Product Description

This hydraulic main pump is the power core assembly of the hydraulic system for the EC140, EC210, EC210B, and EC240 series excavators. As the source of hydraulic power for the entire machine, it converts the mechanical energy of the engine into high-pressure and large-flow hydraulic oil, providing a stable pressure oil source for the arm, bucket arm, bucket, slewing motor, and traveling motor. It directly determines the digging force, action response speed, coordination of compound actions, and overall operating efficiency of the entire machine.

This hydraulic pump adopts a double-rod axial piston pump structure. The pump housing is formed by casting high-strength cast iron as a single piece and undergoes aging stress relief treatment. It can withstand alternating high-pressure impacts for a long time and effectively avoid shell deformation, oil leakage, and cracking problems. The core friction pairs such as the cylinder body, piston, flow distributor plate, and swing assembly are all made of high-maintenance alloy materials. They are strengthened through forging, heat treatment, and paired grinding processing, precisely controlling the internal clearance, minimizing internal volume leakage under high-pressure conditions, maintaining a high volumetric efficiency, and improving the sluggishness of actions after the equipment is heated. The pump body integrates a complete set of negative flow variable regulator components, which can dynamically adjust the output displacement of the dual pumps in real time according to external loads, perfectly matching the overall negative flow hydraulic control system, achieving a reasonable distribution of load and power, balancing the explosive force of the excavation operation and fuel economy, and being compatible with various working conditions such as ordinary earthwork and continuous impact from the breaker hammer.
