External pump push/pull?

3' horizontal is supposed to be equal to 1' vertical when figuring pumping
"head", so 25' horizontal + 4 ' vertical is ~ a 12' head you are dealing
with, as wellas the other 25 ' on the other side of the pump
Gale :~)

If I set it up as I planned, sucking water through
about 50' of 2" pvc and up about 4', am I going to have problems? Would
it
make a significant difference if I had the pump in the middle, 25' from
the
pond, but before the slope? FWIW, the pump is rated for a little less
than
3000 gph at 4' height.

The chart from sequence has a friction loss of 3 - 6 ft per 100 ft of 2"
pipe at the flow rate for this pump. Is your horizontal/vertical loss an
additional factor?

The #'s I quoted below came from a "pond construction" book I read a few yrs
ago and I think they were for submersed pumps (don't know if that makes any
difference for "out of pond" pumps) - seeing as how your info is newer and
for the pump you have, I would use it - there may be some one else in this
group that knows for sure - Good luck

Whew! I was thinking I'd need ANOTHER new pump. Actually, the chart
indicates friction loss in that range for 1" pipe and high gph, so buying 2"
pipe may have saved me.
