Venturi Well Injector

This is a basic Venturi injector for a well. I have a shallow well with a 4" casing that was filled with a five foot (1.5 meter) slurry of sediment and I needed a way to remove it.

This concept is redesigned from this project (https://www.thingiverse.com/thing:209069). The original was created in OpenSCAD and utilized EU standards, the revision was redrafted in OnShape US standards and a smaller form factor (https://cad.onshape.com/documents/59164ea1b5ce597778acc108/w/41042df3d23fef510f9faf89/e/a0ff54b3440f9018ca8e31e0).

Major modifications and reason for the redesign, it was adjusted to fit a 1.25" pipe and standard 3/4" garden hoses (common US). Max width was also reduced to 3" so it would easily fit down the 4" inside diameter of a well casing. I also added holes for two 1/4x3/4" bolts. These are dual purpose, I found the pump would get stuck to the bottom of the hole or pull itself into the thicker parts of the slurry. The bolts allow me to stand the pump off a bit,
