5 Best generators for well pumps reviews

People who are more experienced with well pumps and generators could be able to choose with the list of top picks and the performance table.

That being said, you will likely find it easier to pick out the best well pump generator for your situation after checking out the reviews below.

1. WEN DF475T – Best generator for standard well pumps

The WEN DF475T is our top pick for the best standard well pump generator thanks to its 240 volt outlet, dual fuel feature, budget-friendly price, and reliability.

If you rely on a well pump as your main water source, you want to make sure you get a generator that works when you want it to.

WEN DF475T

There are a few cases of finding the first few recoil starts challenging but the WEN DF475T tends to satisfy customers in this area.

  • WEN DF475T offers 4750 starting watts, 3800 running watts, 30 amps, and 240 volts (gasoline)
  • Dual fuel feature allows you to run on propane (LPG) too
  • Good run time of 11 hours at 50% load
  • Weight of 105.8 lb (48 kg)
  • Has electric start
  • Four GFCI outlets
  • Relatively positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • 15% THD is not suited for running sensitive electronics
  • Noise levels of 71 dB are somewhat louder
  • Shipping bolts can be hard to remove
  • A few exceptional cases of challenging starts

Something you do want to know is that the WEN DF475T is not an inverter.

This means you only want to use its power for your well pump or similar more robust devices. Not sensitive electronics.

Additionally, the noise levels of 71 dB are on the louder side. Your ears and neighbors may not enjoy themselves while you use your well pump.

In short, if you don’t mind the 14% THD power and noise levels, the WEN DF475T is a great generator for a standard well pump.

Especially if you consider the reliability and budget-friendly price.

2. Champion 201067 9000 – For well pump & additional electronics

Two of the main things that stand out in the Champion 201067 9000 from the other well pump generators are the inverter technology and power capacity.

Additionally, it is hard to find large inverter generators that are as reliable and reasonably priced as the Champion 201067 9000.

The low THD inverter power allows you to run sensitive electronics safely and could even cause less wear and tear to your well pump.

With the 9000 starting watts, 7250 running watts, and 50 amps, you should have enough power to run many other appliances and tools too.

Pros

  • Champion 201067 9000 offers 9000 starting watts, 7250 running watts, 50 amps, and 240 volts
  • Run time of 10.5 hours at 25% load
  • Less than 3% THD
  • Electric start
  • CO sensor
  • Four GFCI outlets
  • Weight of 152.2 lb (69 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Run time is not the most impressive
  • If you only want to run a standard well pump this is too much power
  • Noise levels of 72 dBA are somewhat louder
  • Pricier than other well pump generators

As you can likely tell, a potential downside is that the Champion 201067 9000 can also be a bit too much in terms of power and price for people who only want to run a well pump.

The noise levels of 72 dBA that come with this much power could also be too annoying for you and your neighbors.

At the same time, it is worth noting again that the Champion 201067 9000 is one of the top options when it comes to big power outage inverter generators.

If you want a generator you can rely on for a lot of clean THD power, this option can be worth the extra investment.

3. Westinghouse wGen5300DF – Best generator for 2 HP or 3 HP well pump

To run stronger well pumps of 2 HP or 3 HP, you generally want to play it safe and get some extra watts over what the top pick generator offers.

Within this category of options, the Westinghouse wGen5300DF will generally be the best choice thanks to its dual fuel feature, good reliability, and reasonable price.

Westinghouse wGen5300DF

You do want to keep in mind that the Westinghouse wGen5300DF is another well pump generator with high THD power that is not suited for sensitive electronics.

4. Champion 201047 2400 – Best generator for 120 volt well pump

Because standard well pumps tend to need at least 240 volts to function, most of the generators on this list are relatively big.

That being said, it is also possible that you have a 120 volt well pump.

In that case, this Champion 201047 2400 can be good enough and a more budget-friendly source of clean THD power.

Especially if you don’t mind switching a few appliances and tools on and off in specific orders and/or depending on when you need them.

