100% Compatible AP2D28 Double Tube Pilot Pump For Mining Work

Pilot Pump Introduction

The AP2D28 dual-port pilot pump is a gear-type auxiliary pump primarily used in the hydraulic systems of mini excavators. It works in conjunction with the main piston pump to provide a stable low-pressure pilot control circuit. Featuring a dual-port design, it is compact, reliable, and originally part of the Uchida/Rexroth series. Now, it is mostly produced as a high-quality compatible component and is widely used in 5-8 ton excavators, such as the DH55/DH60, R55/R60, EC55/EC60, and EX60 models. It is a common core component in the hydraulic systems of mini excavators.

This series covers the essential needs of hydraulic pilot control with practical, field-proven solutions. It offers a balanced combination of size, performance, and serviceability that suits both new machine designs and replacement applications in existing fleets.
