Gear Pilot Pump K7V63 For SK130-8 SK135 Medium Sized Tracked Excavator
Gear Pilot Pump K7V63 For SK130-8 SK135 Medium-sized Tracked Excavator
Pilot Pump Introduction
The K7V63 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 medium-sized excavators (usually equipped with K7V63DTP 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 13-14 ton crawler excavators such as Kobelco SK130-8/9, SK135, SK140-8/9, and Case CX130, 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.
