Product details

The Century B2844 is a 3 HP square flange pool pump motor built for 208-230 volt service. It runs at 3450 RPM on a 56Y frame with a 1.15 service factor, giving a total horsepower of 3.45.

Reading the ratings

Pool motors get quoted two ways. The nameplate horsepower here is 3 HP, and the total horsepower, the nameplate figure multiplied by the 1.15 service factor, is 3.45 THP. Both numbers describe the same motor, so match whichever one your old motor was sold under.

Fit and wiring

It is a square flange 56Y frame motor with a 5/8 inch shaft, 7/16 inch shaft length and a 14.40 inch overall length. It is single voltage, 208-230 volt at 60 Hz, so confirm the supply at the pad before ordering. The motor ships on its own, without seals or a wet end.

Questions and answers

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

Will this motor run on 115 volts?
No. It is rated 208-230 volt, 60 Hz, so it needs a 208-230 volt circuit.
What frame is it?
56Y frame with a square flange, the mounting found on many inground pool pumps.
What does 3.45 total horsepower mean?
It is the 3 HP nameplate rating multiplied by the 1.15 service factor. That figure is often quoted as THP.
Does it come with a shaft seal or an impeller?
No. This listing is the motor by itself. Seals, impellers and pump wet end parts are ordered separately.
