Why is my Sulzer Water Pump making excessive noise or vibration?
- M
  Melissa EwingAug 5, 2025
  Excessive noise or vibration in your Sulzer Water Pump can stem from several causes. It could be due to a defective bearing, which would require bearing replacement. Another cause might be a clogged impeller; in this case, you should remove and clean the hydraulics. Also, check for the wrong direction of rotation and change it by interchanging two phases of the power supply cable.

  Kelly WheelerAug 10, 2025
  If your Sulzer Water Pump exhibits low head or flow, there are a few things to investigate. First, check for the correct direction of rotation and change it by interchanging two phases of the power supply cable if needed. Also, the gap between the impeller and bottom plate might be too wide, reduce the gap. Finally, ensure the gate valve is fully open; a partially open valve can restrict flow.

Why does my Sulzer Water Pump switch on and off intermittently?
- A
  Allison VargasAug 14, 2025
  Intermittent switching of your Sulzer Water Pump can be attributed to a few reasons. If it's due to a temperature sensor shutdown, the motor will restart automatically once the pump cools down. Also, check the thermal relay settings in the control panel. Impeller blockage can also cause this issue, so inspect for that. If none of these resolve the problem, a service inspection is required.
