There is an ample stock of goods in stock, and once you place an order, the order will be quickly processed and dispatched. There is no need for long waiting periods.

The entire machine undergoes strict pressure testing upon leaving the factory, ensuring stable quality. At the same time, we provide comprehensive after-sales warranty, and the technical team will follow up throughout the process. Maintenance inquiries can be responded to at any time.

Product Description

This EC210B hydraulic main pump is the power core of the entire hydraulic system of the excavator. It is a major component of the power source of the entire machine, converting the mechanical energy output by the engine into high-pressure hydraulic oil energy, providing pressure oil flow to the boom, bucket arm, bucket, slewing motor and traveling motor. The digging output force, the speed of action response, the smoothness of compound actions, as well as the power matching effect of the entire machine, all rely on the stable operation of the hydraulic pump to be achieved.

The hydraulic pump adopts a double-axial piston pump structure. The pump body shell is made by casting high-strength cast iron as a whole and undergoes aging treatment to eliminate internal stress, effectively avoiding the problem of shell deformation and leakage caused by long-term high-pressure operation. The core frictional components such as the cylinder body, piston, flow distributor plate, and swing assembly are made of wear-resistant materials. They undergo precise grinding and matching grinding processes, strictly controlling the internal clearance, minimizing internal volume leakage under high-pressure conditions, and maintaining the output efficiency of the pump for a long time, alleviating the phenomenon of weak thermal machine action in the later stage of equipment use. The pump body integrates a complete set of negative flow variable regulator assembly, which can dynamically adjust the output displacement of the dual pumps in real time according to the load changes, perfectly adapting to the entire machine's negative flow hydraulic control system, achieving a reasonable matching of engine power and hydraulic power, reducing the problem of stalling and deceleration under heavy-load conditions, and balancing the excavation force and fuel consumption performance, suitable for various construction site conditions such as earthwork excavation, river channel dredging, infrastructure crushing, etc.
