20/925446 20/925743 PVB80R1HN316 Hydraulic Main Pump For JCB 8080 Excavator Hydraulic Piston Pump Construction machinery after-sales parts manufacturer

 

The piston pump models 20/925446, 20/925743 and PVB80R1HN316 are primarily used to provide stable and efficient power output for the equipment's hydraulic system, serving as key components to ensure the precise execution of core operations such as excavation, lifting and slewing. Its core functions include:

• High-pressure and heavy-load adaptation -Rated working pressure meets medium-high pressure standards, easily handling heavy-load requirements in excavation operations with high power density output, ensuring the equipment's digging force and operational efficiency.
• Energy-efficient design - Excellent volumetric and mechanical efficiency with minimal energy loss. Equipped with stepless flow regulation, it precisely matches output to load demands, achieving higher energy savings compared to traditional hydraulic pumps.
• Stable and reliable operation - Multiple plungers evenly arranged in the cylinder block enable continuous oil suction and discharge with low flow pulsation, effectively reducing system vibration and noise while extending the service life of related components such as hydraulic valves and sensors.
• Outstanding durability - Core components are made of high-strength wear-resistant materials, undergoing precision machining and hardening treatment. It boasts strong resistance to impact loads, adapts to harsh outdoor working conditions and oil temperature fluctuations, and features a long designed service life.
