Franklin pump cutting out


I'm trying to get a pump working on an old borehole. I've checked the wiring to the control box and pump and made sure its correct. However on turning the pump on, it runs for a minute and a half then the control box clicks out. When you turn it off for a few minutes and start again it does the same thing. My voltage is correct. control box wired in correctly. Can anyone suggest why its doing this?

Thanks craig

Does the pump work normally? (Observe the stream of water as pumped onto the ground.)

Is the pump too far below the surface for its strength rating?

Is the outlet pipe or hose too fat (more weight of water to pump up) or too skinny (more friction and resistance)?

What your describing is pretty classic symptoms of an overload trip. I'd say the overload is in the controller, but it could be in the motor also. If you only are running it for a short period, I'd say go to the next larger control box and try that. Otherwise, you'll need to find out why it's pulling enough amps to cause the overloads to trip. To clarify - it's not pulling super high amperage - just enough to cause it to trip the overload after a 1.5 minute period.

Also, this whole theory is kaput if you can shut the power and immediately turn it on and start the pump again? If so, I'd look for a faulty pump protection circuit in the system.

Do you have a way to measure current? Like said above, it may be tripping on overload.

I will test the pump on the ground. The pump is a .75kw and I think is quite tired. Its has a 50mm pipe and pump has to pump 65m up to ground level. Sorry it sometimes takes a while to reply with all that goes on in my conservancy.

Could you explain more in depth in how exactly I would measure this. Sorry more mechanically minded than electrical.

65 meter = 213 feet

And if I did the converson right with KW that is pretty much 3/4 hp motor
