Our store on South Patrick Drive offers many of our most popular items but did you know that C&W Pump, Pool and Motors offers more products and services than those listed? As well as pumps, motors and boat lift motors, we sell pool heaters and salt generators, new efficient pool filters and time saving pool cleaners all at very competitive prices. So before you buy any new equipment give us a call or stop by.
We recently installed a Pentair Sta-Rite IntelliPro Variable Speed Pump at our home. Our electric bill has decreased dramatically since this installation. Our pump runs at 750 rpm’s all day with the capability to run at several different rpm speeds for various other applications. One setting allows our cleaner to function; one allows the fountain jets to function with three remaining functions for other applications all at the touch of a button. If we do not return it to the slower filter setting it automatically does it after five hours. This pump is “set it and forget it”. The slower filter setting of 750 rpm allows more water to be filtered so that small particles are removed more efficiently. Our water has never been cleaner! We also upgraded our Pentair 75 sq. ft. Clean and Clear filter to a 90 sq. ft Easy Clean D.E. filter which provides more cleaning capacity and will remove particles as small as 3 microns. This upgrade is available to most Clean and Clear Filters made by Pentair. So, less energy usage, better filtering capabilities and “set and forget”, what could be better! Customers currently using a Hayward pump can also get the benefits of a variable speed pump with the new Eco-Star pump by Hayward. This is also an energy efficient “set and forget” model. This pump gives the added benefit of a removable control panel that can be attached to the wall giving you additional access. So call us to discuss the upgrade best suited for you!
Full Rated Motors vs. Uprated Motors
Service factor rating on electric motors play a large part in determining the total horsepower of a motor. Service factor is a multiplier that can help you figure if your motor is a “full rated” or “uprated” motor. For example a 1½ horsepower motor with a 1.1 service factor will perform as 1½ hp uprated motor whereas a 1 ½ full rated motor with a 1.3 service factor will perform as a 2 hp uprated motor. Some pump models use these full rated motors in application to give better performance and longer life. Most full rated motors have a start capacitor as well as a run capacitor and heavier or more windings in the motor itself. For example a Goulds GT15 has a full rated motor. This means the horsepower of the motor is 1½ but combined with the service factor of 1.3 it will perform as a 2 hp uprated motor.
The motor plate above lists the following ratings for a 3/4 HP Full-Rated Motor:
If we insert these factors into the equation, we end up with the following result

Now, suppose you really wanted to take this motor and call it a 1.0 HP motor instead. You would just INCREASE the Horsepower Rating and DECREASE the Service Factor.
VOILA . . . that 3/4 HP Full Rated Motor is now classified as a 1.0 HP Up-Rated Motor EXACT SAME MOTOR . . . DIFFERENT HORSEPOWER RATING |
We take all this into consideration when we recommend a new replacement motor for your pool or sprinkler pump. Pump impellers are matched to the horsepower of the motor. Motor horsepower can be raised but not lowered. For example a pump that came with a 1½ hp motor can be replaced with a 2 hp motor without any complication but a 1 hp motor cannot be used to replace the 1½ hp motor. THE BOTTOM LINE . . . the actual horsepower rating of a pump or motor does not really tell you much. When it comes time to replace a motor . . . you MUST consider both the horsepower and service factor. This is the only way to insure that you are getting the motor that you need. Consider also the frame size and type of the motor as well. Don’t forget to get a shaft seal and appropriate gaskets as well.
When you are replacing pump parts such as an impeller or diffuser . . . make sure you match up the exact part number or you may end up with a mismatched impeller or diffuser. As always when in doubt call us or come by.
