Product details

The Nidec ASB841A is a square flange pool and spa pump motor on the 56Y frame, open drip proof, in almond. It is listed for use with the Pentair WhisperFlo High Performance pump, models WFE-4 and WFE-26.

Ratings

It is a single speed, single phase, 60 Hz motor rated 115/208-230 V. Two horsepower figures appear against it: 1 HP, and 1.65 total horsepower. Both describe this motor, expressed on different rating conventions, so the safe move is to read the plate on the motor that is coming off and match it rather than choosing between the two numbers.

Before you swap it

Check that the wet end you have is the square flange type, since a threaded or C face motor will not bolt up. This part also appears under the numbers BPA450, EB841A and 355010S, so a cross reference from a parts list may lead you here under a different code. Fit a new shaft seal while the wet end is open.

Questions and answers

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

Which pumps does this motor go on?
It is given for the Pentair WhisperFlo High Performance pump, models WFE-4 and WFE-26, on the square flange 56Y mounting.
Is it 1 HP or 1.65 HP?
The source carries both figures: 1 HP and 1.65 total horsepower. Those describe the same motor rated two different ways, so match the plate on the motor you are taking off before you order.
What voltage does it run on?
115/208-230 V, single phase, 60 Hz. It is wired for the supply you have at the pad.
Does it come with a seal or a capacitor?
This listing is the motor. Plan on a fresh shaft seal whenever a wet end is opened, since the old one rarely reseals on a new shaft.
