Installed this motor and it appears the impeller needs a counter clockwise motor rotation. Can the motor direction be changed.


A  Answered on 11/13/2020 by InyoPools Product Specialist Hector F.

Hi Eugene, these pool motors are designed to only spin in one direction and cannot be changed.

I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

Can you direct me to the proper hi low switch for this motor?

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

Unfortunately the manufacturer does not offer the switch for the 2 speed 220v motors any longer. If you already have a 220 volt timer (on/off) you would need an Intermatic T106R to switch from high to low speed. If you do not have a timer currently you would need the T10604R which is a 220v on/off timer and a high/low timer.

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.

Can you replace single speed pump motor with dual speed pump motor?

A  Answered on 5/16/2007 by InyoPools Product Specialist Patrick P.

Yes but you can't go with a higher HP than the single speed motor. For example if you have a 1 HP single speed you cannot go with a 1.5 HP dual speed motor; you would be able to use a 1 HP dual speed motor. Customer would need to purchase a toggle switch or timer to switch from high speed to low speed.

Pump Motor Burned Out.

Written on 12/6/2018 by Guest

The repair is fairly straightforward: I followed the repair guideline video on InyoPools.com and purchased the additional parts between the pump motor and pump, and in 30 minutes the job was done.

Were these instructions helpful?
