Product Description

Gear Pilot Pump PVD‑1B‑23 For Hitachi ZAX70 Small‑sized Tracked Excavator

Pilot Pump Introduction

The PVD‑1B‑23 pilot pump, a gear‑type auxiliary hydraulic pump manufactured by Precision Machinery, is primarily used to provide stable low‑pressure pilot control oil pressure for the main hydraulic system of small‑sized excavators (usually equipped with PVD‑1B‑23 series axial piston main pumps). This ensures precise response of control components such as operating handles and valve groups, enabling smooth start‑up, switching, and proportional control of excavator movements. It also avoids the main pump directly bearing high‑frequency control loads, thereby improving system reliability, response speed, and overall operating comfort. It is widely used in 6‑8 ton crawler excavators such as Hitachi ZAX70, ZAX60, and is typically installed at the rear or side of the main pump, supporting earthmoving, construction, and other engineering scenarios.

This pilot pump series contributes to overall machine safety by providing stable and controlled pressure signals. Consistent output helps prevent sudden or erratic movements that could affect operational safety.

As an experienced hydraulic manufacturer, Hebei Runhe operates with 12+ years of expertise. It supplies hydraulic cylinders, pumps and motors to agriculture, lifting and engineering sectors. It provides non‑standard customization and follows diversified development and lean management.
