Hydraulic pump CBGJ2063 2040 4120000866 17097838

Product Introduction

This CBGJ2063/2040 tandem hydraulic gear pump (part number 4120000866, 17097838) is a dual-section gear pump widely used on wheel loaders. It supplies pressurized hydraulic oil separately for working system and steering system. The two integrated pump sections deliver independent flow to realize bucket lifting, arm movement and steering operation simultaneously, supporting continuous heavy-duty work in mining and earthmoving sites.

The pump housing adopts high-strength cast iron. The internal driving and driven gears are made of alloy steel with carburizing and quenching treatment, featuring high hardness and strong wear resistance. Precision machining of gear pairs reduces internal leakage and noise while maintaining stable volumetric efficiency under high pressure. The spline drive shaft is heat-treated to withstand large torque impact. The inlet and outlet flange mounting holes strictly follow OEM specifications for easy installation and pipeline connection. The surface anti-rust coating protects the pump body against mud, water splash and corrosion in harsh outdoor environments.

Manufactured strictly in accordance with OEM dimensional standards, this hydraulic gear pump can directly replace original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every finished pump undergoes pressure test and flow inspection before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
