Double gear pump for Grove RT 765 E2

The piggyback double gear pump, part number 80029457, serves as a hydraulic component in heavy machinery. Its function involves converting mechanical rotational energy from the engine into hydraulic energy, generating fluid flow at pressure to power various actuators and systems within the crane. The piggyback configuration consists of two gear pumps mounted in tandem, allowing the unit to supply flow to two independent hydraulic circuits or a single circuit requiring higher volume. This setup allows for the simultaneous operation of different crane functions, such as lifting, boom extension, steering, and stabilization.

This component is designed for the Grove RT 765 E2 rough-terrain crane. Gear pumps operate by using a pair of gears rotating within a housing to create a vacuum at the inlet and force fluid toward the outlet under pressure. The pump is engineered to meet the specific flow and pressure requirements of the Grove hydraulic system, ensuring proper integration with the machine's existing architecture. Regular maintenance of the hydraulic system is necessary to prevent loss of pressure or flow, which can lead to slow or erratic movement of crane functions.
