Excavator Hydraulic Main Pump 311-9542 3119542 10R1457 247-8975 185-0220 for Caterpillar 345B ,High-Quality Hydraulic Pump,Construction Machinery Parts Manufacture

 

The hydraulic pump models 311-9542, 3119542, 10R1457, 247-8975 and 185-0220 are primarily used to provide power for various operations of excavators. Its core functions include:

• Core Power Output - As a key component of the hydraulic system, it adopts a piston/variable pump structure with high-pressure and high-flow design. Provides stable power for excavation, slewing, traveling and other operations, adapting to complex working conditions and long-term high-intensity work.
• Quick Fault Response - For common issues such as insufficient oil suction, inadequate flow or pressure abnormalities, efficient troubleshooting can be achieved by checking oil level, cleaning pipelines, repairing leaks, inspecting relief valves or adjusting the variable mechanism.
• Convenient Maintenance Guarantee - Regularly check the hydraulic oil level, quality and cleanliness, promptly replace contaminated or deteriorated hydraulic oil; clean or replace the oil suction filter to avoid clogging affecting oil absorption; inspect the hydraulic pump's connecting pipelines and joints to prevent leakage; follow Caterpillar's official maintenance manual for regular inspection and maintenance to ensure reliable operation of the equipment.
