Electric pump alongside deep well pump?

[2Deep]

Is there a way this can be done? I've been looking hard to find answers and help,
but so far haven't been successful.

My well is ~125-150' deep, and I have a Simple Pump installed that goes down ~99'. I'm
pretty sure the water table is around 75'. The well casing is 4" in diameter.

I would really like to be able to install an electric pump alongside, and I don't want to
motorize the simple pump.

Can't get any help from Simple Pump? Looks like exactly what that pump should be capable of. Shows the smallest barrel at 1.37". Using 1" pipe for the submersible, and having set the submersible first, there should be room to set the barrel just above the submersible pump. 1" drop pipe will measure close to 1.5". It will be a tight fit in the 4" casing but both the 1.5" drop pipe and the 1.37" Simple Pump barrel should fit. Looks like they even make a two hole well seal to hang both pipes.

You could remove the hand pump, drop a 4" submersible down to 100+ ft, then put the hand pump back in to 99 feet.
The discharge tube for the submersible will have to be whatever size tube will fit next to the hand pump suction tube in the bore casing.

You could also screw the submersible to the foot valve on the Simple Pump. The sub will push water through the Simple pump pipe. The Simple pump can then draw water through the submersible when needed. We use to do windmills this way for an electric backup for when the wind wasn't blowing and the cows were thirsty.
