Hurlcon Imbalance / Misalignment

Pump vibrates excessively, causing pipes to shake or rattle.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Damaged or unbalanced impeller, Loose mounting bolts on Hurlcon pump base, Misaligned pipework putting stress on pump, Worn motor bearings

Safety: Turn off pump before tightening bolts or touching pipework.

Check mounting: Ensure the Hurlcon pump is firmly bolted to a solid base and that rubber feet (if fitted) are intact.
Support pipework: Add pipe supports to reduce stress on the pump unions.
Inspect impeller and bearings: If vibration persists, inspect the impeller for damage and check for bearing noise.

Severe vibration can damage plumbing and should be corrected promptly, often requiring impeller or motor service.
