DIY Red Dragon Pumps, gathering ideas.

[JCTewks]

I believe that hahnmeister is doing some preliminary testing of the 4200...he states that it will do around 6000lph...so almost double what a dart can do I think that you 'll get the max performance if the water level is around 36".

 

[dew2loud1]

I'm getting a little over 3000lph now, but thats with forcefeeding with the dart and like I said it likes to overheat with that much air.

 

[JCTewks]

IIRC, the 4200 will do 6000lph without force feeding...I'd guess that it can prob handle 7-8000lph force fed before it chokes...now that's a lot of air

Wow insane! Hans hows this going?

 

[hahnmeister]

Well, I had to troubleshoot the 900 and AC70 first, but the 4200 is next up to get figured out 100%.

with that amount of air passing through your skimmer, there is a distinct possibility that you will be referred to as the foam-meister

 

[hahnmeister]

...not my skimmer... I just helped out with some 'revamping'...

Back to my skimmer design:

If I use a 2400 does the following sound good?

a. 12" square skimmer body 30" tall with a dome top going into the neck.

b. 10" cylindrical Bubble diffuser 4-5" tall

c. 6" neck 12" tall

 

[JCTewks]

IMO, You'll want a larger neck...say 8"dia x 12-14"tall....a 6" neck will handle 2100lph, a 7" will handle 2700lph, and an 8" will handle 3500lph. 7" would be the smallest I would go, but you'll be able to adjust for dry skimate easier with 8".

Thanks Jeff, I apprciate the info.

From reading this thread, I gather that volute mods on a 2400 are as follows:

4" ID, 1 1/2 to 1 3/4" thick, with 1 1/2" tangetial inlet and outlet

For some of you that have been running these pumps for a while, on a 2400 pump does this sound right or do you have other suggestions?

How many layers, size, and kind of mesh is working best over the long haul?

 

[billyzbear]

The inlet and outlet on the 2400 is 1 1/4. I made my skimmer with a 8" neck, 10" body and 24" total. With my pump performance went down any taller.

Did you use the stock volute?

 

[dew2loud1]

Just got my 4200 today, haven't had time to mess with it much, full out all water it pulled 140 watts, messing around with a super restrictive euroreef venturi (which fit perfectly into the inlet) it only pulled 40 watts.....But of course hardly any water or air as well.

Trying to decide what diameter housing this beast needs....

Oh yeah and be careful when messing with these, you can't hardly pull your hand away!!!!

How much air you are wanting will determine the volute size. Try using the stock volute first...the volute on the 4200 is pretty large and should be able to handle quite a bit of air without modification. What size skimmer will you be using this on?

TOTALLY OT question (you can PM me if you like)...is OSU doing much in bee research? If so, who would the apiary contact be in wooster?

 

[hahnmeister]

The specs I gave ATB for the 4200 are HUGE. This pump can do 8000lph of air if you let it. 6" inside diameter, 2" thick, with 2" inlet and outlet. You are talking about a 1.5" diameter venturi as well.

 

[JCTewks]

that would be good for a saltwater swimming pool :lol:

 

[billyzbear]

I used the stock volute. I used the stock quick release too. I cut to the last one. Used a 1" slip and alittle electric tape to get a snug fit. I already had decided to go 1" anyway.

 

[dew2loud1]

hmm, the skimmer body will be 24" OD x probably 48" tall, I'm trying to replace a force fed dart....

I think this pump will still have to be forcefed, because in the two minutes I was messing with it, it didn't do well with restriction, but I'm sure a larger volute will help.

Hahn you're saying 6" ID volute x 2" thick, Do you use the stock impeller paddle or are you adding a larger disk to the old one?
