Why is my Sulzer Water Pump making excessive noise or vibration?
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.
What to do if my Sulzer Water Pump has low head or flow?
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?
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.
What to do if the impeller is jammed in my Sulzer Water Pump?
If the impeller of your Sulzer Water Pump is jammed, you should inspect and remove any object causing the jam. Additionally, check the gap between the impeller and the bottom plate, adjusting it if necessary.
What to do if the gate valve is closed or the non-return valve is blocked in my Sulzer Water Pump?
If you find that the gate valve of your Sulzer Water Pump is closed or the non-return valve is blocked, open the gate valve and clean any blockage from the non-return valve.
What to do if there is level control override in my Sulzer Water Pump?
If there is a level control override in your Sulzer Water Pump, check for a float switch that is faulty or tangled and held in the OFF position in the sump.
