Certikin Imbalance or Misalignment

Pump vibrates excessively, causing pipework to shake and noise to transmit through the plant room.

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 partially blocked impeller, misaligned motor and wet end, missing or perished anti‑vibration mounts, loose pump mounting bolts

Safety: Isolate power before tightening or adjusting the pump.

Check mounting: Ensure the Certikin pump is securely bolted to a solid base and that any rubber anti‑vibration feet are intact.
Inspect impeller: Remove the wet end and check the impeller for broken vanes or debris causing imbalance. Replace if damaged.
Align motor and housing: When refitting the motor, tighten bolts evenly to avoid twisting the housing.
Support pipework: Add supports to long pipe runs to reduce transmitted vibration.
