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.

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.

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.

How many gallons per minute does this model move?

Hello Stu - The SN1072 is used on a 3/4HP full rated Northstar Pump. The GPM of a pump is determined by the "total dynamic head" or TDH . Example: At 40' of TDH, the 3/4HP full rated Northstar pump would push 80 GPM.

Bought two motors, as the first turned out to be defective, would not start; highly unusual. The second motor worked fine. Replacing the motor, seals and gasket required complete disassembly and reassembly of the pump. the process involved disconnecting power, removal of the plate attached to the motor , removal of the non rotating seal in its housing , the rotating seal on the motor shaft and the impeller from the shaft. Replacing the parts and re assembling is straight forward, except that the run capacitor on the motor must be removed to allow locking the motor shaft rotation to assemble the impeller on the shaft. Replacing the finished assembly to the pump is fairly easy, except that if becomes difficult to mate to the body of the pump, because the gasket makes for a tight fit. Use a lot of approved gasket lubricant to all mating surfaces to help the process. Everything takes two or more hours to complete, except that I had to do it twice, due to the defective first motor.
Filing a warranty claim for the bad motor if fairly easy through INYO, except that it seems to take forever to get a resolution. Still waiting for some kind of answer after more than two weeks.

(5 out of 5 stars) Excellent Pump Moter Replacement
Reviewed By: PoJo from Clarence, NY ()
Pros: Awesome fit - excellent replacement
Cons: none
Tip to get the impeller off the old pump moter: use a 7/16" open ended wrench - it slides in near the capacitor on the electrical side... rotate the impeller until the wrench slides into place at the end of the shaft and then one person holds the motor and the wrench while a 2nd person loosens the impeller off with bare hands by turning the impeller counter clock-wise.

Pros: Does what it needs to do.
This motor was exactly what I needed for my pool, and much cheaper than what I could purchase locally. The first one I ordered broke down after a few months, so I am hoping this one is more reliable. So far so good. Also, INYO sent me this new motor at no additional charge.
