Why is my Goulds Pumps Water Pump not producing the rated flow or head?
- OonewtonSep 14, 2025
If your Goulds Pumps Water Pump isn't producing the rated flow or head, several factors could be responsible. Ensure the driver is wired correctly and receiving full voltage, as the impellers might not be rotating fast enough. Also, verify the impellers are spinning counterclockwise when viewed from above and check the engagement of the motor coupling. The total pump head might be too high, so check the pipe friction losses and consider using larger discharge piping. Inspect the impellers and bowls for any obstructions in the liquid passages. Check for and remove any obstructions in the pump suction inlet, as cavitation could be occurring. Finally, the impellers might be too high, requiring a reset of the impeller adjustment.
