This is a pump element assembly, consisting of plungers and barrels, which forms the core of a hydraulic pump, generating fluid flow. Manufactured to precise tolerances, it ensures efficient operation and longevity, unlike worn components that lead to reduced hydraulic performance. Operators may observe a loss of hydraulic power, slow implement speeds, or system overheating.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A worn pump element will first manifest as a gradual decrease in overall hydraulic system performance, such as slower boom, stick, or bucket movements. If left unaddressed, this can progress to the inability to perform heavy lifting tasks or maintain hydraulic pressure under load. This significantly impacts productivity and can lead to increased cycle times.
Thoroughly clean the inside of the hydraulic pump housing and all associated passages before installing the new element. Ensure the plungers are correctly oriented and lubricated with clean hydraulic oil during assembly to prevent initial scoring.
When replacing pump elements, it is critical to inspect and clean the hydraulic pump housing, replace the hydraulic filter, and check for any debris in the hydraulic system.
