Many locations rely on well pumps to provide water. Even some urban locations will use well water to provide for livestock and flora water control. However, most well pumps require electricity and when an outage occurs, it can be difficult to retrieve water even for household use as many wells are in excess of one hundred feet.
Pumps are different than household appliances, many require 240V and at least a 30A circuit to function and they have to have a generous surge capacity for when they first spin up. In general, generators for well pumps have to be reliable and powerful to get the job done.
How Deep Does It Go?
Surface wells can range from tens of feet to five hundred feet and all well require pumps to move water up from the bottom of the well to the top and out the outlet. This process requires a large about of energy even for small wells.
This energy demand can be significant for a generator. To determine the exact power requirement for your well, you take the total volts of your pump and the total amps of your pump and multiply them together and this will give you its running power demand.
Next, is the requirement of the surge capacity. Pumps have to spin up or activate and this requires the generator to be able to quickly meet this requirement. After a short time, the pump will drop back down to the running demand but that surge demand can be significant. At a minimum, a generator should have at least 1000W over the running demand but more than that adds more of a buffer. Finally, it should be a 30A circuit as a 20A or less is likely to trip with extended running and it would potentially damage your generator.
Five Great Generators For Well Pumps
Best Generator for the Money
Backed by a three-year warranty, the Westinghouse Model #WH7500E Generator is ready when you are. With minimal assembly required, this generator can be ready to run within minutes of coming out of the box. This model has four three prong outlets and a 30A twist lock which is great for use with a transfer switch.
Where this model really shines is the 9000W total surge capacity, which is 1500W over the continuous generation of 7500W, more than enough to handle even a large well pump. This model is well liked by those who use it with many remarking about how well it handles multiple surge items like sump pumps and freezers.
Ultimate Well Pump Generator
The Durostar Model #DS10000E Generator is a powerful electric generator can run a small to medium house with a transfer switch or used independently.
This model has three twist lock connections including a 30A circuit and it is electric start for fast starting. It has an onboard volt meter and this model is fully EPA approved and it comes with a spark arrestor so it can be used in national parks or in the field.
This model has a 2000W surge capacity over the continuous generation of 8000W, so you can run more than just a well pump at the same time. People who have this generator are impressed with the quality and performance of this generator.
Best Generator for the Price
The A-iPower 12,000-Watt Series Gasoline Electric Start Generator is a powerful generator can be used for a wide range of applications from emergency backup including running a well pump to being used for RV’s and more.
There are two things that really stand out about this new model for this year is that it has a large capacity of 12,000W so you can power multiple well pumps at once and more and it is a GFCI model in which all circuits are GFCI for added protection when used under less than ideal conditions.
It is electric start for quick starting and the unit has dual twist locks including a 30A circuit. People who use this model really love how well made this generator is and how well it performs under a variety of circumstances.
Top Rated Well Pump Generator
With a 2000W surge capacity over the 8000W continuous supply, the Champion Power Equipment Model #100297 Generator can easily handle well pumps and more. It has both a 120V 30A twist lock and a 240V/120V 30A twist lock so you can take care of more than one demand at a time. What really makes this generator shine, is that it is a dual fuel generator that is ready to run out of the box.
That means it can run on either propane or gasoline, thus giving you more options in a pinch. It has an LCD meter system and the unit has a three-year warranty and free lifetime technical support. People who have this model love the free technical support and the fact this model can use either of the two fuel choices.
Premium Well Pump Generator
With plenty of connectivity options, no one is surpised a Briggs and Stratton generator is in the top of any generator list. This Briggs & Stratton Model #30664 Generator has 2000W of surge capacity over the continuous generation of 8000W and it is electric start for fast starting.
Being a Briggs and Stratton, this model is easy to find parts for but you don’t have to worry as this model is backed by a three year warranty. Easily capable of handling a well pump and more, people who have this generator love how robust this model is and how well it works for them.
All generators can be dangerous if used improperly, therefore be sure to read and follow all safety instructions.
