What is Service Factor?
Reply
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?
Reply
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?
Reply
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.

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

How can I tell whether or not my motor is a dual or single speed?
Reply
Most dual speed motors will have a toggle switch that will allow you to adjust the motor speed to either high or low. Another way to tell if your motor is dual speed is by looking at the RPM's on the motor specifications label. If there are two RPM's listed such as: 1725/3450 then motor is dual speed. If there is only one RPM, then motor is single speed.

(5 out of 5 stars) 2 HP Dual Spd Motor - Full Rate B984
Reviewed By: David P. from chicago, IL ()
Pros: exact fit, good as original
Cons: A little pricey but better than buying a new pump
This was a replacement pump motor of the OEM pump motor for my Jandy 2 speed 2HP pool pump. It was an exact fit and there was no problems replacing the OEM pump. Everything lined up properly and the pump performs as good as the original in both low and high speed. Please contact or Inyo pools tech support as they will help ensure that you find the exact part you need

(5 out of 5 stars) Great motor
Reviewed By: Matte from Los Angeles, CA ()
Pros: Price
Cons: none yet
Got this for a customer instead of replacing a whisper flow pump. Great price = very happy customer. They have a various pumps and heaters that will need to be replaced in the future. I'm sure we are going to get all of their future business. Found Inyo Pools online and will be sticking with them. Cheers. Matte
