Submersible well pump powered by generator


Can I run a 230v submersible well pump 3 wire to a generator and do I need a pressure tank it's used for irrigation purposes

Yes, if the generator is sized to carry the load.

Yes, or your pump will build and lose pressure very quickly and cause your pressure switch to cut on and off rapidly. (click, click,click,click)

Isnt the pressure tank only required for instant access to water and to stop the pump from running every time a draw is required, saving start ups on the motor and increasing its life of the pump?

If he uses a relief valve, shouldn't need a pressure tank but, if he uses a pressure switch the pump would just short cycle. Same as it would if the bladder in the pressure tank for whatever reason, loses air.

If the discharge side can handle the output flow of the pump and can't build pressure, it should be ok.

I'm thinking of a residential irrigation system, where the heads on the open zones may not allow enough flow to keep the pump from building too much pressure.

Hope this makes sense.

I got it, plus i missed the connection of using a pressure switch without a pressure tank...
