This hydraulic gear pump is responsible for generating the high-pressure flow required for the excavator's primary hydraulic functions, such as boom, stick, and bucket actuation. Manufactured with precision-machined gears and a robust housing, it ensures reliable performance and longevity, unlike a worn pump that exhibits reduced flow and pressure. Operators will typically observe sluggish or unresponsive hydraulic movements, such as a slow-moving boom or bucket, when this pump begins to fail.

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.
The initial symptom of a failing gear pump is a noticeable decrease in hydraulic system pressure and flow, leading to slower machine functions. If left unaddressed, this can progress to intermittent loss of hydraulic power and potential overheating of the hydraulic oil. The ultimate consequence is the inability to perform critical work tasks, leading to costly downtime.
Ensure the hydraulic system is completely drained and clean before installing the new pump to prevent contamination. Always prime the new pump with clean hydraulic fluid before initial startup to avoid dry running.
Replace the hydraulic filter element and inspect the hydraulic fluid for signs of contamination or degradation when replacing the gear pump.
