The CAT E320D2 hydraulic pump assembly (part number 397-3680)
provides high-pressure hydraulic power to the excavator's hydraulic
system and is a core component that drives the entire machine.
Featuring a high-precision plunger design and reinforced materials,
the pump offers high pressure output, low energy consumption, and
excellent sealing, ensuring stable performance even under sustained
heavy loads.
Features and Benefits
• Stable Hydraulic Output: Precisely controls oil pressure flow to
ensure smooth and efficient excavation.
• Rugged and Durable Structure: Core components utilize reinforced
materials and precision machining to withstand extended, high-load
operation.
• High-Efficiency Energy Transmission: High energy conversion
efficiency reduces energy loss and improves overall equipment
efficiency.nergy-saving and High-Efficiency: Optimized hydraulic
transmission structure reduces energy loss and improves system
efficiency.
• Sensitive Operation: Combined with the hydraulic system control,
the pump delivers smooth, coordinated operation and more precise
operation.
• Extended Maintenance Intervals: Wear-resistant components and
superior sealing reduce failure rates and maintenance frequency.
