In closed loop circuits, the return line (i.e. the suction line of the pump) is under pressure. This must be incorporated in the design of axial piston units used in closed loop systems. It is also imperative to have a variable displacement volume hydraulic pump in operation in these systems.
When you use a pilot-operated, electro-hydraulic controlled pressure or flow regulator, the outflow of the pump depends on system pressure, flow or a combination of both (i.e. power control). If the hydraulic system pressure reaches above a predetermined pressure setting, the flow of the pump returns to zero and the system pressure is maintained constant.
By doing so, the power lost in the system is low and the energy consumption of the drive system is minimal at maximum pressure. Note that a combination of flow and pressure regulation permits designing very economic drives (e.g. load sensing).
Hydraulic pumps are manufactured depending on different functional and hydraulic system requirements, such as operating medium, required range of pressure, type of drive, etc. Our sales engineers will assist you in selecting the most appropriate hydraulic pump for your application.
