HYDRAULIC PUMP for HITACHI EX300 | Partsdic®
Regular maintenance and care are essential to ensure the optimal performance and longevity of the hydraulic pump. This includes monitoring the fluid level and quality, inspecting for leaks, and changing the hydraulic filters at recommended intervals. Proper maintenance practices help prevent premature wear and damage to the pump, minimizing downtime and costly repairs.
HYDRAULIC PUMP, for HITACHI EX300 | Partsdic®

The Hitachi EX300 hydraulic pump is designed to convert mechanical power into hydraulic energy.


It consists of several key elements, including an input shaft, a rotor, a set of vanes or pistons, and a housing. The pump is typically driven by the machine's engine through a power take-off or a dedicated hydraulic pump drive.

The input shaft connects the pump to the power source, usually the engine crankshaft, transmitting rotational motion to the pump's internals. As the shaft rotates, it drives the rotor within the pump housing. The rotor may have either a set of vanes or pistons that move in and out within their respective chambers. These vanes or pistons are responsible for creating the pumping action.

When the rotor turns, the vanes or pistons move outward due to centrifugal force or hydraulic pressure, respectively. As they move outward, they create expanding volumes within the pump's chambers. This expansion leads to a drop in pressure, which allows hydraulic fluid from the machine's reservoir to enter the pump. The hydraulic fluid fills the expanding chambers, and as the rotor continues to rotate, the vanes or pistons force the fluid towards the outlet ports.

The fluid, under pressure, is then directed to the various hydraulic circuits of the Hitachi EX300 excavator. It supplies power to the machine's hydraulic cylinders, controlling the movement of the boom, arm, and bucket. Additionally, the pump provides hydraulic force to operate auxiliary attachments, such as hydraulic breakers or grapples.

Efficiency and performance are crucial factors in the design of the Hitachi EX300 hydraulic pump.


It should deliver an adequate flow rate and maintain a consistent pressure to ensure smooth and precise operation of the machine. The pump's design must also consider the working conditions of the excavator, such as high temperatures, heavy loads, and continuous operation, to ensure its durability and reliability.

Regular maintenance and care are essential to ensure the optimal performance and longevity of the hydraulic pump. This includes monitoring the fluid level and quality, inspecting for leaks, and changing the hydraulic filters at recommended intervals. Proper maintenance practices help prevent premature wear and damage to the pump, minimizing downtime and costly repairs.
