KOMATSU Bulldozer Hydraulic Pump 708-1S-00290
This is a variable displacement piston pump, typically designed as a slant disc, that can automatically adjust displacement and output flow according to system requirements, with high efficiency and power density.
This hydraulic pump is one of the core hydraulic power sources for the Komatsu D series medium-sized bulldozers. It is mainly suitable for the following classic models:
· KOMATSU D65EX/PX-12
· KOMATSU D65EX/PX-12EO
· KOMATSU D85EX/PX-12EO
· KOMATSU D85EX/PX-12SE
(Note: EX represents the extended track type, PX represents the standard track type, EO represents compliance with specific emission standards, and SE may represent special configurations.). This pump is a universal core component for these models. )
This hydraulic pump is the "heart" of the entire bulldozer hydraulic system. Its main functions are:
1. Generate high-pressure hydraulic oil: convert the mechanical energy transmitted by the engine into hydraulic energy.
2. Provide power for all hydraulic actions: Its output is driven by high-pressure oil:
·Working equipment: lifting and lowering shovel (bulldozer shovel), tilting shovel.
·Steering system: controls the left and right steering of the bulldozer.
·Provide power to other auxiliary systems (in some designs).
If this pump malfunctions, the main functions of the entire equipment will be basically paralyzed.
