can anyone recommend either of these or another alternative. Head height will be about 1.3m and wanting flow of 2500-3000lph

these are the 2 I am looking at in the 6000 or 6500

any suggestions appreciated

I use the Boyu eco variable which is very similar to the Jebao. I think they come out of the same factory since all parts and specs are the same.

I have been very happy with the two I have. They pump well, don't use much power, are super silent and have not failed yet.

Jebao are pretty good pumps, quiet too.

Their head vs flow charts are somewhat conservative.

To that end the DC6000 should cover your needs, but for $15 more you may as well get the upgrade to DC12000 and you can just throttle back the flow as desired using their DC controller.

DC pumps are inherently quieter and more efficient than other AC pumps.
