Product details

The Pentair WhisperFlo WFK-8 is a 2 HP full rated pool pump wired for three phase power. It is a single speed pump with 2 in. ports, finished in almond, and it carries Pentair part number 011643.

Three phase, not residential

The key detail on this model is the motor. Three phase power is a commercial service. If the equipment pad is fed from a normal residential single phase panel, this is not the right pump. Check the panel and the existing motor nameplate before ordering.

Full rated horsepower

Full rated means the pump makes its 2 HP without leaning on the service factor. Two pumps can both say 2 HP on the label and move very different amounts of water depending on how that horsepower is rated, so match the rating as well as the number when replacing a pump.

Part numbers and voltage

This pump appears under two numbers, 011570 and 011643, with 011643 carried here. The voltage is listed both as 208/230/460V and as 230/460V. Confirm both against the nameplate on the pump you are replacing, or against your specification, before the pump is wired in.

Questions and answers

What people ask about this product, answered by our pool techs.

Will this run on my home power?
Unlikely. It is a three phase pump. Standard residential service is single phase, so this pump suits commercial or light commercial installations with three phase power available.
What does full rated mean?
A full rated pump produces its stated horsepower on its own, without counting the service factor. An up rated pump of the same nameplate horsepower moves less water.
Which part number is correct, 011570 or 011643?
Both appear on this pump. The number carried on this listing is 011643, and 011570 is shown alongside it. Check the number in your specification or on the old pump label before ordering.
What voltage is it?
It is listed as 208/230/460V and also as 230/460V. Both readings appear in the source material, so confirm the nameplate against your service before wiring.
