When it comes to hydraulic pumps, here is some further information:

Types of displacement pumps:

Gear pumps: Gear pumps are one of the most common types of displacement pumps. They consist of a pair of meshing gears that draw in and deliver fluid through the gaps between the gears. Gear pumps have a simple structure, small size, and are suitable for applications with medium flow rates and moderate pressures.
Piston pumps: Piston pumps deliver fluid through the reciprocating motion of pistons. They typically have higher working pressures and flow capacities, making them suitable for high-pressure systems and applications that require higher performance.
Screw pumps: Screw pumps move fluid by the engagement of a screw and the threaded housing. They are suitable for viscous fluids and media with a higher content of solid particles, such as lubricating oil and concrete.
