Daily visual inspection​ for external leaks, cracks, or damage.

Check hydraulic oil level​ in the main tank before each shift.

Monitor hydraulic oil temperature​ during operation.

Inspect oil condition​ for contamination, discoloration, or aeration.

Check pump drive belt​ for tension, cracks, and wear.

Listen for unusual noises​ from the pump (cavitation, whining).

Verify pump mounting bolts​ are tight and secure.

Inspect all hydraulic hose connections​ at the pump for leaks.

Check inlet (suction) line​ for restrictions, kinks, or air leaks.

Ensure the oil reservoir breather cap​ is clean and unclogged.

Monitor system pressure​ using gauges for abnormal readings.

Check for excessive case drain flow​ which indicates internal wear.

Inspect the pump shaft seal​ for any signs of oil leakage.

Keep the pump and surrounding area clean​ from dirt and debris.

Follow recommended oil change intervals​ using specified XCMG-grade oil.

Change hydraulic filters​ (suction, pressure, return) as scheduled.

Bleed air from the hydraulic system​ after servicing or oil changes.

Use a laser thermometer​ to check for abnormal pump housing temperature.

Verify proper operation of the main system relief valve.

Check for damaged or vibrating hydraulic lines​ near the pump.

Ensure the oil cooler is functioning​ to maintain optimal oil temperature.

Inspect the pump servo control linkage​ (if equipped) for smooth operation.

Record pump operation hours​ for preventive maintenance scheduling.

Avoid running the pump at full stroke/load​ for extended periods unnecessarily.

Use proper filtration units​ when adding new hydraulic oil.

Check the alignment of the pump drive coupling.

Inspect the condition of the pump's external control levers or solenoids.

Follow XCMG's specific warm-up procedure​ in cold weather before full operation.

Immediately investigate any sudden loss of power or slow operation.

Consult the official XCMG 245 service manual​ for all detailed procedures and specifications.

Product Description

Key Functions of Hydraulic Pumps in Mini Excavators

Powering Movement: The primary function of hydraulic pumps in mini excavators is to provide the necessary power to move the machine’s components. When the operator activates a control, the hydraulic pump sends pressurized fluid to the corresponding actuator, allowing for smooth and precise movements.

What is a Hydraulic Pump?

A hydraulic pump is a mechanical device that converts mechanical energy into hydraulic energy by moving fluid through the hydraulic system. In mini excavators, hydraulic pumps are responsible for generating the hydraulic pressure needed to operate various attachments and functions, such as the boom, arm, bucket, and swing mechanisms.

Hydraulic pumps are vital components of hydraulic systems, providing the necessary power to perform a wide range of tasks across various industries. Understanding the different types of hydraulic pumps and their applications can help you choose the right pump for your specific needs. Whether you are in construction, manufacturing, or any other field that relies on hydraulic systems, knowing how hydraulic pumps work will enhance your ability to maintain and optimize these essential machines.
