Why does my FLYGT 3202 Water Pump run but the motor protection trips?

The motor protection might be set too low. Adjust it according to the data plate and cable chart, if available. The impeller could be difficult to rotate; clean the impeller and the sump, and ensure the impeller is properly trimmed. The drive unit might not be receiving full voltage on all three phases; check and replace any tripped fuses, or if fuses are intact, consult a certified electrician. A malfunction in the overload protection may exist, in which case you should replace the overload protection. Also, the density of the pumped fluid may be too high. Ensure that the maximum density is 1100 kg/m3 (9.2 lb/US gal). You can also change the impeller, or change to a more suitable pump.
