Liquid Pumps
Liquid pumps are used to move fluids from one location to another. Like all pumps, liquid pumps rely on pressure to move liquids from an area of high pressure to an area of low pressure. This pressure is generally created by a piston that moves in and out of a cylindrical chamber. The piston is powered by an electric motor that enables its linear motion.
When the piston leaves the chamber, it becomes a vacuum that allows liquid in from the inlet line. When the piston reenters the chamber, it pressurizes the liquid. As the liquid cannot be compressed, it must be displaced, exiting through the outlet line. The inlet and outlet lines are fitted with valves so that the fluid can flow in only one direction.
Liquid pumps can carry many different fluids, but the most common applications carry water for drinking, cleaning, and irrigation purposes. Liquid pumps are used for a variety of applications and can take on many different designs. Although electric motors most commonly provide their power, liquid pumps can also be powered by solar panels, windmills, or batteries.
