Charge gear pump for Terex PT70

The gear pump, part number 2045-473, serves as a component within the hydraulic transmission and auxiliary assembly of the Terex PT70. This unit is specifically engineered for machines with serial numbers starting from DTH 00682. Its primary function is to supply a consistent flow of hydraulic fluid at low pressure to the main control circuit, ensuring that the transmission pumps and auxiliary circuits remain adequately primed for operation.

By maintaining a steady supply of fluid, this component helps prevent cavitation within the hydraulic system, which supports the overall responsiveness and power of the machine's work functions. Proper charge pressure is necessary for the efficient operation of the transmission and hydraulic control systems, directly influencing the maneuverability and performance of the equipment during daily tasks.

In hydraulic systems, a charge pump acts as an auxiliary source of fluid, delivering the necessary volume to maintain system pressure and cooling. This ensures that the primary hydraulic pumps have the required intake conditions to function correctly under load. By supporting the main hydraulic circuit, this component assists in the smooth operation of the machine's various auxiliary and drive functions.
