Hydraulic Main Pump 627-1304 584-0380 30R-0200 576-3072 for E395GC Excavator

This hydraulic main pump, identified by part numbers 627-1304, 584-0380, 30R-0200, and 576-3072, is the primary hydraulic power unit engineered specifically for the E395GC excavator hydraulic system. It delivers high-pressure hydraulic oil to drive the boom, arm, bucket, travel, and swing assemblies.

Built on a variable piston structure, the pump combines precise flow control, wear-resistant alloy materials, and precision machining. It is designed for direct replacement installation and delivers stable output performance under heavy-duty mining and construction working conditions.

• Internal piston and valve plate wear, leading to pressure drop and weak action
• Internal seal failure, resulting in hydraulic oil leakage
• Abnormal noise and vibration during operation
• Servo piston stuck, causing flow adjustment failure
• Housing cracks caused by overload and high pressure

• Confirm the part number and machine serial number before ordering
• Check spline specification, mounting dimension, and control type
• Request strict pressure and performance testing before shipment
• Shockproof wooden packaging to prevent transit damage
• Quality warranty covering manufacturing defects
