DIY Red Dragon Pumps, gathering ideas.

[JCTewks]

but are the newer models using impellers made differently? someone earlier said that they were all the same impeller. if you look at the laguna website they are different model numbers for the power jet and WG pumps. go to the AZ ponds site and they are selling all of the same model number for different pumps at different prices. I'm confused.

 

[hahnmeister]

Right, but there is a good chance that there is a new impeller that will mate exactly with the old ones. They look the same, just a different color or something. Even if they are not exact matches, it may be a bit like a maxi-jet pump... you can swap impellers freely between models.

but do you think they'll be saltwater safe? i'll see if i can get in contact with hagen or askoll and find something out. I'd rather not buy 10 different impellers to find out

 

[hahnmeister]

According to smjtkj above, the max-flo ones are saltwater safe. Im awaiting an email response from Hagen right now.

I am just going off what some web sites advertise! Here is one in Austrailia. The chart clearly shows the 9000 model and others
as saltwater safe and also in line compatible. The 9000 is the same as the 2400 and so on. Also, someone on ebay was selling one and was advertising that it was safe for fresh or salt water.

It only mentions a ceramic shaft, Please let us know when yours gets in if it had that brass collar in the impellor. You def can tell its there or not looking at the face of the fan.

 

[Creetin]

Ahh it was easier than i thought. LOL I just cut off all the blades then cut thu the center around the brass coupling, and right thru the plate and gently pryed off the fan itself leaving on the tension clasp. .
The fan is toast, But if youre mesh modding it anyways all you need to do is drill out a pvc/plastic/acrylig circle the same diameter as the old one and drill a bunch of holes on it.
Now I probably could have found a better means to attatch the acrylic ring around the impellor, But i just glued it in place, I'll see how it holds up. It needs a good rinsing, But notice the brass dust?
Here ya go the mesh modded laguna 2905. LOL it should rip some air!!!

 

[hahnmeister]

Yeah, I wonder what even with the stock volute these things can do... the stock volutes on some of those larger pumps are pretty large in the first place.

Hook it up Creetin! LMK if you need me to send you a 10-100scfm meter! Do you have means of testing it? Test container, Kill-A-Watt, airflow meter...???

Which model did you mod there again?

 

[smjtkj]

Cool! So you just glued the ceramic shaft to the acrylic disc? Is there another ring or something holding the mounting plate to the ceramic shaft?

Hahn, that is why I got the 2400 max flo model. It has a larger volute area that the rest of them and also has 1.5 inch input and outputs! I was hoping that the results would be good enough without a lot of fuss.

This is the 2905, I have a new impellor for the 5000 coming in as i broke that one's ceramic shaft.
I have a 10-100 scfh meter already, Need to pick up a killowatt meter at harbor freight. Lucky for me i have one local.
The glue is still setting, I'll get some pics up tonight when i fire her up. If klaus is getting 5000 lph on basically a 5000 i wonder what the 2905 here will pull since its basically the same size magnet, but 1.5 times longer spinning at a little higher revs i hope to see 7000+ lph hopefully more and reduce the water flow.
The housing seems big enough to handle all that air and water, and the 1.25 and 1.5 inch ports should be plenty as well.
But it is just speculation at this point.
Look around 8-9 oclock easern time tonight for the pics and maybe vid.

I left the tension clasp on as it is a hex and easier to glue the plate to so it would not slip.

This model has 1.25 and 1,5 inch ports.

 

[spykes]

cool man, but what would you do if you wanna use this pump as a water pump?

 

[Creetin]

You could still use it as a water pump, But you might lose some performance. Still better than having that brass fitting in there.
I would gladly give up some gph knowing i have the brass out.

 

[smjtkj]

Creetin I was wondering what is holding the impeller mounting disc plate to the impeller and ceramic shaft.

 

[Creetin]

Modded or unmodded?

Looks like i am getting 1,699.2 LPH with just a hose stuffed in the end of the pump. Let me make some adjustments, and i will get back.

there is a carbon bearing i think at the mounting plate. It's what holding the impeller without the brass tension band right now.
