Product details
The Century B668 is the replacement motor for the Pentair Letro booster pump, rated .75 HP and wired for 115 or 230 volts. It covers booster pumps built after 3/97.
Check the date first
Letro booster pumps changed at March 1997, and the motor changed with them. A pump made before that date takes a different motor, so read the build date off the pump label before you order rather than going by the model name alone.
Motor only
This is the motor, not a complete booster pump. When the wet end is still sound and the failure is electrical, replacing the motor is the normal repair and it puts the pressure back behind the cleaner. The same motor is cross referenced as 3285-81 on older paperwork.
