Jebao now doing DC pumps!
- Thread starter porpoiseaquatics

Oh...and I don't know about the other DC pumps but this one is submersible! I have a video of it pumping water inside a tank. Unfortunately it's a 9meg video so I can't post it. I can email it to somebody that has a YouTube account or whatever and you can post it.
I guess the only question now is.....who's gonna do a GB??? If we could get 24 of 1 pump together quickly, I could probably put it with my WP25 order. Jebao says 30 days to manufacture though.

Ok...so I'm going to roll this thread over to The Lounge as a GB and see if we can get there. I'll open it first thing in the morning and we'll see where it goes.

My take.....all electric motors work using AC or pulse DC. You need to switch magnetic field on and off at the right time.
It's very difficult what to tell if a hybrid motor is truly AC or DC. Then add electronically controlled magnetic fields in stators, rotors , armatures to confuse matters more.
For example
Household 60hzAC ..24dc adaptor ....electronic motor control .......motor
120ac..............140DC...200AC...24DC....................20ac and or pulsed DC...........................
The 24vdc adaptor probably a switching power supply takes in 120ac, makes it 120DC, then uses that to run a high freq oscilator ,1500khz, then turns that into DC
Brushless DC motors...The mag fields are microproc switched electronically , so you can tune, shape, time and caress the mag field, not just slap it on and off, The controllers also meter reverse current (ac)to collapse the field faster. there's efficiency somewhere in that. That's why they can be made quiet, .
And a big part of effiency is magnetic technology that crazy powerful. It's a giant free force to react against for the area density. you don't need to power two electric magnets forces to create angular acceleration.

Just one tid bit of concern I would have. If these use a switching duty power supply in lieu of a motor with brushes, harmonic distortion may be a problem. Without getting to technical what that means is the power supply (if not built to eliminate it) causes a lot of harmonic currents to be superimposed back onto the electrical circuit feeding the power supply. Electronics do not like these harmonics and it could result in some problems with other items on the electrical system.
Not saying this WILL be the cause but just wondering out load.

I put a waveline 6000 on my 75G a couple of weeks back. It's silent and the power usage, as well as heat generation based on having to plug my heater back in, from my return went way down compared to the ocean runner I replaced (70-80w vs 280-290w.) The only concern I have at this point is that the power supply is basically identical to a laptop 'brick' and it runs pretty hot so you'll want to make sure it's placed somewhere that it can dissipate the heat and last longer.

I see a problem with these pumps already...the outlet is 1.75". Going to be difficult to find plumbing for that.

With the other pumps I posted those pumps came with two extra adaptors. Not sure of the size.
Edit: Check that...
They are 2.2 and 2.9 cm

Group Buy is now posted in The Lounge.
These come with 3 or 4 hose size adapters depending on the model. DC12000 = 39, 32, 25, 20mm. DC9000 = 31, 25, 20mm.

Looks like just a rebranding of the ones that are being sold under Waveline and Speedwave names already. I have a real problem with Jebao's business ethics. They labeled their circulation pumps with model numbers that were very similar to the Vortechs and this new line is called "Eco Tech". I'll pass.
