Buy Main Hydraulic Pump For Ex120-1 Hitachi Excavator Hydraulic Pump For Excavator | Partsdic®

The main hydraulic pump for the Hitachi EX120-1 excavator is typically a variable displacement axial piston pump.

This type of pump allows for adjusting the flow rate and pressure output to meet the specific requirements of various excavator functions. The variable displacement feature ensures efficient operation and energy conservation.

Flow Rate and Pressure:
The exact flow rate and pressure specifications of the hydraulic pump may vary depending on the specific model and configuration, but a typical EX120-1 hydraulic pump is designed to deliver a flow rate of around 200 liters per minute (LPM) and a pressure rating of approximately 34.3 MPa (4,975 psi). These parameters ensure that the excavator can perform a wide range of tasks effectively.

Efficiency and Control:
The main hydraulic pump is equipped with advanced control systems to optimize its efficiency. It often incorporates features like load-sensing and pressure-compensated controls, which adjust the pump's output in real-time to match the requirements of the excavator's hydraulic circuits. This not only improves performance but also conserves energy, reducing fuel consumption.

Hydraulic Fluid Compatibility:
The hydraulic pump is designed to work with hydraulic fluids that meet specific specifications to ensure smooth operation and longevity. It's important to use the recommended hydraulic fluid and regularly maintain its quality to ensure the pump's durability and reliability.

Durability and Reliability:
Given the demanding nature of excavator operations, the main hydraulic pump is built to withstand heavy usage.

It is typically constructed with high-quality materials and precision engineering to ensure long-lasting performance in challenging environments.

Installation and Compatibility:
The hydraulic pump is designed to seamlessly integrate with the Hitachi EX120-1 excavator's hydraulic system. It is crucial that the pump is installed by trained technicians and is compatible with the machine's overall design and components.

Maintenance and Service:
Routine maintenance and servicing of the hydraulic pump are essential to ensure its continued reliability and performance. This may include regular checks, fluid changes, and occasional repairs or replacements as necessary.

Importance in Excavator Operations:
The main hydraulic pump is the heart of the excavator's hydraulic system. It powers the various hydraulic cylinders and motors that drive the machine's movements, making it indispensable for digging, lifting, and other excavator functions. A well-maintained and efficient pump directly impacts the excavator's productivity and the operator's ability to control the machine with precision.
