A motor pump is a mechanical device that uses an electric motor to compress air or liquid. It is used to move fluids under pressure, such as water in a sprinkler system or hydraulic fluid in a hydraulic system. Motor pumps are available in several configurations, including:
A hydraulic motor pump uses an electric motor to drive a piston into an enclosed oil-filled cylinder. The piston compresses the oil and forces it out through the discharge port. The compressed oil then pushes against the sidewall of the cylinder and turns it into motion. This motion can power other equipment, such as a jackhammer or loader.
An electric motor pump uses an electric motor to drive a plunger (or piston) into an enclosed chamber filled with air or liquid. The plunger compresses the air or liquid and forces it out through one or more discharge ports located on top of the housing unit. These ports are connected to tubes that lead outdoors where they are used to move water or other fluids from one location to another.
