If you can manage to figure out if a grundfos SQ 3” pump works for your water usage I’d go down that road. Soft start pump. Doesn’t weigh a ton. Stainless steel impellers and computer driven. The SQE with a box can give you constant pressure as well. More on reddit.com

You don't want the connection on he cord to be under water- that will trip your breaker. Check to see if you can open the pump to expose where the wires terminate- make sure you can do it without damaging seals or gaskets. Then you can buy the same size cord and make it the length you need. More on reddit.com

We sell Berkeley almost exclusively and a 0.50 HP 10 GPM Berkeley MS-series is what, if you hired me to do the work, I would install in your well. Installed at ~80’ will be right in the sweet spot of the pump curve. The part number is B10P4MS05231 for the 3-wire motor. With that being said, Gould’s, Flint & Walling, Franklin Electric’s sub brands (FPS, Schaefer, J-class), Grundfos (I don’t really like their 4” pumps but the 3” SQE with the CU301 constant pressure controller are pretty sweet) are all very solid options too. Make sure your pressure tank is sized properly for the output of your pump. For something in the 8-12 GPM range you’ll need a 35-gallon or larger tank. I recommend Flexcon’s WR and FL series or Amtrol’s WX series. More on reddit.com

Hello friend, Biggest difference is impeller material. I would avoid plastic at all costs with that type of service, as long term usage produces heat with deforms plastic. Some reputable brands (shop around though) are Goulds and Grundfos. I’m not sure if you have a hydro tank, but I’d recommend as it will greatly extend the lift of your pump. How long has your current pump been installed? More on reddit.com
