Why is my Sulzer Water Pump switching on and off intermittently?
Your Sulzer Water Pump might be intermittently switching on and off due to several reasons: * The temperature sensor could be shutting down the pump. The motor will restart automatically once the pump cools down. * There may be an impeller blockage, so check the impeller. * Check thermal relay settings in the control panel.
What to do if my Sulzer Water Pump does not operate?
If your Sulzer Water Pump isn't operating, here are a few potential causes and solutions: * **Leakage sensor shutdown:** Check for a loose or damaged oil plug, or locate and replace a faulty mechanical seal or damaged o-rings. * **Air lock in volute:** Shake or raise and lower the pump repeatedly until air bubbles no longer appear at the surface. * **Level control override:** Check for a float switch that is faulty or tangled and held in the OFF position in the sump. * **Impeller jammed:** Inspect and remove any jammed objects. Check the gap between the impeller and the bottom plate, and adjust if necessary. * **Gate valve closed or non-return valve blocked:** Open the gate valve and clean any blockage from the non-return valve.
Why does my Sulzer Water Pump have excessive noise or vibration?
Excessive noise or vibration in your Sulzer Water Pump could be due to: * A defective bearing, which would require replacement. * A clogged impeller. Remove and clean the hydraulics. * The wrong direction of rotation. Change the rotation by interchanging two phases of the power supply cable.
How to fix low head or flow in my Sulzer Water Pump?
If you're experiencing low head or flow with your Sulzer Water Pump, consider these potential solutions: * **Wrong direction of rotation:** Change the rotation by interchanging two phases of the power supply cable. * **Gap too wide between impeller and bottom plate:** Reduce the gap. * **Gate valve partially open:** Open the valve fully.
