• Part 3: Actual Gear Pump's Insufficient Pressure Causes System to Fall Short of Design Performance

Fault Cause Analysis

The actual gear pump exhibits insufficient pressure, causing the system to fail to achieve the designed performance:

After eliminating the possibility of discrepancies between the pump's operating pressure and the system's designed pressure value, a detailed inspection of the gear pump is required.

1. Whether the motor power selection is too low

2. Gear pump wear:​ To address this issue, it is recommended to install a filter before the pump and ensure the filter mesh count is greater than 400 to prevent the conveying medium from containing particulate matter.

   Note: Gear pumps are not suitable for conveying media containing particles.

3. Insufficient pump system fluid supply​ (For details, please refer to Gear Pump Flow Insufficiency Fault Cause Analysis Part 1: Inlet Pipeline Supply Insufficiency)
