  If the ITT Water Pump fails to convey, several issues could be the cause. First, ensure that valves in the delivery or inlet line are fully open. Check for any blockages or encrustations in the delivery/inlet line, pump, or filter, and clean them if necessary. Also, verify that the pump is completely filled. Make sure the pump's speed isn't too low, and increase it with a speed regulator if needed. Another potential issue could be an outlet line blockage, which would require cleaning. Finally, check if connecting screws are properly tightened and tighten if needed.

  ITT Water Pump may fail to convey due to several reasons. Excessive play between the feed screws or between the feed screws and casing could be a cause, requiring repair or exchange of worn parts. Incorrect pump direction of rotation could also be the reason, so you should check and adjust the drive's direction of rotation if necessary. The issue could also be related to the conveying medium: if the viscosity or temperature deviates from the pump's design data, it may cause the pump to fail. Also, check if the cross section of the inlet or outlet line is too narrow.

  If the ITT Water Pump fails to convey because the speed is too low, increase the speed using the speed regulator.
