Pentair WhisperFlo Pool Motors

Swimming Pool Motors

When selecting a replacement motor, start with the frame type, then select the HP of the pump. Often there are two motors that match the first two criteria. They are often referred to as full rated, up rated or max rated to determine the correct replacement match the service factor (SF) which is on the motor label. ?It is important to remember the motor being replaced must equal or exceed the HP x Service factor of the original motor. If the SF cannot be determined from the label, often the impeller will help us determine what the correct model is. ?A larger motor will not necessarily cause problems, but a smaller motor can overheat and cause premature failure of the motor.
When replacing a motor you must replace the seals, o-rings and gaskets. Most motors fail due to seal failure, not replacing the seal is only looking for problems.
