What is the role of a hydraulic pump?

The role of a hydraulic pump is fundamentally to convert mechanical energy into hydraulic energy. This process involves the pump drawing hydraulic fluid from a reservoir, increasing its pressure and flow rate, and then transferring this pressurized fluid to various actuators and components within the hydraulic system.

By operating in a closed loop, the hydraulic pump transforms the energy provided by an external source (such as an electric motor or diesel engine) into potential energy of the fluid, which can then be utilized for various tasks, such as moving machinery or lifting loads. This transformation is essential for the functionality of hydraulic systems, making the pump a crucial component that powers the hydraulic circuit.

In contrast, filtering hydraulic fluid focuses on maintaining fluid cleanliness, regulating pressure pertains to controlling the pressure levels within the system, and providing cooling addresses thermal management, which are all important functions but do not define the primary role of the hydraulic pump itself.
