A hydraulic pump is an essential component in hydraulic systems, providing pressurized liquid to power various mechanical operations. It converts the mechanical energy of power machines (such as electric motors and internal combustion engines) into the pressure energy of a liquid, typically hydraulic oil. This conversion process allows the hydraulic system to perform tasks such as lifting, pressing, and moving heavy loads.
Hydraulic pumps can be classified into three main types: gear pumps, vane pumps, and piston pumps. Each type has its own characteristics and is suited for different applications.

Choosing the right hydraulic pump for a specific environment depends on several factors:
Selecting the appropriate hydraulic pump involves considering the specific requirements of the application, including pressure, flow rate, contamination resistance, noise levels, and efficiency. Each type of hydraulic pump—gear, vane, or piston—has its unique advantages and is suited for different environments and operational demands. Proper selection ensures optimal performance, longevity, and reliability of the hydraulic system.
