Tell me your experience with Deepwater Aquatics DC Pumps

sleepydoc said:
You're right about the interaction between the controller and the motor, but I would also add that one of the reported methods of controller failure for the jebao pumps was overheating, and even cheap metal conducts heat better than plastic.

I've also noticed the similarities between the various controllers, and would be interested to see a tear down of them to compare.

I read an article once that compared several of the square USB power supplies like you get with an iPhone. They all looked virtually the same on the outside, but there were significant differences in the quality of the components on the inside, so you can't draw too many conclusions.

This is very true and like you I would like to see a tear down myself.
 
The Deepwater-pump has nothing to o with the cheap Jebao-pumps. Thats complet different Factorys. I know the guy, where build the pumps for Deepwater now longer as 7 years... The problem of the Design for all chinese DC Pumps and controllers : ..... he look all as the same. The Chinese wait on a stupid western Guy, where make a new Design and so, all chinese copycats jump on this new train :-)

best regards ... Klaus

did you cut and paste? lol
 
I like the quality of execution of Deepwater Aquatics BLDC. The housing is filled with minimalist no extra forms.

It's not a clone Jebao, is a different technology(sinusoidal signal).

It is doubtful that Vectra Ecotech will improve the impeller, probably will change color(as and body pump) impeller and titanium shaft.

I think Ecotech has not selected an engine of bad quality for new pump. Therefore, it is logical to assume that Deepwater Aquatics reliable pump.

...Also this pump has the best performance of energy saving and performance. Found only one pump which has the advantage that AquaBee.

I find the different wattage used between the two pumps iteresting since the pump motor is reportedly same.
 
I would think that if the internals were truly different, then companies would want to market on that info. My guess is the are all the same.
 
I read this entire thread and re-kindling interest.

Any new info ? Anybody using the Deepwater pumps for a more lengthy period? Etc.

Looking for a pump for a 150 tank , with a basement 75 gallon sump= 14 head pressure with height ( 9 feet) , spa-flex hose friction, a "t" , and two 45's.

Thanks

I second this. I am in the market for a new pump and not much info on these. I have similar head requirements and the BLDC15 may fit the bill. Would love to hear some reviews
 
I bought 2 (a DC10 and DC12) since 2 was less then some of some of the other brands and for redundancy/back up. I have only used the DC10 so far and am pretty happy with it. Dead silent when not touching the sump walls and my stand is not enclosed yet. My 70 gallon sump it turns out can barely handle it on full power. I was just figuring out how I can measure the actual flow it is putting out. I have a killawatt meter, so will test the power consumption and flow and post in a day or 2.

I am using flexible 1.25" tubing for most of my return line, although it does currently go through a 1" bulkhead with one 1" fitting. There is only one 90 degree fitting and union which are 1.25". This set up is temporary as I will probably eliminate to bulkhead and feed 1.25" all the way to the tank without any 90 degree fittings if possible.
My set up has 5 of vertical head and an addtonal 3 feet of tubing. Since it is pretty large tubing fir the most part, I am gussing 8.5 feet of head.
 
I have the BLDC7 and it has been running for over a year. I don't remember exactly when it was turned on but I purchased it in August 2015. It runs very silent, so silent that I have completely forgotten about it. My desk is right in front of the tank and I hear every sound the tank makes. It is also part of the living room where we watch TV, the old pump would interfere with anything on the TV. It has shut down once because the ATO ran low. Probably would have cooked my other pump but the protection did exactly what it was supposed to do. I will say that I am disappointed with the flow rate, was expected more but that might just be my fault for getting the 7 instead of the 10. With that thought, this spring I will be upgrading this to at least the 10 and use this as a maintenance pump. The controller is in a nice metal box that can easily be adapted into a nice cabinet unlike those cheap plastic types. Overall, and I am by far no expert, I would recommend these pumps.
 
I picked up a BLDC8 & BLDC10, planning to run them both in case one failed. I have not used the 10 as then8 was more then my sump could handle. So far I am very happy with the BLDC8.
