Pentair specifications Why slower is better, IntelliFlo VS+SVRS 654

Two key technology innovations drive significant energy savings

IntelliFlo VS+SVRS pump includes exclusive, breakthrough motor technology and controllable, variable-speed technology that combine to drive down energy use and cost. And the savings potential may be measured in thousands of dollars over its long life.

First, the IntelliFlo VS+SVRS pump uses an exclusive permanent magnet motor—like those used in hybrid cars—in place of a traditional induction motor. Permanent magnet motors are fundamentally more energy efficient.

Second, the IntelliFlo VS+SVRS pump includes a variable speed capability, along with digital controls and proprietary software that allow custom programming of optimum pump speeds for specific tasks—filtering, heating, cleaning, spa jets, etc.

Here’s just one comparative example:

Traditional pumps’ one pre-set speed are almost always greater than that needed to meet the health department turnover requirements.

With a variable speed pump, the optimum speed will almost always be lower than the pre-set, unchangeable speeds of older pumps. IntelliFlo VS+SVRS pump’s eight settable, changeable speeds (ranging from 1100 to 3450 RPMs) mean you can program the exact flow requirements for each task, assuring the lowest energy use possible…adding to your savings. Plus with IntelliFlo VS+SVRS pump, you may be able to further reduce energy costs by reducing flow rates during non-pool use hours while maintaining 24 hour-a-day filtration…at a much lower cost. Check with your local health department for requirements in your area.

Pump	Annual Kilowatts Use	Annual Electric Cost	Savings Difference*
	@ 24 hr/day Run Time	@.15 Kwh
2 HP	19,272	$2,891
IntelliFlo VS+SVRS	9,654	$1,448	$1,443 or 50%

*Actual savings can vary. Example reflects savings for an average 30,000 gallon commercial pool operating 24 hours per day at a flow rate sufficient to perform a minimum 6 hour turnover.

Pump Motor Speed vs. Power Consumption

Why slower is better

The surprising secret to minimizing pump energy costs is to operate at the lowest speed needed to accomplish a job. It takes far less energy to move water slowly than quickly. Why? Because there’s lower resistance in the filter, accessories and plumbing system. Even with only modest pump speed reductions, the effect on electricity usage can be dramatic. In fact, reducing pump motor speed by 25% actually reduces the power needed by 58% of what’s consumed at the higher speed. A good analogy is your car: you get much better gas mileage at 30 mph than at 90 mph. The same is true with pool pumps—run slower to reduce energy used.
