The little Giant pump really leaves a lot to be desired especially
how they get their head height. They reduce pipe size to a diameter
half of what the intake is, so they are increasing pressure but at the
same time decreasing volume so by speedingupo with a pressure increase
the water flow thewy are able to push a smaller volume of water
higher.....this amounts to pushing a pump continually on its max
limits. I do not know about LG pumps in sal****er but they have a
terrible reputation with ponders in general as to being problematic
and energy consumers a compared to other pumps.

Another hting is the Dolphin pump uses Emerson motors......which are a
bottom line of economy motors, not nortoriously noted for longevity in
lots of applications. The Sequence line of pumps use Baldor motors on
their better pumps which is pretty well a well accepted industry
standard and known for longevity. Sequence does use othe rbrands
ontheir lower line of pumps Value line or Value flo or something like
that, and if you compare specs you will see those pumps are also
going to consume a lot more watts overall to attain the same
performance as a Baldor powered pump does. Its allin the efficieincy
of the motors......Personally I would wait and save up a bit more
money if I was short and buy a top line pump with better energy
consumptions figures and performance, as iat wil save $$ in the long
run.

I have a heap of Sequences in use around my ponds here and they are
trouble free.....

Good point. I think one of these two will work. I'm leaning towards
the smaller one.

They are both external, so air cooled.
