can anyone recommend a specific type or brand of pump/motor, 1 HP max, for
my current understanding is that there are two speed motors that run at low
(half power) enough to
circulate water and can be switched to the full speed to run automatic pool
(like creepy crawly, pool vac)

One of the pumps on my hot tub is two speed so they do exist. I would
expect this is accomplished with multiple windings on the motor so you
would need a more sophisticated switch as well. The hot tub pumps
seem to be a lot like pool pumps, composite pump bolted on to the end
of an electric motor. I don't have a clue about brands but the
electric motor half seems to be regular electric motors like ge and

The ones I've seen are pulse-modulated so the slower it runs without
stalliing the less current it pulls. I've never come across one for an in
ground pool though. I imagine since it has to be continuous duty it's too
hard to dissipate the heat properly unless it's pulse-modulated, something
that's not good to use outdoors under varying loads (filter fresh/needs
bumping/cleaning, etc.). They run awfully hot by design when they operate
continuously in the hot sun. Won't burn skin instantly but keep your hand
there too long and under your hand, insulated will make you pull your hand
away n a hurry!
I've always found Hayward to have good product that outlasts most others,
around here anyway where they only get used 4 to 6 months per year.

I usually stay away from Hayward products unless nothing else is available.
The pool techs I've talked to say they are not as high quality as some other
brands. But of course, the pool store that sells Hayward says it's the best.

As a second owner of my home with Hayward pool equipment I can say
the first pump motor lasted at least seven years, before I changed
the motor out with a new Emerson brand motor.
Having seen a few Pentair motors running, noticing the silence and
lack of noise I would suggest the Pentair motors today.
My next one will be Pentair, variable speed.
