A water pump is one of those items that are uncommonly used, but invaluable when needed. Rarer still are cordless versions that can be deployed at speed. Enter [DIY King 00], who has shared his build of a cordless water pump!
The pump uses an 18 volt brushed motor and is powered by an AEG 18V LiPo battery. That’s the same battery as the rest of [DIY King]’s power tools, making it convenient to use. UPVC pipe was used for the impeller — with a pipe end cap for a housing. A window of plexiglass to view the pump in motion adds a nice touch.
A bit of woodworking resulted in the mount for the pump and battery pack, while a notch on the underside allows the battery to lock into place. Some simple alligator clips on the battery contacts and the motor connected through a switch are all one needs to get this thing running.
Unfortunately, the motor is seen smoking a bit at the end of the video, the result of a slightly oversized impeller causing the motor to draw too much current. Still — for a short while at least — this thing can spit 10L of water per minute up to 10 feet away! Not too shabby!
This pump would certainly come in handy for any water-related emergencies, but if you want to nip that problem in the bud before it gets out of hand, check out how you can rig up your home’s sump pump to alert you of any impending crises.
