Oceanrunner needlewheel vs Sedra needlewheel

Needlewheelled 1260 sure produces one of the nastiest skimmate... But i not too sure but i doubt u can get one unless u have bought the skimmer...

According to finsreef, owner of www.finsreef.com you can buy one w/ out the skimmer but everything is in metric so you'll have to get creative w/ how you connect it to the skimmer housing, but shouldn't be a huge issue at all.

I have many 1260s and I know I can get just the intake and impeller...just wondering how they stack up compared to the sedra and OR...to me eheim makes the most silent and reliable pumps out there so as long as they make it, I might try to buy an ER-style filter and just run it off my own pump that I have already. As of next week I will have two 1260s laying around because they got upgraded to 1262s...

So are they better then the sedra and OC?
 
I've seen all of them in action... and I'd say the eheim is superior... however, I don't know by how much. I just know that the bubble density was really thick and the bubbles were small, but couldn't really tell you whether they were smaller or larger than the ones produced by the OR 3700 or Sedra 9000. The bubble density was thicker though.

Herbert,

I hope you get the intake and the impeller, but be warned that it might not work on your unmodded eheim 1260 pump. I'm not sure if it's true or not, but I definitely don't want you getting stuck w/ over a hundred dollars of stuff that you can't use in your unmodded pump. I think if you find that it does work, then that's great!

Peace,

Making a venturi that performs as well if not better then the Sedras is pretty simple.

Get two 3/4" X 1/2" reducers
Small piece of 1/2" PVC (Sch. 40)
small piece of 1/2" CPVC
one 1/4" threaded john guest coupler.

You can do it one or two different ways. The first way, take a short (maybe 1-1/2") piece of 1/2" PVC pipe. Just slip the pipe in to the 3/4" X 1/2" reducers. Then simply drill your hole and tap the 1/4" threads for the JG fitting. Then just install a piece of 1/4" tubing. If you want to be able to adjust the amount of air being taken in then use a 1/4" JG control valve insted of the straight fitting. This one works as well as the Sedra.

The other thing I did was the same as mentioned above EXCEPT I used my dremel and ground out the 1/2" piece of PVC then jamed a piece of 1/2" CPVC inside. The CPVC is smaller then normal sch 40 PVC and it makes the inside diameter a little smaller to squeeze the water in.

Here are some pics incase your confused.

This shows both reducers, piece of 1/2" PVC with a piece of 1/2" CPVC inside, and the tube connector. Very simple.

This is the assembled venturi.

Unless you are going to glue this to the pump I would only use this IN SUMP because like John mentioned the pump's inlet is metric and this fitting fits in very loose. Another option is, inside the intake of the Sedra, King, OR, and Gen-X pumps are 1" FIPT, you can make the same mod except using a male 1" connector then just reduce down to 1/2". Let me know if that sounded to confusing :D

oh, the impeller and intake are cheap...under $20...and as I said before I already have the pumps.

Where are you finding this H&S impeller and intake for under 20 bucks?

The intake costs 15 dollars and the impeller costs a whopping 110 dollars. Are we on the same page, because I don't think we're seeing eye to eye on this issue. What impeller are you going to put in those 1260s?

That's the only place in America that I know that sells them.

little late but, ocean runner 2700 has 18mm inlet & outlet...big PITA to do a reculating mod with one but I did it and it works great, soo much better then before...its also quiter then the sedra pump too
 
rufio173,
H&S isnt the only company that makes a needlewheel eheim...
Deltec, ER at one time (and still makes the part), and Aquamedic all make eheim 1260/1060 needlewheel impellers...there are prolly more...I remember seeing one that was not as expensive as the "Bentley Priced" H&S.

As for JDM's mod, why not just use 3/4" PVC and drill the 1/4" hole in the side for the air inlet with ridgid tubing? This works for me with most pumps...just not the MJ1200s...

I can not speak for the Deltec or the Aquamedic impellers, but The H&S needlewheels take a different impeller cover than what is on a regular Eheim 1260. Unfortunately they are not avail separately. The Aquamedic Impellers are listed for the 1060, and according to Eheim, it is a different application than the 1260 impeller. You do not need to own a skimmer to purchase the pumps, but the outputs are metric pvc and would have to be adapted. If you run a properly designed venturi, you will get the correct bubble size along with air intake to make the pump perform to optimum.

ER doesn't make the impellers for the 1260 nor can they, since they would be breaking some patent laws or some agreement.

Anyways, the Deltec impeller is just as expensive as the H&S ones... the last one I saw was around 80-90 Euros.

Aquamedic makes a needlewheel, but like I said before they are completely different needlewheels (bike spokes vs. pins). From what I can tell and from air values posted at least for the sedra 9000 (400ml/hr) vs eheim 1260 (600ml/hr). As for as I know, no one has posted numbers for the OR 3700, but my guess is that it is just a little more than the sedra 9000.

I do hope that you try some experiments and let everyone know which needlewheel impellers will work in the 1260.... especially if it is under 20 bucks (the standard impeller isn't even that cheap?). Still don't know where you came up w/ that number. Are you going to make a DIY NW impeller?

Thanks Brian for the clarifications.

Peace,

The H&S 1260 will pull~900lph of air when properly adjusted. The OR 3700 that was on my Turbo Shorty pulled~500lph. The Turboflotor Shorty does not have a decent venturi, and there is room for improvement there. If set up with a decent Venturi and have it with very little backpressure you should be able to get ~600lph+ out of the OR3700. Also the OR is a lot quiter than a Sedra.

I could be wrong HERE!
but an EHEIM 1260 is rate for 600GPH @ 0' head
while the OR 3700 is rated for 900 GPH @ 0' head
how come .........in this case is pulling more air than OR 3700?:o
 
John - Do you think it's really the needlewheels?

They are very similar to the sedra NW's.

I believe it's a combination of the venturi and the output of the pump with the directed flow piece in the impeller housing. I think that helps a ton with the pump efficiency.
 
Well ejamrshere,

The new beta ER pumps actually look far more similar to the H&S/deltec needlewheels now and they are pulling more air. Of course there have been other modifications, but I think proper configuration and arrangement of the needlewheels make a huge difference.

I think that people who have used both say that the actual pinwheels are better, although when I compared a sedra 9000 to an OR3700, I'd say the OR3700 came out on top. However, I've only seen a couple of eheim1260s on a deltec and it seemed to be doing a real good job, but those damn pumps are so expensive that I don't have the dough to really do a test, but the pumps are damn sturdy and real quiet.

Peace,
John H.
 
The new ER pumps also have the bit on the outlet inside of the impellar housing - That and they are 1100gph pumps.

still don't think in quality they are as good as the eheim....
 
Eric,

Not anywhere close... they are stinking submersible Gen-X pumps. The submersible line sucks big time, but their external pumps are awesome.

Peace,
John H.
 
I know they are gen-x:

http://reefcentral.com/forums/showthread.php?s=&threadid=557746&perpage=25&pagenumber=12

I was pretty sure it was the next step up in gph from a sedra 9000 to begin with... there is a wp pump that pushes around 1100gph so thats what I figured it was... could still be the same pump... then they opened up the 4100 thread about the metal plate and everything kind of fell together.

I'm not sure if the stock 4100 has the outlet flap, but the new beta pumps do. It's in that thread somewhere and you can kinda see it in the picture on that page. What you definitely can see is the L/hr rating which is 4100... surprise surprise.....
 
Yeah,

That outlet flap is quite the mystery. I don't know what that is for... I'd like to see the internals of the RD pumps. I don't think they have the flap, but I think the Eheim 1260s have them.

Peace,
John H.
