Best pump for the job??

[whatcaneyedo]

Eheim pumps can be internal or external. All of the others mentioned so far are external only.

I personally use a Mag18... Good Price, quiet and reliable. They say it can be ran internal or external. Mine is internal.

Most LFS carry this series, so even if you have issues, replacement parts or new units should be easy to access.

If you were to go this route I would go with a mag 24 over the mag 18.

Head Height Mag 24 (in feet) Gallons per Hour
0' 2175
1' 1910
3' 1710
5' 1630
7' 1345
10' 1100
15' 720
18' shutoff

Placing the sump as high as possible will reduce the need for a larger pump, however maintanence can become a problem if the sump is placed too high. If you're looking for new ideas you could check out my recent build where I stacked multiple sumps with the main circulation pump at the top and a secondary pump at the base. I used a RD 6.5 at the top and a AquaBee 3000 at the base, combined I'm using less than 70watts with a DT return of about 800gph. Also both pumps make zero noise, are internal and generate very little heat.

Thanks guys for the help so far.

70watts / 800gph for a basement return pump?

Yeap, and that's both pumps combined. Measured the wattage myself with a Black & Decker power monitor.