Pros

  • Champion 201047 offers 2400 starting watts, 1800 running watts, 20 amps, and 120 volts

  • Dual fuel feature allows you to run on propane (LPG) too
  • Relatively low noise levels of 53 dBA
  • Nice run time of 11 hours at 25% load
  • Less than <3% THD
  • Light weight of 50.5 lb (22.9 kg)
  • Very positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • Budget-friendly

Cons

  • You may need more power
  • A few cases where the first model customers got did not function as desired

Another benefit of going for a smaller generator like the Champion 201047 2400 is that it is very light.

This good portability can be useful for somewhat older individuals who may find the other options too challenging to move.

However, people who just want to use their generators for other things like camping could find the light weight helpful too.

On top of all these things, the Champion 201047 2400 has a dual fuel feature too.

The extra flexibility of being able to run on propane could save you and your well pump activities in some situations.

5. Champion 201169 8125 – Best natural gas generator for well pumps

Many of the best generators for well pumps have a dual fuel feature so you have more ways to keep an important device like this going through power outages.

However, you can take this even one step further with the tri fuel Champion 201169 8125 that can run on natural gas too.

This fuel type could be extra convenient for your house or off-grid living location.

In the category of the best tri fuel generators, the Champion 201169 8125 is the most reliable option too (although you do want to give your model a try when you first get it).

Pros

  • Champion 201169 offers 8125 starting watts, 6500 running watts, 30 amps, and 240 volts (gasoline)
  • Good run time of 12 hours at 50% load
  • Weight of 197 lb (89.4 kg)
  • Has electric start
  • Four GFCI outlets
  • CO sensor
  • Very positive customer reviews

  • Budget-friendly

Cons

  • High THD is not suited for sensitive electronics
  • Very exceptional cases where customers got a suboptimal first model
  • You may not need this much power
  • Noise levels of 74 dBA are somewhat louder

By now you may understand that the 8125 starting watts and 6500 running watts of the Champion 201169 8125 are enough to run a relatively big well pump (and typically more).

Additionally, the electric start makes it convenient for elderly individuals or just people who don’t like recoil start to get the generator going.

Besides the exceptional cases where customers got a suboptimal first model, you mainly want to keep the high THD and noise levels of the Champion 201169 8125 in mind.

That being said, when it comes to reliable well pump generators that can run on natural gas, this will likely still be the best option for you.

FAQ

How big of a generator do I need for a well pump?

How big of a generator you need for a well pump depends a lot on the size and power of your specific well pump.

That being said, because well pumps often require around 230 volts to function, you will need a generator with outlets that can handle this.

In turn, you will often need a 4500+ peak watt generator or stronger models since 240 volt outlets start to become more common around this power capacity.

Can I run my well pump with a portable generator?

If the portable generator is strong enough and you follow the safety guidelines, you should be able to run a well pump with it.

How many watts does a well pump use on a generator?

How many watts a well pump uses on a generator depends a lot on the size and power of your well pump.

For example, a 1/2 HP well pump could need as few as 1200 starting watts and 700 running watts after that.

Something like a 2 HP well pump could need 4000 starting watts and 2300 running watts and potentially even more.

What size generator do I need to run a 1/2 hp well pump?

Well pumps can vary in terms of power needs so you want to check the details for your individual model.

For example, a 1500 peak watt generator could be big enough to run a 120 volt 1/2 HP well pump.

However, because well pumps often require 240 volt power sources, you may have to go for a 4500 peak watt or even stronger generator.

What size generator do I need to run a 1 hp well pump?

Ideally, you want to check the well pump you are working with to make sure you have the details right.

However, you will likely need a 4500 starting watt or bigger generator to run a 1 HP well pump since you will likely need a 240 volt outlet.

If you happen to have a 120 volt 1 HP well pump, a 3000 peak watt generator could be big enough too.

What size generator do I need to run a 2 hp well pump?

To run a 2 HP well pump with a safety margin, you need a generator with 4800 peak watts or more and a 240 volt outlet.

Our top pick

It is possible that are still not entirely sure what well pump generator would be the best for you.

In that case, the WEN DF475T is often the best choice for standard well pumps thanks to its 240 volt outlet, propane compatibility, reasonable price, and other solid features.
