So I jumped on the Jecod/Jebao DMP-40 train. These are my thoughts:

The backend:
I originally designed my plumbing system specifically to accommodate Ecotech MP-60 pumps, should I or when I needed them in the future. I have always loved the Ecotech design while being a vocal advocate for more practical pumps that deliver on longevity and quality for the price one pays. My opinion of Ecotech being that they do deliver nice quality products, the price point has always been lofty. Much like most quality things, eventually some flattery will come along in the form of imitation or replication.

From my perspective, the magnetic coupling of wet and dry sides coalescing into a single unit has always been the appeal of the Vortec pumps. The countless modes of wher wher, wizz, wizz never added any value to me.

As for my experience, I have only ever owned a pair of MP-10s with the white controllers and
WiFi so I could link them together. They were quiet for the time I had them but they would barley stick to ⅜” glass. They would fall off randomly and the cords would pull out of the body. I mean they give you tiedowns and zip ties to clamp down your pumps in case this happens; you would think the cord that they tell you to tie it up by would hold the weight of the pump when it does let go but no.

I did not let the falling off of the glass deter me. I did allow it to influence my future purchases. The MP-10s let me down in the glass thickness department, I wasn’t going to let that happen again.
My tank has ¾” thick glass. So for me a couple MP-40s were not going to cut it. I needed MP-60s. I needed the MP-60s for their strength and ability to hold onto the glass, not for the flow.

Getting to the point:
I ordered two DMP-40 pumps which claim to work with 19-21mm glass thickness. That is 0.748-0.827in in freedom units. There is a jump up in glass thickness from the DMP-30 to the DMP-40. All of these pumps include suction cups on both the wet and dry sides.

I thought that the DMP-40 would have the same clamping power as the Vortech MP-60 based solely on the glass thickness ratings.

My expectations were too lofty for this potentially great pump.

I have been fiddling with them for a few hours and they must be perfectly aligned or they do not function at all. When perfectly aligned they fall off when changing speeds. I have to start them at 30% and ramp them up, I can not start them at say 70%.
On thinner glass, they may work perfectly, but on my tank they fall short.

I got an error… Er03… no big deal, let me check the manual…

No joke, the manual skips right over Er03. I am pretty sure this means some kind of magnetic coupling misalignment.

On thinner glass, they may work perfectly, but on my tank they fall short.

Flow:
The flow is nice, powerful and wide. I would recommend (provided they stay on the glass).

I am still not going to buy two MP-60 pumps even at 20% off right now.

If anyone is looking, a nice new set of DMP-40 pumps will check most of the boxes.

I have Err 03, I don’t know how to clear it. . And it’s not in the manual. I’ve depowered the pump plugged it back in and the error is still there. I bought the DMP 30 and it definitely won’t work on 19 mm glass like it’s supposed to.

Unplugging and plugging it back in always worked for me. I don't think you can use the on/off button to cycle the power and clear the code. The error would come back after I ran the pump again under the same conditions for a minute or so.

I purchased 2 of the DMP-40's and ran into the same magnetic coupling issues but on my 1" thick acrylic. I purchased a pair of 3d printed cradles off of Etsy for $20 each that stick to the outside of the tank and support the dry side to hold it in place. Problem solved

Go grab some of these

Not to sound argumentative but as far as glass thickness it clearly show less than 20mm:

$340 for a pair DMP-40 and some 3D printed brackets or $1500 on a a pair of MP60's solely to get them to only stick with just magnets.

sorry wasn't commenting on your post....just OP's post about glass thickness.....LOL...

FYI- Er03: Pump idling – Check if the pump is working dry

Almost everything jebao/jecod uses the same error descriptions on a lot of their products.

Wouldn't be surprised if the controller has the function but not actually required for this product lol.

Perhaps you are looking at a different variant. Mine clearly states 8-21mm. 3/4" is less than 20mm anyway.

I like No. 2........the "A" is always silent......
