What is a drill pump?
A pump that is powered by attaching the main pumping mechanism to an electric power drill. They come in many shapes and sizes, and they are made by many commercial tool companies for small-scale residential, commercial, and industrial use. They're inexpensive, with some of the smaller types costing $10 or less.
How do they work?
The construction of a drill pump is simple. There is a center piece with a clearly marked intake and outlet side. The center piece is usually circular, and one side of the circle contains a mechanism that can be attached to the head of an adjustable power drill. Some come with built-in hoses. Others require you to buy hoses separately. Once the drill is turned on, a small impeller within the pump begins spinning, which draws the fluid through the intake and pushes it out through the outlet. Drill pumps are limited by the power of the drill, and they can only handle small volumes of fluid.
Where are they used?
Drill pumps are useful for a variety of applications, including emptying clogs, changing oil, draining tanks, or pumping water out of pits or wells.
