Product details

The Century B2977 is a two speed C-face pool pump motor, 2.5 HP on a 56J frame, running on 230 V single phase at 60 Hz.

Which pumps it serves

Century lists it for the Hayward® NorthStar built after 2008, the Jandy JHP and JHPU, the Jandy HHP and HHPU, and the Jacuzzi Magnum Plus. Match the frame, the shaft and the voltage to the motor you are removing before ordering.

How the two speeds work

High speed is 3450 rpm and is switchless. Low speed is 1725 rpm and runs through a microswitch. Running low for daily turnover and reserving high speed for vacuuming or backwashing is where a two speed motor earns its keep.

Construction and dimensions

It is a permanent split capacitor motor with sealed ball bearings at both ends, a rolled steel frame and a drip proof enclosure, with a 1.3 service factor. The shaft is 7/16 in threaded 303 stainless steel, 0.625 in in diameter with a 2.57 in extension. Overall length is 13.05 in over an 8.00 in frame, which is the measurement to check against the old motor.
