Komatsu Excavator Hydraulic Pump PC128 Pc128uu-1 | Partsdic®
The PC128 and PC128UU-1 excavators also incorporate safety features into the hydraulic pump system. These include pressure relief valves and overload protection mechanisms. The pressure relief valves prevent the system from exceeding safe pressure levels, safeguarding the pump and other hydraulic components from potential damage. The overload protection mechanisms detect excessive loads and automatically adjust the pump's output to prevent overstraining, protecting the excavator from potential failures.
Komatsu Excavator Hydraulic Pump, PC128 Pc128uu-1 | Partsdic®

The hydraulic pump on these excavators is a variable displacement piston pump, specifically designed to deliver optimal performance and efficiency.


It utilizes the latest hydraulic technology to ensure smooth and precise operation. With a variable displacement feature, the pump adjusts the flow of hydraulic fluid based on the demand, allowing for efficient power distribution and reducing unnecessary energy consumption.

The hydraulic pump on the PC128 and PC128UU-1 has a maximum flow rate of around XX liters per minute (replace "XX" with the actual value). This high flow rate enables the excavator to perform heavy-duty tasks with ease, such as digging, lifting, and loading large amounts of material. It ensures that the hydraulic functions operate at their full potential, maximizing productivity on the job site.

The pump is driven by the excavator's engine through a dedicated power transmission system. This setup ensures a consistent supply of power to the pump, enabling it to deliver the required hydraulic pressure and flow for various tasks. The power transmission system is designed to minimize energy loss and maximize the efficiency of power transfer from the engine to the hydraulic pump.

To maintain optimal performance and longevity, the hydraulic pump is built with high-quality materials and undergoes rigorous testing and quality control measures during the manufacturing process.


It is designed to withstand the demanding conditions of construction and excavation sites, ensuring durability and reliability in the long run.

The hydraulic pump features advanced control mechanisms, such as pressure compensation and load-sensing technology. These features allow the pump to adapt to varying loads and pressures, ensuring smooth and consistent operation regardless of the task at hand. The pressure compensation feature maintains a constant pressure level, while load-sensing technology adjusts the pump's output based on the load requirements, optimizing efficiency and minimizing unnecessary power consumption.

The PC128 and PC128UU-1 excavators also incorporate safety features into the hydraulic pump system. These include pressure relief valves and overload protection mechanisms. The pressure relief valves prevent the system from exceeding safe pressure levels, safeguarding the pump and other hydraulic components from potential damage. The overload protection mechanisms detect excessive loads and automatically adjust the pump's output to prevent overstraining, protecting the excavator from potential failures.
