Any bros can help recommend a quiet return pump in sump (8.5" width) for my 30G tank. Flowrate around 2200~3000l/hr wud b great.

i have tried weipro, jebao, hailea ... all fail.

for the jebao, I am currently tilting it with one suction pump resting on my skimmer pump. Only in this position it can operate silently.

Are there self priming external pumps around?

hmmm .. mayb i loan one and try first.

cuz in another forum, rio pumps were remarked to be noizy sometimes and also prone to breakage.

I know if I get the aquabee, sure no noize (cuz the skimmer pump is aquabee and anywhere I put it also no noize at all) ... but quite X.

The noise you are experiencing is due to the back pressure created by high head that most Asian-made pumps cannot handle.

This causes them them vibrate and in the long run, looses its effeciency.

Some pumps will also generate high heat when put in a high head environment.

To me, the return pump is quite important and I will not play around with it.

I am currently using Aquabee 3000. I believe Acidjazz is selling his brand new one at a super price of $155.

You may one to contact him. ;)

guys,

I jus bought a sicce multi 4000 pump (made in italy) and still hav the same problem. If I tilt it, the noize is less. if I put it near the sump wall, the noize is terrible. If I run it without head, its super quiet.

I am pumping it thru the chiller up to the main tank via 3/4" tubes and pipes.the noize definitely comes from the pump and not the pipes or anywhere else.

anyone knows of any technique that cna quieten this noize? I believe its not the pump, but mayb the piping configuration.

solution found by having a separate pump for chiller and return to main tank. my small sump now super crowded with 3 pumps.

I still wonder if a good pump can be used thru the chiller before returning to main tank without the noize.
