This is the SNTech impower Marathon 1.25 Horsepower Variable Speed Pool Motor RB003. There's more to the imPower pool pump motor than just energy efficiency. It's lighter and more compact than typical induction motors and operates with less noise, offering virtually silent filtering operation. Also, the imPower features TEFC (Totally Enclosed Fan Cooled) construction and a high-strength bearing system. What does all that mean? Simply that this motor is as tough and reliable as it is smart.
The imPower motor is also built on the ECM technology that we have manufactured for the HVAC market for over 20 years, ensuring that the benefits of the imPower motor can be experienced for many years.
imPower's three-speed design makes it ideal for pumping applications. As the affinity law of hydraulics states, if the speed of the motor is halved, the power is reduced by a factor of eight. The lower speeds with the imPower motor enable the pump to filter at lower speeds, resulting in energy savings for the homeowner.
The imPower motor is inherently more efficient than traditional induction motors, thanks to its innovative brushless permanent-magnet design. As compared to a single speed induction motor, the imPower motor is over 12% more efficient on high speed, over 50% more efficient on medium speed, and over 80% more efficient on low speed. All in all, a great pool pump motor indeed.
