All of the new pumps are variable speed pumps which are mandated by the Arizona state. Traditional pumps operate at set, unchangeable speed. Those speeds are almost always higher than required. As a result, they overpower the jobs they’re assigned to do, which waste energy.
The variable speed pump allows custom programming of optimum pump speeds for specific task such as filtering, heating, cleaning, spa jets and water features. For virtually all applications, the optimum speed is lower than the preset, unchangeable speeds of older pumps. Thus they can cut energy consumption up to 87% over traditional pumps.
