Product Descriptio

Compatible with Hitachi EX70-6 hydraulic main pump, featuring the Rexroth AP2D361 pump core structure. The entire machine adopts the same original variable displacement piston pump structure, integrating the main pump and pilot pump. Wear-resistant parts are optimized for high-frequency heavy-duty operations on small excavators. The cast pump body resists impact from construction site gravel and high-temperature hydraulic oil corrosion, ensuring durability and stability under long-term heavy-duty conditions in earthmoving, crushing, and landscaping construction. It is a core replacement part for Hitachi 7-ton excavators.

1. The high-precision distribution plate and wear-resistant piston pair combination ensure stable output oil pressure, smooth and uninterrupted lifting, slewing, and traveling actions, effectively solving common problems such as weak equipment movement, stalling, high oil temperature, and internal oil leakage.

2. The pistons and cylinder are made of high-strength alloy material, significantly reducing internal wear caused by long-term crushing and earthmoving operations, minimizing frequent maintenance downtime costs.

3. Precise flow and pressure ratio restores the original factory power after installation, providing powerful boom lifting, stable traveling, and sufficient impact force from the breaker. Standard original installation points, saving time and effort for mechanical repair and disassembly, no need to modify any pipelines, complete with all the sealing parts, ready for direct assembly upon arrival.
