Most efficient water pump?

  • We are currently upgrading MFK. thanks! -neo
Air-lift is considered to be the cheapest way to move water, but that requires a blower.
 
It doesn't have to be submerged, you can run it out of the tank, it just has to be below the water level. It can't prime itself.

Jebao Eco DC-3000 is sitting here next to me.
Sealing (though likely to need some help) 25Gal chemical buckets ready to go.
Plumbing to be purchased once we set these buckets to their racks and get our distances.

Issue: instructions for the pump say to only use it submerged... WHAT??
This is different from what their website (incl. Amazon) tells me, so what's the issue- overheating?
There's an O-ring on the schematic so if the impeller housing isn't sealed.. would really... annoy me.

My whole filtration plan is predicated on mounting this thing to an exterior wall.
Thoughts?
No, I've not tried it in a bucket yet as it requires 1" threaded inlet, which I've not gone to town for yet. Yes, I know, Murphy's law suggests that it won't work at all :)


Q: how does one open the impeller housing? There are what looks like clips, but that seems pretty flimsy/poor if they're expecting me to be able to do maintenance more than once in the life of the machine. Or maybe that's the plan...

Pondmaster pond mag pumps are great. I have a 960 gph one that i am planning to use for my acrylic goldfish pond. The best larger external pumps are the Advantage manufacturing es series of pumps. I am using an es3500 for my koi pond.
