Common Failure Modes in Hydraulic Pumps

Hydraulic pumps like the 90-L-100 series are engineered for durability, but over time, even the most robust systems may encounter issues. These include:

Overheating: Often caused by fluid contamination or incorrect viscosity levels.
Pressure drops: Indicative of internal leakage or damaged valve plates.
Noise and vibration: Typically signal misalignment, cavitation, or air ingress.
Reduced flow rate: Due to worn components or clogged filters.

By addressing these problems promptly, downtime can be minimized and pump life extended.

Troubleshooting Guidelines and Practical Tips

To support maintenance professionals and end users, BAOLILAI recommends the following diagnostic and corrective steps when performance issues are detected in your hydraulic pump system:

1. Check Fluid Quality and Levels

Use ISO 4406-rated hydraulic fluids and ensure proper fluid levels. Degradation in oil quality is one of the most frequent causes of inefficiency and internal wear.

2. Inspect Pump Alignment

Incorrect alignment during installation can lead to shaft or coupling wear. Ensure precision in mounting and shaft-to-motor connection.

3. Monitor Operating Temperatures

Excessive heat may indicate overloading or fluid bypass. Install temperature sensors to monitor working conditions and adjust accordingly.

4. Replace Worn Seals and Bearings

In long-term operations, seals and bearings degrade, causing internal leakage and decreased output. Scheduled preventive maintenance is essential.

5. Perform Pressure and Flow Testing

Utilize diagnostic test ports to measure real-time pressure and flow rates. This helps identify whether a drop in performance originates from the pump or downstream components.

Long-Term Maintenance Strategy

A proactive maintenance approach greatly enhances the performance and service life of your BAOLILAI hydraulic pump. We advise establishing:

Routine inspection intervals (weekly/monthly/quarterly)
Record-keeping for fluid changes, pressures, and maintenance actions
Using genuine BAOLILAI replacement parts to preserve system integrity

Through these practices, many of our clients report 30–40% fewer breakdowns and up to 25% longer service life on comparable systems.
