What Is a Hydraulic Pump?

A hydraulic pump is a mechanical device that converts mechanical energy into hydraulic energy. In simpler terms, it creates fluid flow and pressure that powers hydraulic machinery, such as cylinders, motors, and valves used in various industrial and mobile applications.

Hydraulic pumps are critical in systems requiring high force or torque in compact and efficient packages—making them essential in industries like manufacturing, construction, marine, mining, and energy.

How Do Hydraulic Pumps Work?

Hydraulic pumps operate by pulling hydraulic fluid from a reservoir and forcing it through the system under pressure. This pressure moves actuators, like pistons and hydraulic motors, creating mechanical movement and power.

Common types of hydraulic pumps:

• Gear Pumps – Simple, durable, and cost-effective

• Vane Pumps – Quiet and efficient for medium pressure

• Piston Pumps – High-performance and capable of handling high pressure and variable flow
