What to do if my ITT Water Pump runs but the motor protection trips?
- R
  Rebekah WilsonAug 11, 2025
  If your ITT Water Pump motor protection trips, consider these potential issues: * The motor protection might be set too low. Adjust it according to the data plate and cable chart, if available. * The impeller may be difficult to rotate. Clean the impeller and the sump, and check that the impeller is properly trimmed. * The drive unit may not be receiving full voltage on all three phases. Check the fuses and replace any that have tripped. If the fuses are intact, contact a certified electrician. * There may be a malfunction in the overload protection. Replace the overload protection.

What to do if ITT Flygt 5150.350 Water Pump does not stop when a level sensor is used?
- M
  Marissa EatonAug 23, 2025
  If your ITT Water Pump doesn't stop when a level sensor is used, here are a few things to check: * The pump might be unable to empty the sump to the stop level. Ensure there are no leaks from the piping or discharge connection, the impeller isn't clogged, the non-return valves are functioning properly, and the pump has adequate capacity. For more help, contact a local ITT service shop. * There could be a malfunction in the level-sensing equipment. Clean the level regulators, check their function, check the contactor and the control circuit, and replace any defective items. * The stop level might be set too low. Raise the stop level.

Why ITT Flygt 5150.350 starts-stops-starts in rapid sequence?
- M
  Mary KramerAug 28, 2025
  If your ITT Water Pump starts, stops, and starts in rapid sequence, here are potential causes: * The pump may be starting due to back-flow, which refills the sump to the start level again. Ensure the distance between the start and stop levels isn't too small, the non-return valves work properly, and the rinser isn't too long without a non-return valve. * The self-holding function of the contactor might be malfunctioning. Check the contactor connections, the voltage in the control circuit in relation to the rated voltages on the coil, the functioning of the stop-level regulator, and whether the voltage drop in the line at the starting surge causes the contactor's self-holding malfunction.

Why my ITT Flygt 5150.350 does not start?

  If your ITT Water Pump isn't starting, there are several potential causes: * An alarm signal might have been triggered on the control panel. Ensure the impeller rotates freely, the sensor indicators don't show an alarm, and the overload protection hasn't tripped. If problems persist, contact a local ITT service shop. * The pump may not start automatically but can be started manually. Check that the start level regulator is functioning (clean or replace if needed), all connections are intact, the relay and contactor coils are intact, and the control switch (Man/Auto) makes contact in both positions. Also, check the control circuit and functions. * The installation might not be receiving voltage. Verify the main power switch is on, there's control voltage to the start equipment, the f...

Why is my ITT Flygt 5150.350 Water Pump delivering too little or no water?
- K
  Kevin MortonNov 15, 2025
  If your ITT Water Pump delivers too little or no water, consider these possible reasons: * The impeller might be rotating in the wrong direction. If it's a 3-phase pump, transpose two phase leads. If it's a 1-phase pump, contact a local ITT service shop. * One or more of the valves may be set in the wrong positions. Reset the valves, replace them if necessary, and ensure they're correctly installed according to media flow and open correctly. * The impeller might be difficult to rotate. Clean the impeller and the sump, and check that the impeller is properly trimmed. * The pipes could be obstructed. Clean them to ensure free flow. * The pipes and joints might be leaking. Find and seal the leaks. * There might be signs of wear on the impeller, pump, and casing. Replace the worn ...
