Alternative Numbers: 20/902900, 400/E0868
Type: Tandem (dual-section) hydraulic gear pump
The 36/26 ccr hydraulic pump is a core component of the hydraulic system in JCB 3CX and 4CX backhoe loaders. It is the heart of the hydraulic system, responsible for generating oil flow and pressure to power all working functions such as the boom, bucket, loader arms, auxiliary hydraulics, and attachments.
Its precision gear design and high-strength materials ensure factory-level performance, full hydraulic power, and fast, smooth operation even under heavy-duty working conditions.
The pump features two independent working sections with a shared suction port, allowing stable and simultaneous operation of multiple hydraulic circuits.
Technical Specifications
