Thanks. I went to that websight but I still get lost. How about I just
post the info of what I'm thinking of getting.

I'm thinking of getting the Oase Aquarius 2000 pump which is rated at
2000 GPH.

I'm going to be hooking it up to an Oase 1 inch Frothy fountain nozzle
which supposedly has a maximum hieght of 44 inches when used with the
Aquarius 2000 running at maximum.

What do you think the average flow rate would be for this setup?

months. So far its doing good. It has a baldor motor which are good
motors. Ive worked with them in manufactoring for years along with
Reliance. I know of some of these motors that have been running
continus duty for over 20 years

head any higher because it's running at maximum

Your theory is pretty much right, pressure head includes the height
of
the plume or fountain, but may be flow losses in the head itself.
The foam head can be self limiting because of two things:
1. Internal restrictions
2. External loss due to turbulent output
The head has pressure loss to produce the foam effect. Therefore
there
is back pressure, which shows up as flow somewhere else in the
system.
In other words, the water comes out someplace else if it can. If it
can't then the pump efficiency drops off to dump the power; it
cavitates. *
