How to Size a Generator for Your Well Pump

[@edbouhl3100]

Just to repeat an answer at the end of the video that I came looking for, if you’re deciding on a pump that may run on a portable generator, a 3-wire pump (4 including ground) with an external control box is better than a 2-wire pump. The 2-wire pump will require 50% more power on startup which may require a larger generator than you’d otherwise need.

Woot. New video!

Please could you do a video on NPSH?

What size generator would I need to run a 1/2 hp 2-wire well pump. Will a Predator 4375 do the job? If it will then I have another issue.

I have 2hp submersible Franklin motor pump, what size or hp of generator I can used?

[@mahimmallick8982]

Can i run 1.5 hp pump in max output 3000w generator?

[@geohn77]

Do you have any examples of internally regulated generators that can be purchased?

[@lucianorodriguez1747]

I have the same question. There is no info online.

This doesn't really answer your question but you don't want a brushless generator they have the noisiest output. The regulating is done through a capacitor and the windings of the generator and it induces a DC voltage in the rotor

If I use 1.5 HP of the submersible pump well what size of generator need for it? What difference between externally regulated and internally regulated? how can I notice its difference?

[@mariaabogado1036]

I have 2 Hp submersible pump what is the size or hp generator I can used?

[@danondiek439]

What will my generator rating be for 1. 110 KW motor. 2. 150KW motor?

[@mohammadhaseeb7985]

I got confused with your note.. For single phase 3 hp motor, what size of generator needed??

[@RCworstwater]

Is it a submersible pump motor with a control box or a 2-wire above-ground motor?

[@mohammadhaseeb7985]

@@RCworstwater Thanks for your reply.... This motor is induction motor which is in piston compressor

[@mohammadhaseeb7985]

This is above ground motor

I've driven by R.C. Worst in Spokane for many years. Each time I drive by I wonder what R.C. Worst sells or does??????? The sign on the street has only one hint "Expect the best from R.C. Worst". That's it! You guys seem like a cool company and a great resource. Why not make it clear what business you're in instead of keeping it a secret? I'm serious... I've been so curious at times that I've just about stopped my car and walked in the building just to ask what the hell you guys do?

[@bigpardner]

How do you know the size of your well pump motor?

[@RCworstwater]

Check the control box if you have one. If you don't you may need to check with the installer or check the amperage of the motor as a last resort.

@@RCworstwater Thank you for your kind reply. Can the size pump be guesstimated by timing on time from on to off and measuring gallons pumped? Oh, now I see this: kzbin.info/www/bejne/mYjOpIGZitaKmqc
