Tunze nano mod
- Thread starter mr pink floyd
- Start date
Skydancer thanks we know we can always count on you. How about testing the full blast mod without the stopper to see how much increase? Did you check the power draw to see if there is any difference?
The flow increase from the full blast mod of course can vary based on how much is the openning cut.
BTW, credit should be given to our resident young prodigy, Mr. Pink Floyd who started this whole thing.
Did you say 6055? I was thinking more like modding a 6080
At 20w standard power draw who knows what that thing can do. It may blow all the bigger Tunze streams pumps out of the water and put Tunze out of business

Ill take credit for the original mod and partial for the wide flow mod, but the rest was jacmyoung, stop being modest, you had the tools and the abilities to make my mod 10x better.

Has anyone tested the power draw on these pre and post mod? Roger said in the other post that the 6025 has added drag.
"The 6045 is different from a 6025 in the length of this pipe, the propeller reversal mechanism and the size of the potting area over the motor coil. Other aspects are the same. The 6025 has added drag, hence the higher wattage and the lack of a reversal tab, the drag alone will reverse the propeller."
I would bet that the amp draw in going down while the flow is going up.

Removing the stopper makes no difference on the pump's performance. I guess it is so small if any that doesn't show up in the readings.
The power draw on the 6025 DID NOT CHANGE regardless of the mod. The unmodded 6025 drew 7W and so do the 6025s with the various mods...
Ditto on the credits, but you my friend deserve the "STOPPER" award of the year.:beer:
I thought the stopper might have blocked some flow because you tested the 6025 with standard mod to be 1,111gph, and with wide flow and the stopper to be 1,078gph. Now to think of it they are so close they are within the margin of error under this test.
While the stopper worked perfectly for its intent, it still has the normal startup clicking noise when corrective action is needed. If put on a rapid wavemaker that can be an issue. I don't know if you noticed that. I am hoping to find a way to reduce that noise.
One thing seems clear, both 6025 and 6045 probably have the same drive unit/motor since they both draw 7W, regardless what kind of flow they produce. The added drag or lack of it did not make much difference.
Let's do a quick recap:
We so far have done the following on our beloved 6025s: the basic mod (TBM), the wide flow mod (WFM), the full blast mod (FBM), the stopper mod (TSM), and I'd like to add one last bonus, the auto clean mode (ACM).
Compared to the Tunze advertised specs, TBM has increased the 6025's flow by 68%, FBM by 86%. As put by one of the American Idol's contestants: "not too shabby"
BTW I am not an AI fan but the rest of the family are. I can only hope this thing come to an end one day.

One thing I'm wondering about. Will the Stopper mod work without the wide mod implemented?
In other words can one just do the standard mod, the full blast mod and the stopper mod and have the 6025 auto-correct every time?
BTW jacmyoung, you may want to edit your last post and give a different 3-letter acronym to your stopper mod as it shows the same with the standard mod.

OK.. I couldn't wait till the week end so I did the test today.
I went by skydancer's specs and measured 3 gal of water out of the bucket keeping the water level even as it pumped it out.
The only thing I did different was, I ran my test in saltwater (1.025 sg, I had it handy for a water change), and i did 10 test runs throwing out the highest & lowest times.
I'm VERY disappointed in my findings.
The 6045 slandered flow average was 850.89 GPH.
The 6045 Modded flow average was 1165.67 GPH.
FWIW I think you should just get a 6025 (save $30) and do the mods listed in this thread. Looks like you will get the same flow rate.
I did not test the Wide flow mod as I want my stream to shoot 3 ft to the center of my tank.
here's a pic of my modded 6045, I have the protective grating on the end of my housing to catch the impeller on start up. (not pictured)

This here really makes me mad... I wasted $60 for nothing. I could have just gotten 3-6025's for the same price.
OK... OK.... HMMMMMMMMMMMMMMMM.......
I'm just trying to get my blood pressure down.. I'm calm, I'm calm........
I'm just very disappointed in the results.. I think we have been deceived..

There will always be that clicking noise from the stopper when the prop correct itself. The trick is to use a softer more pliable material as a stopper. There is a reason why I suggested a rubber bolt or weed wacker wire instead
You basically just want something to give a little resistance to the propeller to stop it from spinning.
My current MJ mods are silent and with no damage to the props no matter how often they stop and restart.

Just as I suspected earlier, opening up the bottom may do more good in improving the flow since it is an area closest to the prop blades. As my high school science teacher once said water (or pretty much everything in nature) will take the path of the least resistance. Less travel means less resistance.
Your flow measure is higher than that of skydancer probably because you opened up the top too.
Another thing to consider is to buff out any rough edges when you do the basic mod. A smooth surface will reduce friction.
dhnguyen, thanks for that info.
