Sometimes was labelled model SD-15-2N11CC or SD-20-2N11CC (but is all the same pump and motor) when at the request of certain spa makers it worn stickers saying 1.5 hp or 2.0 hp, fyi. Keep in mind true output is always measured by volts x amps = watts, not by what HP sticker was applied. Years ago this was labelled 1.0 hp and it will develop 2.0 Brake Horsepower so is sometimes labelled 2.0bhp and SD-20-2N22CC.
The Hi-Flo series is available in single and 2-speed versions, and with a 6" leaf trap for swimming pool, pond, or water feature use. This pump is often labelled SD-20-2N11CC. Replaces old Superflow with same ratings.
Sometimes ships with 12.2 amp US Motors motor and sometimes with 10.8 amp AO Smith motor. Both are shown in the photos. 10.8A has capacitor can on top at 12:00 position.
