J-Dog Posted June 29, 2011 Share Posted June 29, 2011 I just purchased a Maxi-Jet 1200 for my dual reactor, but when I place it in my tanks rear chamber, it makes a horribly loud vibrating noise. Is there any way to reduce the noise level on these pumps or are the 1200's just loud? I'm not sure if it's loud because it's vibrating against the glass or not. Just thought u guys would have some ideas since they are very popular pumps. Link to comment Share on other sites More sharing options...
impur Posted June 29, 2011 Share Posted June 29, 2011 They are not usually loud when new. I would also guess its up against something and vibrating. I wrapped a large rubberband around one of my maxijets that i use to mix kalk with because it rests against the glass and vibrates. You could also put a suction cup on the glass where the MJ is touching it. Link to comment Share on other sites More sharing options...

jonas Posted June 30, 2011 Share Posted June 30, 2011 I would think so. Just rubber and fabric. But I don't know for sure. Link to comment Share on other sites More sharing options...
impur Posted June 30, 2011 Share Posted June 30, 2011 yep i've used them under pumps plenty of times. Link to comment Share on other sites More sharing options...
Reefer503 Posted June 30, 2011 Share Posted June 30, 2011 With my pump (Quiet One 9000), if you just have it sitting on the bottom of the sump, it will vibrate the acrylic and make a little noise. I'm just going to pick up some heavy rubber washers from the hardware store and bolt/glue them to the pump feet to dampen the vibrations carried to the sump. Just another idea...

J-Dog Posted June 30, 2011 Author Share Posted June 30, 2011 Well, I just found out that the pump isn't the problem, it's the restriction gauge attached to the reactor. When I turn it down to have less flow so the media doesn't tumble too much, it causes the pump to become very loud. When I open the gauge all the way, the pump is quiet. So I guess I'm stuck with a loud pump, unless u guys know a way to solve this problem Link to comment Share on other sites More sharing options...

J-Dog Posted June 30, 2011 Author Share Posted June 30, 2011 Smaller pump? The 1200 was the pump that BRS said to use for there reactors Link to comment Share on other sites More sharing options...
impur Posted June 30, 2011 Share Posted June 30, 2011 Well if you have to dial it back then a MJ600 or MJ900 should work just as well. The only thing different is the size of the impeller. Link to comment Share on other sites More sharing options...
Bicyclebill Posted June 30, 2011 Share Posted June 30, 2011 Make sure the housing is fully engaged on the pump body, and not off one of the tabs. These pumps are typically completely silent. Perhaps running more media in each chamber will do the trick rather than throttling pump down too far. Link to comment Share on other sites More sharing options...
J-Dog Posted June 30, 2011 Author Share Posted June 30, 2011 I will ask the guys at BRS what they think. I'll let u know what they say Link to comment Share on other sites More sharing options...
