Tell me your experience with Deepwater Aquatics DC Pumps

I disagree, but your welcome to your obviously biased opinion. None of the Jebao products I have had were even close to what I would call reliable. Typicly lasting 6 months or so.

No bias at all, I don't own one, never have, just tons of research.

I'm not saying they are better, just similar. Jeboa have sine wave pumps now and the older models many have run for years in their thread. I also trust Rons advise.

I have a reliable ac pump now that I bought used for a hundred bucks over 10 years ago and its still like new. But I think I'm at about 110W so I have been researching DC pumps of all makes so I can save 50W. I have not found any of the affordable ones yet with a track record like what I have. None are reliable enough for me to make the switch, but I keep researching. I really would love a DC pump that is not stupid expensive like red dragon or abyzz that will last a decade.

The Vectra L1 put more heat into the water than I was comfortable with.

Love my Iwaki, I just bought a md15 for my calcium reactor. Holy cow is the thing hot. I mean really hot.

If it wasn't just feeding a few small drips into sump and was in some high flow usage, it would definitely heat the water up.

The test is if you can keep your hand on it for 3 seconds its good to go lol its ridiculous.

Funny the md55 is barely warm.

Why not make the switch now and keep the Ford Excursion (I mean AC pump) as backup? :dance:

In the time I was gone I was researching how much 60W at 15.6 kwh cost a year running 24/7.

If a DC pump last 3 years, it pays for itself


Iwaki's are the gold standard, not sure I would compare to a excursion LOL but I get your point.

Not much beats Iwaki or similar for high head pressure rated systems
 
I had a ac pump that was 15 years old at least pumped 3000 GPH @150 Watts. I only replaced the seals Twice during that time. I agree none of the reasonably DC pumps are going to last that long. I switched to a DC pump for the same reason and I wanted an internal pump on my new build. With electricity here being double your rate, it just made sense. At the setting I use it at most of the time it uses only 1.58 kilowatts per day. At this point I have had my BLDC8 for 2 years and am happy with the choice. I have not even cleaned it, although I should as preventative maintenance.

It pays for itself in a year. Sort of made my mind up. Ive been sniffing this for a while, regardless of reliability I'm ahead either way.

I just ditched MH and VHO after 25 years at 220W for VHO and 525W for MH and went leds which is saving huge.

I may find a cheap little dc puimp for my cal reactor despite juts getting a new small Iwaki burning 30w for a little external DC to.

Just get an oversized DC pump and split the line to the reactor. I've never needed a reactor so I'm not sure if turning off the reactor during water changes or feeding will be a negative.

Its not the feed, its the circulation [closed loop]

little mj 1200 feed has been going 8 years ;) same impeller and still tight inside.

The eheim 1048 impeller failed last year but I was able to band aid it up with spare parts.


I'm trying to figure out which DC pump would give me 900 gph at 9' I understand I want in a perfect world to oversize it and run it at 60%

That's easy! I can help you figure that out! :thumbsup:

You I would trust, its the pumps real world rating that I'm guessing at.

limited by 1" plumbing and from what ive read by people with flow meters, 400-600 gph is what I can expect at best out of a 80W DC pump.

Probably would not hurt to run the bigger pump and run adaptors from 1 1/4 to 1" it will add to the head pressure but ill get more flow

An RD3 150 would handle your needs without an issue and do so right around half power. The specs and flow curves on those pumps are very conservative. Klaus takes flow testing very seriously. The flow and pressure test setup at the factory in Germany cost more than most peoples cars. LOL. It is however a 1.25” output so you would have to dumb it down which I would suggest doing as high as possible to keep the friction losses to a minimum in order to maximize the efficiency of the pump. Here is the flow chart and these rating you can take to the bank.

You can never go wrong buying the best.

I had a feeling you were going there ;)
 
Also on the topic of the deepwater pumps. I’ve been considering one as a backup because I don’t think the waveline I have will be enough. After researching quite a bit I found out they have changed the controller on all models but the BLDC15. They are still working on the BLDC15 which is just my luck. Has anyone bought a deepwater pump since the new controller?
 
I purchased yesterday and Marine Depot states its the new controller. I emailed Deepwater and they said MD has not placed an order in a while so they believe its the old controller... we shall see in a week.

I'd be ****ed at Marine Depot if it's the old controller. If it's the new controller post up a review on here or PM me what you think. I might start a new thread to see if Deepwater has a timeline on the new controller for the BLDC15.
