The pump runs but the motor protection trips

WARNING:

Always disconnect and lock out power before servicing to prevent unexpected startup.
Failure to do so could result in death or serious injury.

NOTICE:

Do NOT override the motor protection repeatedly if it has tripped. Doing so may result in
equipment damage.

Cause

Remedy

The motor protection is set too low.

Set the motor protection according to the data plate and if applicable the

cable chart.

The impeller is difficult to rotate by

hand.

• Clean the impeller.
• Clean out the sump.
• Check that the impeller is properly trimmed.

The drive unit is not receiving full

voltage on all three phases.

• Check the fuses. Replace fuses that have tripped.
• If the fuses are intact, notify a certified electrician.

The phase currents vary, or they are

too high.

Contact the local Xylem service shop.

The insulation between the phases

and ground in the stator is

defective.

1. Use an insulation tester. With a 1000 V DC megger, check that the

insulation between the phases and between any phase and ground is
> 5 megohms.

2. If the insulation is less:

Contact the local Xylem service shop.

The density of the pumped fluid is

too high.

Make sure that the maximum density is 1100 kg/m

3

 (9.2 lb/US gal)

• Change the impeller, or
• Change to a more suitable pump.
• Contact the local Xylem service shop.

There is a malfunction in the

overload protection.

Replace the overload protection.

If the problem persists, refer to the Flygt Service Guide on the web or contact the local
Xylem service shop. Always state the serial number of your pump when you contact Xylem,

The pump delivers too little or no water

WARNING:

Always disconnect and lock out power before servicing to prevent unexpected startup.
Failure to do so could result in death or serious injury.
