Model and Applicability: The model number is 708 – 1S – 11212, applicable to Komatsu PC35MR2, PC55MR – 2, PC50MR – 2, PC45R – 8, PC45 – 8, PC40, and PC40MR – 2 excavators1.
Performance Parameters: There is no publicly available specific data on displacement, rated pressure, and rated rotation speed. However, considering the working requirements of these excavators, the pump is designed to provide sufficient hydraulic power for the normal operation of the excavator's working devices. The hydraulic systems of these excavators have corresponding pressure and flow requirements, and the 708 – 1S – 11212 pump needs to work stably within this range.
Structural Characteristics: It is a K3V180DT – P1A9R – 9N05 hydraulic piston pump. It likely belongs to the axial – piston pump type5. Axial – piston pumps have the advantages of high efficiency and good variable – displacement performance, which can meet the requirements of different working conditions of excavators. The pump body is made of high – strength alloy steel or cast iron, which has good wear – resistance and corrosion – resistance. The internal moving parts, such as pistons and swash plates, are made of wear – resistant materials to ensure a long service life. The pump weighs 219 kg, and the wooden box packaging size is 86x57x57 cm5.
