Sicce pumps

[hahnmeister]

True, when you look at BK deluxe and the new SWC sicce run skimmers, the bubble plate is off the bottom anyways by a bit, so putting the pump in this otherwise unused space is just plain efficient.

 

[pescadero]

yes, more efficient. and in addition to the low mount adding to efficiency, an internal pump eliminates some of the potential for leaks! running the cord out of the effluent pipe is a great idea -- another way to help decrease the risk of leaks for out-of-sump skimmers.

and to think ... i just built a skimmer that has union fittings for a pump on the outside. well, now i know what to do with the leftover pieces of 6-inch pipe! i guess i'm going to start a DIY skimmer collection!

 

[hahnmeister]

yeah, you can run the air hose and power cord through the standpipe... just make sure the standpipe is large enough to accomidate both these cords and its own flow! But the airline going up this pipe just makes sense, since you can put a muffler on the drainpipe, and so the airline would be completely invisible. The power cord as well is easy to do, and having a small notch coming out the top of the standpipe, well, easy enough to do.

Like so...

ostrow: Measure from the center of the output (or theimpeller, whichever is lower) on the pump to where the water level meets the foam head, that will be your total inches of head on the pump.

IME smaller dia, thicker meshmods tend to start better, while still producing as much air as a larger dia, thicker mesh.

Jeff, Jon, I'm wondering if you or anyone else who is familiar with the QO 3k can help me with a column height question:

I've got a 6-inch skimmer plumbed with 1-inch pipe for an external QO 3000 pump and a reduction-fitting type venturi patterened after your designs. The pump impeller hasn't been modded yet though modding it is an option. (I'd prefer a mod that provides absolutely reliable restarts over one that provides max airflow.) Right now the body is very tall (so tall that the venturis won't pull air if I fill the chamber with many feet of water) and needs to be cut down.

I'm trying to determine how tall of a water column a QK 3k can handle well. My preference is for a taller skimmer where I won't have to make lots of restrictions on inlet airflow; Instead of a short body that would require a lot of air inlet restriction, i'd prefer a taller body that would require less air inlet restriction. I'd like a taller body for the increased bubble path length. i'm not worried about compactness.

from a practical standpoint, how tall can you make a 6-inch skimmer that performs well if you're using a QO 3000 for the recirc pump? unfortunately i don't have an airflow meter yet, so at this point i'm still dependent upon the recommendations of others to determine how much bubble path length / head will work well. this skimmer will go into a water closet, and i'm not worried about fitting it under a tank stand.

thanks.

I've got a mesh modded QO 3000 on a 8" skimmer about 24" high. The highest I can get the water level is about 19". It stalls after that. Although it still pulls about 42 SCFH at that level. I'm working on a new pump (Maxflo) now and am hoping to get the water level higher.

jayson, I dont know how much air they are pulling on factory skimmers and I dont know whether you are comparing lpm to lph but it converts to 960lph.

nice post!!

 

[Jayson]

My numbers are in lpm. Thanks

Any idea where to get the ceramic impeller shafts for the psk2500 pumps?

i believe it's the same as the QO3000 or the QO4000 i test the 4000 and it's look the same one not sure 100% on the length .

 

[Bax]

I guess as long as it's not oo short I can trim it. I think I'll need a few of these, they break pretty easily when pulling the impeler.

... At least for me they do

 

[lecher]

The length of the shaft on the QO3000 and QO4000 pumps is shorter.

 

[Bax]

Thanks!

 

[ostrow]

Yes, I tried in a store. The QO shafts are not long enough.

 

[mavgi]

Bax:

ask Jayson i believe he sell them or reef geek .

 

[Bax]

Thanks guys ... glad I bought two!

 

[luke33]

You can generally go to a hobby lobby store and get a piece of ceramic shaft for a few bux, just cut it down to the right size and you'll have plenty to spare as well.

 

[Bax]

There's one near by, I'll try that first

I know folks are starting to favor the QO 4000 pumps but, I got a pair of Sicci 250 pumps a while back and finally modded one. I still have some starting issues with the mesh mod but if my test is a glimps of what these pumps have to offer, I am very happy.

Here's the modded imperler and volute

hey..
i would like to know where i can buy two SICCE impleros unmoded,without any mesh or moding..just 2 SICCE impelors..
if someone can buy them for me and send it to me in israel i can send hin the money with some extra cash for the trouble..

i would like to do the mod as shown in the picture above but i can get only MESHed SICCE impleros in israel..i belive that working the way shown in the picture above will be more affective.
thats why i need ywo stock SICCE impellors..

thank you.
matan.

Wanted to get your opinions on this:

Is it possible to put a Sicce on a EuroReef RS 135? Or would it be too much.

The chamber is 6", Height is 24". I'm only pulling 11lpm, and I'm looking for more air.
