Compact Structure Excavator Pilot Pump K3V112 For R210 DH215 SK200 EC210

Pilot Pump Introduction

The pilot pump K3V112 is a gear-type pilot pump that complements the K3V series swash-plate axial piston variable main pump. It is typically installed at the rear end of the main pump in a tandem configuration, with a 13-tooth input spline.The pump features a compact structure, low noise, and high resistance to pressure shocks. Its primary function is to provide a stable pilot control oil source for the hydraulic system, supporting the main pump's variable displacement regulation, power regulation, pilot operation of control valves, and system oil replenishment.This ensures precise flow and pressure response, smooth and reliable operation under complex working conditions in excavators, while improving overall efficiency and service life.

The pilot pump series supports machine builders who need dependable control components without excessive complexity. It delivers the necessary pilot pressure and flow characteristics required for safe and efficient operation of today’s hydraulic systems.
