Pentair WhisperFlo Pool Pump High-performance Pool Pumps Whisper-quiet operation, Maximum circulation efficiency at the lowest operating cost. Long trouble-free life. Minimal maintenance. The Pentair WhisperFlo provides all the power your pool's circulation system requires - without the wasted energy costs incurred by noisy, less efficient pumps that can require larger motors. And because they're made by Pentair, they're backed by the best warranty in the business. The right pump should circulate all pool water at least once a day... as efficiently as possible. Greater efficiency means lower utility costs...and the key lies in the heart of the pump's design. The secret is to minimize friction and turbulence. Less friction means greater efficiency. Less turbulence means less noise.

How to determine what pump size is suitable for your pool
The chart below shows the performce curve of the Pentair WhisperFlo Energy Efficient swimming pool and spa pumps. Looking at this chart you can see the scale on the left marked "METERS OF WATER" AND FEET OF WATER" which is the total daynamic head in feet/meters of water (TDH) . The total daynamic head in feet of water is the amount of pressure resistance in the pool piping (pipe size, 90 degree turns ...) the pump has to overcome to push water through the pipe. The easiest way to calculate the TDH in a pool is to read the pressure guage (PSI) readings in a cleaned and running pool filter and multiply the PSI by 2.31.
TDH = (PSI x 2.31)
You can also add a constant factor of 10 to compensate for friction loss with piping, filter media e.t.c
| TDH = (PSI x 2.31) + 10 |
Determine the Desired Flow Rate (DFR) in Gallons Per Minute (GPM) for your pool
| Desired Flow Rate DFR = Gallons of water in pool / Turn Over Rate* x 60 |
| * Turn Over Rate for public/commercial pool = 6 hours, |
| * Turn Over Rate for residential pool = 8 to 10 hours, |
Example: Desired Flow Rate DFR = 20,000 gallons / 8 hrs x 60 = 41.67 gallons per minute (residential pool)
Now you can read the pump performance curve by following the TDH line across the chart until it crosses your GPM reading. This will give you an idea if you're operating with a proper pump size.
For example, if your TDH reading is 60 and your GPM reading is 100 you should be running a 1.5 HP pool pump as in the Pentair Pentair WhisperFlo
The flow rate in GPM
of your pool is determined by the pipe size, and this in turn determines
what pump size is suitable for your pool. The table below shows the minimum
and maximum flow rates for different sizes of Plastic (PVC)
schedule 40 pipe and Copper Type K pipe. The GPM rating
of your pump should not exceed the max (gpm) value of the suction line
