Charge pump for Terex PT100G

The Sauer charge pump, identified by part number 2075-448, serves as a component within the hydraulic transmission and auxiliary systems of the Terex PT100G. It is manufactured by Sauer. The pump maintains a constant charge pressure within the closed hydraulic circuit, which is necessary for the operation of axial piston pumps and motors that drive the equipment. By providing a consistent supply of oil, the component supports the hydraulic system requirements of the machine.

Charge pumps are used in closed-loop hydraulic systems to replenish fluid lost through internal leakage and to provide cooling flow. They ensure that the main hydraulic pumps remain primed and operate under sufficient inlet pressure to prevent cavitation during operation. This maintenance of pressure is necessary for the transmission of power and torque in heavy machinery.
