Pump Problem

I have an older dilling harris self-serve system. Over the weekend I had to replace the cat pump and when I put the new one on it ran great. Then as I was leaving the bay tripped out. I tried a few things and got it up and running only to come back the next day and it was out again. This time it said reset contact for the motor starter. When I did that it ran for a bit and tripped out again. Anyone have any idea why this is happening? When I manually push in the motor started it runs fine the whole time. Thanks
 
You are probably pulling too many amps for some reason, which could be as simple as the pressure being too high. I'm sure the electrical gurus can give you some other things to check to help narrow it down.
 
Since this happened right after you changed the pump, I would also suspect the pump. First thing I'd try was to check the pressure, both with the trigger pulled and with it released. If the pressure climbs too high with it released it can overload the motor and cause it to trip. If you didn't do anything to the regulator when you changed the pump, it may have debris in it not letting it work right. You might start there.
 
I think your both right. Should have known better I had the pressure regulator turned up when I was trying to see if I needed to replace the previous pump. Thanks for reminding me I will try that in the morning. I think it will work will let you know if it doesn't.
 
You may also need to set the motor starter amp setting a little higher with the new pump (some have a dial with a 5 amp range). I would use an amp clamp and measure the initial draw and set the it an amp or two above.

Maybe I should ask this question. Why did you have to replace the pump in the first place? Was it too tripping the overload? Or do you feel it's because you tightened down the regulator? I would do what bigleo recommends if after adjusting the regulator and you still trip the overload, which is to test each leg of the electric motor for the amp draw. Maybe the contact, overload, or electric motor has an issue as well.
 
Thanks everyone. Just got home from a long day and it was the pressure regulator. I had adjusted it when I was trying to see if the old pump was done. Any ways turned it down and it fired right up and I ran it for like 30 minutes while I cleaned the bay walls.
