Hydraulic pumps are devices used to convert mechanical energy into hydraulic energy by moving fluid through a hydraulic system. These pumps are essential components in various applications, including industrial machinery, construction equipment, and automotive systems. By creating fluid flow, hydraulic pumps enable the operation of hydraulic cylinders, motors, and other actuators, facilitating tasks like lifting, pushing, and rotating with precision and power. They come in various types, such as gear, piston, and vane pumps, each suited to specific performance requirements and operating conditions.
