China EX120-2 SWING MOTOR hydraulic pump parts | Partsdic®

The EX120-2 swing motor hydraulic pump is a variable displacement axial piston pump.

This type of pump is known for its efficiency and ability to adjust its output to meet the specific demands of the hydraulic system.

Flow Rate:
The flow rate of the hydraulic pump is a critical specification. It determines how much hydraulic fluid the pump can deliver per unit of time. The flow rate for the EX120-2 swing motor hydraulic pump typically ranges from 60 to 100 liters per minute (LPM). This range ensures that the excavator can perform a wide range of tasks with varying hydraulic power requirements.

Pressure Rating:
Hydraulic systems operate under high pressure, and the pump must be capable of generating the required pressure. The EX120-2 swing motor hydraulic pump usually has a pressure rating of around 3000 to 3500 psi (pounds per square inch). This high pressure enables the excavator to perform heavy-duty digging and lifting operations.

Displacement Control:
The pump is equipped with a displacement control mechanism that allows the operator to adjust the flow rate and pressure according to the specific task at hand.

This feature ensures efficient operation and minimizes energy wastage.

Construction Material:
The components of the EX120-2 swing motor hydraulic pump are typically made from high-quality materials, such as hardened steel and durable seals, to withstand the demanding conditions of construction and excavation work. This ensures longevity and reduces maintenance requirements.

Mounting and Compatibility:
The pump is designed to be compatible with the Hitachi EX120-2 excavator model and can be easily mounted in the hydraulic system of the machine. Proper compatibility ensures seamless integration and optimal performance.
