem with my pump.

I will now pull the pump. I have never done this before, but with PVC pipe on it, I should be able to handle it by rigging up some jigs to hold as I extract the pump from the well

Thanks again.
