Yes, I've cleaned the fan in the past.  The bearings look sealed to me, I've never lubed them.]]> Tue, 06 Jul 2004 06:35:00 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=2914&PID=28975&title=quieting-a-pump#28975 <![CDATA[Quieting a Pump : Did you try cleaning the fan housing...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=2914&PID=28971&title=quieting-a-pump#28971 Author: reptoreef

Did you try cleaning the fan housing and fan of all that dirt and lubing the fan? ]]> Mon, 05 Jul 2004 23:10:58 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=2914&PID=28971&title=quieting-a-pump#28971 <![CDATA[Quieting a Pump : I have an externalVelocity T4...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=2914&PID=28959&title=quieting-a-pump#28959 Author: jfinch

I have an external Velocity T4 pump for tank circulation and an Iwaki 40 that powers my skimmer.  I also have a Mak 4 that I keep as a spare.  The Velocity is unbelievably quiet.  Absolutely no sound.  The Iwaki (and the Mak 4) is a bit noisy.  The majority of the pump noise is caused by the motor cooling fan.  I was doing a little modifying of my skimmer and had the pump out from under the tank...  I thought, what the heck, I'll remove the motor fan from the pump making it quieter.  But rather then risk the Iwaki, I removed the fan from the Mak.  Here's some before and after pics.

Yes, I do know this is kind of a stupid thing to do .  I've got a quieter (separate external) fan blowing on the motor to help keep it cool.  The pump is quieter then before, not as quiet as the Velocity, but better.  It still has a bit of a vibration that I can hopefully kill with a little foam.

Have any of you done this before?  How did it turn out?  I will update this thread if the motor fails  or if six months down the road everything is ok .
