Product Description

The AP2D25 hydraulic main pump is a dual-plunger pump specifically designed for modern 55/60-ton excavators. It features an integrated structure of the main pump and the pilot gear pump, equipped with an electromagnetic flow control valve, perfectly matching the hydraulic system of modern R55-7 and R60-7 complete sets. The power output is strong and stable, the compound actions are smooth, effectively improving problems such as slow equipment operation, insufficient digging force, pressure loss during descent, and vehicle stalling.

1. Original size dimensions, oil ports, and installation holes are exactly the same as those of the original assembly, allowing for direct installation and replacement without modifying the piping.
2. The cylinder body, plunger, and flow distributor plate are made of high wear-resistant alloy steel, resistant to high temperatures and impact. They are less prone to wear during long-term continuous operation and have a longer service life.
3. The electromagnetic variable responds quickly, the flow adjustment is smooth, the digging is powerful and the control is gentle, the operation efficiency is higher, and the fuel consumption is more economical.
4. The entire machine is spray-painted and baked, rust-proof and corrosion-resistant. Each assembly is factory-tested with hydraulic test benches for pressure, ensuring stable performance and a low rework rate.
