noizy return pump

[zeotz]

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?

have you tried rio hyperflow pumps? i think a rio HF 17 or 20 will suffice.

its quiet and has a really small dimension and low power consumption.

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.

thanks... so that could be the reason of my maxijet making hell lotsa noise.

Try eheim or aquabee. Both are extremely quiet pumps.

i agree I think the high head is causing the vibration and noize cuz if I let the pump run without any back pressure head, its super quiet.

will start a piggy bank to invest in a gd return pump

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.
