Whether you need to pump water out of your basement this spring, or just want to have fun shooting water around in the yard this summer, here’s a way to build a pump instead of buying one. This is a simple but ingenious build, and [NavinK30] did everything shy of machining his own hardware and making his own tools. Well, it looks as if he might have made that drill.
As you’ll see in his how-to after the break, this centrifugal pump is mostly acrylic, PVC, and fasteners. [Navin] cut two sides and a base for the paddles from acrylic, and joined them with a heat-formed sidewall made of PVC. We love that he cut and bent his own paddles from sheet metal. These are bolted to a round piece of acrylic that attaches to the outside with a long hex bolt. A ball bearing mounted on the drill side allows the pump to churn freely as long as the bolt is chucked into the drill, and the hose clamp is tight enough to hold down the trigger.
Have an extra drill, but don’t need to pump water? Add a camping stove and use it to power a small-batch coffee roaster.
I did this with my cheap black and decker drill, but turned it into a peristaltic pump. I had to get gas out of my gas tank(gas was pretty much done).
You can find 3d printable(and customizable for any hose size) in thingiverse.
Such a fine way to kill motor in that drill.
Pop rivets good
Carpal tunnel bad
I had something similar for the drill. Wasn’t as effective as I thought it should be.
Yeah I had a cheap drill pump for the water beds. Wound up using the shop wet vac to drain this last time since the drill one seized for some reason. This articles design looks like better volume flow.
Respect for using the electric drill as a water pump while using hacked DC motor for an electric screwdriver to build the pump (5:20)
Was hoping for a Tesla pump.
Still would be a centrifugal pump, and perhaps less fecient.
Pretty complex build, he just had to knock that tub over…
B^)
I suppose there are dozens of prints on thingyverse for more efficient vanes and housings?
But this design does not require a 3D printer.
You are correct.
Perfect way to drill water pump. Thanks a lot for sharing
