This pump is integral to the hydraulic systems that support braking, steering, and suspension mechanisms in commercial trucks.

Basic Concepts of Hydraulic Pumps

Hydraulic pumps are devices that convert mechanical energy into hydraulic energy. They operate by drawing fluid from a reservoir and pressurizing it to drive hydraulic actuators. These actuators, in turn, perform mechanical work. Key components of a hydraulic system include the pump, reservoir, actuators, and control valves. The pump plays a role in generating the necessary pressure for the system, while the reservoir stores the hydraulic fluid. Actuators convert hydraulic energy into mechanical motion, and control valves regulate the flow of fluid to the actuators ¹.
