Which Replacement Motor Do I Need?
The best way to determine the proper replacement motor is by having the pump manufacturer's name and model number. By “pump”, we mean the complete unit which is comprised of the wet end (where the strainer basket is) and the motor. Regardless of the pump you have – Hayward, Pentair, Sta-Rite, Jandy, etc. - the motor is made by a third party manufacturer and the same motor is used on multiple pumps. There is no such thing as an A.O. Smith or Magnetek pump – these companies only make the pool pump motors. Since replacement pool pump motors are listed according to the complete pump model, having only the model number from the motor makes it much more difficult to cross-reference. Look instead for a label or plate on the basket portion of the pump and see if you can get the model number for the whole unit, such as “Hayward Super Pump SP2605X7”. With this information, it is usually fairly simple to look up the proper replacement. If you cannot locate the pump model name or number, check for a part number on the strainer basket lid. This will usually be molded into the plastic and can often be used as a cross-reference to figure out which pump you have.
