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.

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.

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.

I'm trying to find a replacement motor for my pool pump but my model number doesn't match what you have listed as the model number. My model number begins with a C48 and yours begins with an SP. Please help.

A  Answered on 1/18/2012 by InyoPools Product Specialist Patrick P.

What we have listed on our chart pages is the pump model number. The model number you have will just identify the motor. If you look on the plastic housing on the pump there should be a sticker which will have the pump model number. You can usually find this by the discharge port on the pump. Once you locate it you can choose the correct replacement motor. Be certain to change the shaft seal and gaskets as needed. You can use our >How to guide if you need help.

Does this motor come with a cord? If not, do you supply the correct cord?

A  Answered on 8/6/2012 by InyoPools Product Specialist Patrick P.

The Magnatek BN25 does not come with a cord. For a 115 volt application, if you need a twist lock cord, you can find it here: http://www.inyopools.com/Products/07501352011327.htm or a standard 3 prong cord here: http://www.inyopools.com/Products/07501352015032.htm

GFCI was tripping, Motor burned up.

Written on 8/21/2019 by Guest

I closed the valves, disconnected motor and impeller assembly from filter (one union connection), propped filter on angle to keep water from coming out of the union connection while repair was being made. Took motor/impeller assembly inside (in the AC) and replaced motor along with seals and "O" rings, reconnected motor/impeller to filter, plugged it in and turned it on.

Written on 6/13/2018 by Guest

Called INYO pools, gave product number, motor arrived in two days, unscrewed the bolts, pulled out the older motor, attached the power cord, reattached the impeller, screwed it into place, turned it on. All good to go!
