MTC skimmer club!

Didn't get to wrap up the single 584 very well here. I've been under the weather pretty bad.

But the single 584 did ok.

For comparisons
Waveline DC 12000 @ Level 11 w/ 584 mazzei
Air draw: ~20-22scfh
Max head height: 22.96'
Watts used: 142wattts (w/ adapter)
Skimmate produced: ~4.5cups/day dry



Waveline DC 12000 @ Level 11 w/ dual 484x mazzei
Air draw: ~28-30scfh
Max head height: 22.96'
Watts used: 145wattts (w/ adapter)
Skimmate produced: ~3cups wet/day


Mag18 with MVX stock 684 mazzei venturi
Air draw: ~12 scfh
Max head height:16.85'
Watts used: 62-63watts
Skimmate produced: ~3 cups dry/day high side

Mag18 with 784 mazzei
Air draw: ~14scf
Max head height: 16.85'
Watts used: 65-66watts
Skimmate produced: ~3 cups dryish/day low side


Waveline DC 12000 @ Level 11 w/ 684 mazzei
Air draw: ~24scfh
Max head height: 22.96'
Watts used: 147wattts (w/ adapter)
Skimmate produced: ~5.5 cups dry/day



Waveline DC 12000 @ Level 11 w/ 784 mazzei
Air draw: ~26scfh
Max head height: 22.96'
Watts used: 150wattts (w/ adapter)
Skimmate produced: ~6 cups dry/day
 
But now I have dual 584s installed. Pretty crazy.

A single 584 was pulling about 20ish scfh of air. Dual 584s are right now pulling about 15-16scfh each so about 30-32scfh total which is about 6scfh less then the Aquamaxx EM300 I had was pulling.

Watts drawn right now are between 147-148watts which is on par with the 684 at full power. So, about the same flow maybe. Definitely a lot more then previous as I had to quickly open up the gate valve a good amount as the water level quickly shot up and flowing into the collection cup. Which I'll have to clean out in the next couple of days and start tracking the skimmate production after I get the water level dialed in.

But that air draw.... It's noticeably the most air in that body yet and swirling around like crazy. Much more microbubbles escaping then even the 784 at full power. Definitely not a setup if your sump can't handle microbubbles. I designed my sump specifically to completely stop any amounts of microbubbles from getting to the return pump and this is the perfect test for it and is passing with flying colors.

Took video of starting up. All the crackling at the beginning is the water getting sucked out of the airline tubes as the injectors are underwater a bit. Seems to be keeping them cleaned out ok.

Thanks for sharing Jason...Hope you feel better soon !
 
Problem with Waveline12000

Problem with Waveline12000

The flow rate from my Waveline 12000 seems to change each time the pump restarts. It also seems to be on the low side. I just hooked up my Kill-A-Watt and the draw at full power (11) is only 109 Watts. The spec states 132 watts at full power.

Possible bad controller? Power Source? Pump?

Is it the Apex ready version? With out the Apex ready upgrade it will have lower rated max head height.

If it is the Apex ready version that is very low. Even in 14-15" of water at 100% going though the 584 mazzei which is more restrictive then the stock 684 mazzei I was still pulling over 140watts. Averaged about 142.

With the 684 mazzei in about 8" of water the waveline 12000 apex ready was pulling about 147 watts.

Those are all with adapter. That ratting of 132 watts is after adapter FYI. With adapter its rated around 150-155 from the wall.

Could be controller or the pump itself. I'm not sure. Unless it's not the Apex ready version or it is the Apex ready version controller but the prop in the pump didn't get replaced.
 
On a side note, Jebao has out now a DCP version 18000 lph with 9m (29.5') rated head height!

I will have to try that out! Only thing is it is not Apex controllable which is a little plus for me.

It is not the Apex ready pump. It appears that the non-Apex actually draws more Watts. 170 at full speed. I bought it on Ebay Here is the link.

Keep in mind that may be max watts the pump is rated for not the power supply. Also that's at full speed with 0 head pressure. Watts drawn is always less as head pressure increases which means flow decreases. I'm pretty sure the sticker on the back of my waveline is also well above 150 max watts. I'll have to look later.
 
Yep, here's the sticker on the back of my waveline 12000. Only thing I think is different is the controller and prop assembly. Both come in the Apex ready upgrade kit.

Using a Waveline DC12000. I did some experimenting with the pump. I disconnected the line from the pump from the skimmer and just ran the pump into my sump. The watts drawn quickly went up to 170+. It seems that the back pressure from the skimmer reduces flow and therefore the watts drawn? After hooking it back up to the skimmer the draw again dropped to 101. Why wouldn't the draw of watts stay high even if back pressure is created? Also why would the watts drawn be the same at levels 7,8,9,10,11? The pump draws 1010 at each of those levels.

Does the gate valve on the return from the skimmer create back pressure on the pump?

The water level in the skimmer will put some back pressure yes but it is mainly the plumbing especially the injector. The watts used should go up slightly unless the head height has been capped. Interesting to see your watts used with out being Apex ready vs mine that has the new prop. Shows the head height was indeed improved.

Pipe size, every fitting,(90s, unions, ball valve, T, etc), the injector itself, hight up it has to go, the water level in the skimmers body, the water level running in the sump, etc ALL puts head pressure on the pump. Its a tremendous amount. Especially the venturi injector. Its about 3/8-5/8" or so which is a very restrictive opening to go from 1 1/4" output on the pump to go through.

Why having a pressure rated pump is recommended and if internal a pump with as high a rated head height as possible. Flow rate alone won't do it.

Also to add quite a bit of the water flow rate is also replaced by air flow rated.
