Ran across these when browsing for a pump. I've never seen anything this efficient at such a low price. Hopefully they'll be more available stateside soon. Would be great for transfer from RDF to Shower.

I don't like submersible pumps, but I like the Jebao band. I skeptically bought its stainless steel UV, but it works flawlessly, and is at a much lower price than most other brands.
Wow...looks interesting. LP-16000 here in Thailand at 65$, LP-22000 at 68$. I have two submersible Tsrumi submersible pumps.....flawless for about 4 years... I like the no/reduced noise factor with submersible pumps. These Jebao pumps could probably pay for themselves in 6-12 months.... Only technical issue may be the outlet diameter. Looks like nearly 4". My piping is 2". Maybe delivering into circa 15m of 2" piping the head will go way up and achievable flow way down? Will look into this further. Thanks for the post!

Most likely another Chinese pump with vastly over inflated testing numbers. Looks like an axial pump that's probably very efficient at 1/2 to 1 meter and less. The head numbers posted are not realistic. In the past the Chinese axial flow pumps haven't been durable.
The real Batman wears polyester! Don't be fooled by the plastic imposter.
Checking the numbers. Picking the LP35000 rated at 100W. Looking at the pump curves, say at 2m head, the LP35000 would be delivering around 17,500 l/hr or 0.00486m3/sec. Output power of a pump (in Watts) = flowrate (m3/sec) x pressure (pascals). 2m head = 19612Pa. Thus, output power = 0.00486 x 19612 = 95.31 Watts. So, yes an efficient pump at 100W input giving 95.31% efficiency....but not a totally unreasonable number. The problem will be the dynamic head/pressure drop once downstream piping is added. Back to the drawing board.

I have a different model Jebao (dcp-20000). At minimum flow I get 850gph (real, not nominal) at 29W. It's running a small shower so the head is just a few feet.
