Highest pressure submersible pump

[karimwassef]

So far, I've found

Jebao DCT 15000 = 16.4ft
Jebao DCP 18000 = 29.5ft (never used before)
Fluval SP6 = 13.1ft
Alpine EcoTwist PXX5300 = 22.5ft (not sure if reef safe)
Lifegard Aquatics PG 6600 = 22.6ft (not sure if reef safe)

but I need ~29ft or more...

I don't want to stack 2 pumps in series.

[karimwassef]

I can't get a clear view on the Jebao DCP 18000...

some sites show 9m head.. ~29.5ft
https://www.amazon.com/dp/B06XCNGXCX...ing=UTF8&psc=1

others show 7.5m head... ~24.6ft
http://www.simplyaquaria.co.uk/new-j...-dc-pumps.html

also a reference to a DCP 20000 that doesn't exist in the US?

I think I know the answer, but you're not gonna like it.

[ca1ore]

29 ft ..... That's going to leave most pumps wanting, even the big externals.

the answer must be in the form of "the best high pressure submersible pump is "

and the following cannot be "not a submersible pump"... that's an illogical answer than doesn't help.



all other recommendations are welcome.

I think Abyzz might be the only player that can give you that head.

ok. At $2350, I can build a whole section to the house to put multiple pumps in series.

So - budget is 4x my current pump @ $160 = $640

Has anyone actually tried a Jebao DCP 18000 and checked pressure capability?

[2000se]

Yeah but, if it says 29.5 ft head, doesn't that mean the max? Like you'll get 0 flow rate at 30? Thats not even worth it right.

You could look into a diaphragm pump? Those things pump great heights and are self priming.

[karimwassef]

No. I need 29' of head for a high pressure application. I don't actually need to run at 29'. I have a 29' head external AC pump that is leaking and I'd rather go submersible this time around to save the hassle.

Thanks for the heads up. I felt no need to really mention the name of the pump because after getting to know your opinions of pumps, I knew the answer was not one you would be fond of. You later proved that when Breadman03 mentioned the pump. Then again I guess if the post was titled: "Highest pressure submersible pump other than Abyzz" There may not have been a single reply.

I have a DCP-18000, I had also talked to Fish Street about the DCP-20000, they said the 20000 wouldn't be coming to the US.

As for the DCP-18000, it does not handle pressure very well at all, nor do I think it flows what is claimed. I have a 150 gal on the first floor with basement filtration, I use a 2" pipe for the return, it was going up about 5', over about 6', then up another 6' or so. Looking at the flow chart on the box I should have gotten about 1200 or 1300 gph out of it with that much head, I believe I was well under 1000 gph. It wasn't even moving enough water to keep the sump and the tank at the same temp.

So I wouldn't personally look at that option, I've gone back to a hammerhead for my system.

Make sense!

Are you implying that the Jebao claims are not what they claim to be. With an established company such as Jebao, there is no way they would publish that data if the pump did not have the output as claimed.

Well you've got me there!

The price is right, as well as the energy consumption and sound levels, and I do think for lower pressure applications the pumps are OK. But after four of the DCP-10000 and one DCP-18000 I don't think I'll be buying another Jebao. Fool me five times... lol

[karimwassef]

Hmmm. Should be easy enough to measure.

I'll setup a small tub in the back yard with 3 x 10' sections of 2" pipe straight up and drill holes every 5'

As long as I can get it all done before the wife comes home (....), I should have a measure of it's pressure output. At $170, I'll try it and take some pics.

I would drill holes every 2', but that's a waste of good PVC

I'll see where it stops delivering and drill more holes there to get a good read on the last foot and inches.

Always go with data !

[karimwassef]

ok. so I'm satisfied that it's somewhere between 29' and 30'.

I could have gotten more resolution, but I was getting wet and this was good enough.



here is the setup at 20'...



Tested it there and had a water fountain over the backyard... got wet the first time. So more than 20'.

Ran it up to 30' and no water came out... so less than 30'



drilled holes at 5' from the top - struck water.. and then several in between...



can you see the little white stream of water going sideways? I tried to get the green background against it so it would show.

and then took another picture against the lake



then higher... still struck water



got on a ladder.. more holes.. more water... but getting closer

at this point - wife was getting freaked out that I'm up on the rooftop deck 20' up on a 4' ladder and balancing to drill holes in a PVC pipe...

so.. I got within a foot of the top and still had water



with the bottom pipe just at the water line





If I plugged up the lower holes, I got water to go up even further up... so my estimate is somewhere between 29' and 30' which is where it's rated.

so my assessment is that, at least brand new, it delivers the 29'+

It might deteriorate over time, so I'll redo it in 6 months or so.

Just sharing my own experience - data is always best.

Awesome test. Thank you for sharing. You didn't by any chance check how much power the pump was using at full head height, did you? Would be very interesting to know if power usage goes down like AC pumps.

Thanks,
Harry

[Sayaquariums]

a Leader BVP Pump can always handle this kind of job.

[jason2459]

Nice job. Exactly what I have plans to do this summer with several pumps and a flow meter testing flow at different heights and finding max head cut off.

FWIW, I've been using the dcp 18000 on my MTC MVX mazzei venturi skimmer and have found it to handle the head pressure quite well. Very impressed with the pump.

Flow has been around 300gph and watts drawn around 147watts and pulling around 28 to 30 scfh of air at 100%. So if not pulling air the gph would be higher.

At full power under high pressure it still pulls near max watts (145ish from the outlet) which is counter to an AC pump which watts drawn is drastically decreased as head pressure is increased. Same experience I've had with a few other DC pumps.

Abyzz A400 is by far the most powerful internal pressure rated pump by a long shot. It will blow away every other internal pump that is presently available.

[karimwassef]

Thanks Slief. I don't doubt it. But the poor need bread too

I didn't check the power consumption, but the controller provides a power setting and I set it to max = 130W. I don't have any confirmation what it actually draws. I'll put it on an Apex outlet and check.

Agree but he's already very much stated he is not buying one. I would love one myself. Maybe someday.
