Hydraulic presses are machines that use a hydraulic cylinder to generate compressive force. By utilizing hydraulic fluid, they can exert large forces on workpieces, making them ideal for tasks such as metal forming, molding, and assembly. The efficiency and effectiveness of hydraulic presses heavily depend on the hydraulic pump used to drive them.

There are several types of hydraulic pumps commonly employed in fluid power systems:
Gear Pumps: These are among the most widely used hydraulic pumps. They consist of a pair of gears that pump hydraulic fluid. Gear pumps are simple in design, offer a consistent flow, and are best suited for high-pressure applications.
Piston Pumps: Piston pumps use one or more pistons to compress the hydraulic fluid. They can achieve higher pressures compared to gear pumps, making them suitable for applications requiring high force. Piston pumps can be categorized into fixed displacement and variable displacement types, providing flexibility based on operational needs.
