Thanks. You put me on the right track.

If these are large submersibles, you should be aware that they can heat up
significantly at such high head loads. This could cause problems with
maintaining a proper tank temperature. Just something to consider.

Is there any relationship between the head pressure you use
the pump with and the amount of electricity it uses up ?

If so, I would guess the relationship would be that more head
pressure would cause LESS power consumption for the same pump.

I remember that this thing with submersible water pumps and power
consumption was going against the, so called, "common sense" ;-)
