Xylem (ITT Laing Thermotech) E-10 circulation pump - Rotor Assembly

Xylem (formerly ITT Laing) E-10 rotor assembly - suits E-10 circulation pumps with plastic 'finger style' bases only

Does not suit E-10 pumps with metal base plates or any version of SM9xx series pumps 

Xylem E-10 rotor assembly includes the impeller, magnetic section and carbon bearing - this is a one piece unit that cannot be dismantled further.
This rotor assembly will be required when the E-10 pump fails due to dry running or chemical etching/failure of the carbon bearing. Symptoms of this are pump stalling, grinding, or rattling whilst running.
The bearing surface is water cooled and lubricated - failure to ensure correct chemical balance and levels, or water presence results in this failure.

Ensure the ceramic ball on the motor is in perfect condition and there seems to be signs of life/attempted rotation before considering replacing this impeller - otherwise complete pump replacement is required.
