100% Compatible AP2D25 Double Tube Pilot Pump For Construction Machinery
Pilot Pump Introduction
The AP2D25 dual-line pilot pump is primarily used as an auxiliary pump (replenishing/pilot pump) in 5-8 ton mini hydraulic excavators. It is compatible with brands, and is used in conjunction with the AP2D25 variable displacement piston main pump. Its dual-line design provides independent ports, ensuring the stability and redundancy of the pilot control system. Its main function is to supply low-pressure pilot oil to the handle, multi-way valve, and main pump variable displacement mechanism, while also replenishing system leaks, achieving sensitive and smooth operation. It is widely applicable to models such as DH55/DH60/DX60, R55/R60, SK55/SK60, and EC55/EC60, offering reliable performance and high durability, making it an ideal component for the maintenance and replacement of hydraulic systems in mini excavators.
This pilot pump series stands out for its excellent adaptability. Multiple models within the range offer various mounting configurations, connection standards, and installation orientations. This flexibility makes the whole series a practical choice for OEMs and aftermarket applications alike.
