What is a water pump?
Water pumps are machines used to move water. There are different types suited different applications. They vary in sizes from small portable pumps for everyday use at home to large industrial pumps for supplying feed water to power plants.
For residential, the most common ones include pumps for sprinklers, wells, sumps, pools, and ponds.
Conclusion
A 100 GPM pump is considered pretty powerful but sometimes they’re just what we need. Allowing us to do the job effectively and easily.
These were the ones I found that outperform the others when it comes to pumping 100 gallons of water in a minute. I’ve tried my best to find one for each occasion but I’m sure I missed some of them. Make sure to tell us about others we should include in the comments below!

How about a 10 HP 230V /60 cycle Submersible Pump and Motor’ to pump 140 PSI & 100 GPM clear Lake water into our 4 inch Irrigation line. This unit is placed about 3 feet below the lake surface.
Hi Les, this pump is the closest I could find. Here’s the pump curve for this model (seems like the build.com specs isn’t exact.) If you want to try sizing yourself, you can try using Grundfos’ site here.
