What is the function of a hydraulic pump in a hydraulic system?

The function of a hydraulic pump in a hydraulic system is indeed to convert mechanical energy into hydraulic energy. This process involves the pump drawing in hydraulic fluid and pressurizing it, thereby transferring the energy needed to perform work in the system. This transformation is critical for the operation of hydraulic systems, as it allows for the movement and control of machinery and tools through the use of pressurized fluid, enabling tasks such as lifting, pushing, or steering.

While other components in a hydraulic system may serve functions such as storing hydraulic fluid or regulating pressure, the pump's primary role is fundamentally linked to the conversion of mechanical input into hydraulic output. This conversion is essential for the functioning of hydraulic systems across various applications, including construction, manufacturing, and automotive industries.
