Phosban reactor 150 help needed

[KJHawley]

I just installed a Phosban 150 from BRS in order to run GFO.

Based on suggestions I saw in various threads, I got a Maxijet 600 to run it - its rated flow rate of 160 gph is right in the middle of the recommended 100-250 gph for the Phosban 150. The instructions say that you can use the included ball valve to reduce the flow as necessary.

From what I understand, GFO should be barely tumbling. My problem is that when I reduce the flow low enough, the Maxijet starts buzzing like CRAZY (as in I can hear it from several rooms away). So, I can either open up the ball valve enough so that the pump isn't buzzing, in which case the GFO is getting pulverized), or I can lower to the right amount & not be able to hear myself think.

Other than just getting a different pump w/ lower flow, can anyone recommend a fix for this? Is my Maxijet just bad?

If you got the marine land maxijet, they do tend to buzz. The cobalt mj series would be a better option. They are quieter

Other option would be to shorten the pipe from the pump to the reactor intake, so that the pump is just hanging from the reactor and not resting on the bottom of the sump. I think that might help you deal with the noise without having to change pumps

If you do end up changing I would say pick up the cobalt mj1200. It's overrated flow wide but you can dial it down via the ball value and in the future of you want additional reactors you can chain link more phosban 150s and can stil use the same pump. No need to upgrade
