Product details

The Pentair WhisperFlo WFK-12 is a 3 HP full rated pool pump built for three phase power at 208/230/460V, plumbed in 2 inch.

Full rated, three phase

Full rated means the pump makes its stated horsepower without leaning on the service factor, so it moves noticeably more water than an up rated pump wearing the same number. Three phase is the supply found in commercial equipment rooms, and this pump will not run on a single phase feed.

The hydraulics

The WhisperFlo design moves water more efficiently and more quietly than competing pumps of the same size. On a pump running long hours, that difference shows up on the power bill and in the plant room noise level.

Part numbers

This pump is carried under 011644 and also appears as 011571. If you are matching a pump already installed, read the number off the pump label before ordering.

Questions and answers

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

Is this a three phase pump?
Yes. It is wired for three phase power at 208/230/460V, so it will not run on a single phase supply.
What does full rated mean?
A full rated pump delivers its stated horsepower without relying on the service factor. An up rated pump of the same nameplate horsepower moves less water.
Which part number is right, 011644 or 011571?
Both appear against this pump. 011644 is the manufacturer part number on the listing and 011571 is carried alongside it, so confirm against the pump label if you are matching an existing installation.
What size plumbing does it take?
2 inch suction and discharge.
