A  Answered on 11/6/2018 by InyoPools Product Specialist Lennox H.

Hi, Joseph. he Century B2852 motor is the correct replacement, however, you can also use this UQC1072 as an energy efficient replacement.

Is this the correct replacement motor for a sta rite max e glass 2 motor ?

A  Answered on 5/8/2018 by InyoPools Product Specialist Hector F.

Those pumps can sue multiple motor models so you would need to know the specific motor model, part or catalog number. If that is not present then you may need to locate the impeller part number which is usually molded onto the plastic of the impeller itself.

i'm looking to replace my magnetek centurion part #168451, will this motor be an acceptable replacement? Also what would be the difference or advantage of this motor vs the usq1072?

A  Answered on 6/17/2016 by InyoPools Product Specialist Scott W.

All three of those motors have the same total horsepower, the difference is going to be the amount of amps being used. The energy efficient motor is going to use about 25-30% less amps while putting out the same amount of horsepower.

does this work on Hayward super pump?

A  Answered on 8/28/2015 by InyoPools Product Specialist Matt S.

The UQC1072 is not compatible with the Hayward Super Pump as this motor is a square flange, and the Super Pump uses a round flange motor. The round flange equivalent to the UQC1072 is the UCT1072 A.O. Smith 3/4 HP Energy Efficient Motor

Why should I purchase a Tune Up Kit?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.

Why do I need to purchase a new shaft seal?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.

What is Service Factor?

A  Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.
