This pilot pump adopts external‑meshing precision gear structure with precise grinding and strict clearance matching, ensuring low internal leakage and high volumetric efficiency. It is designed for direct integration with K3V180 axial piston main pump, supplying stable pilot pressure for control system, regulator and servo mechanism. The housing and gears are made of high‑strength alloy material with heat treatment, featuring good rigidity, wear resistance and shock resistance. Standard mounting interface and shaft specification enable direct replacement, stable operation under high temperature, vibration and heavy‑load conditions, effectively improving the response speed and control stability of the whole hydraulic system.
Precision grinding gear structure ensures stable oil output, low pulsation and low noise.
High‑strength alloy material with heat treatment provides excellent wear resistance and long service life.
Compact integrated design saves installation space and adapts to limited cabin layout.
Low internal leakage and high volumetric efficiency improve overall energy utilization.
Standard shaft and mounting dimensions enable high interchangeability and easy replacement.
Strong anti‑vibration and high temperature resistance, suitable for harsh construction site environments.
