This gear pump is a critical component of the hydraulic system, responsible for generating the necessary flow and pressure for excavator functions. Manufactured to precise tolerances, it offers reliable performance and durability, outperforming worn pumps that exhibit reduced flow or internal leakage. Operators may experience sluggish hydraulic response, loss of power, or unusual noises from the pump when this unit fails.

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 failing gear pump may first present as a noticeable decrease in hydraulic system speed and power. If left unaddressed, the pump can overheat, leading to internal damage and potential contamination of the entire hydraulic system. The worst consequence is a complete loss of hydraulic function, rendering the excavator inoperable.
Ensure the hydraulic system is completely drained and flushed before installing the new pump to prevent contamination. Never run the new pump dry; prime it with clean hydraulic fluid before initial startup.
Replace the hydraulic filter and inspect the hydraulic fluid for signs of contamination or wear metals before installing the new pump.
