Charge pump for Terex RT 335

The charge pump is a component within the hydraulic system of the Terex RT 335 rough-terrain crane. Its primary function is to maintain constant pressure in the suction circuit of the main hydraulic pump, compensating for internal system leakage and ensuring the main pump receives sufficient fluid for operation. Additionally, this pump supplies the pilot or control circuit, which governs the movement of the crane's valves and actuators.

This component is compatible with the Terex RT 335 model. It is designed to integrate into the machine's closed-loop hydraulic system to prevent cavitation and ensure consistent fluid delivery to the main pump assembly. Proper operation of this pump supports the crane's ability to perform precise lifting, slewing, and boom extension maneuvers.

In hydraulic systems, a charge pump typically utilizes a gear or vane design to provide a steady flow of pressurized fluid. By maintaining the required charge pressure, the pump protects the main hydraulic pump from cavitation and ensures that control signals remain responsive. Regular monitoring of charge pressure is standard practice to maintain the efficiency of the hydraulic circuit and prevent premature wear of major system components.
