  • Great! With a little work... By Elliott on 4/4/2014

    This is a great little pump if you're willing to put a little effort into making it silent. When I got mine, I hooked it up, and while it is relatively quiet, it wasn't quite what I expected from such a big name. I do a lot of work for my employer on pumps significantly larger, so I felt perfectly comfortable cracking it open. They're a really simple design, and similar to 99% of electric motors out there. What I found was the bearings the pump came with (6200Z) didn't have any lubrication in them, and were the major contributor to the noise as the balls rattled around in their races. I pulled those off and went with a double sealed 6200zz bearing. I'm not sure if the originals had lube in them when they were installed or not, but with the new ones in there, the motor barely hums as it works. Once hooked up to the pump, and supplied with water, it can't be heard outside of its stand. (I do have it mounted on rubber motor feet and plumbed with spa-flex). Even though it took a little extra effort, it's a great pump and now should last even longer than a stock one.
  • There's better choices By Not worth it on 3/6/2013

    Got this because my md-20 iwaki was quiet and this one was super loud. Sent it back and didn't hear back for weeks. It took over a month to get one back so I had to get a different pump from someone else. So the good news is the reeflo blowhole is cheaper and way more quiet.
  • Great Pump By gmastr85 on 1/6/2013

    I use this pump on my saltwater mixing station. Typically I run the pump for 24 hours or so, once or twice a week. It's worked wonderfully so far and I've had no performance issues with it. It is not completely silent, but I have it running in my furnace rooms so I don't hear it. The only complaint I have, is that I had to go to Lowe's and purchase a AC plug and wirenuts to attach the power wires. It comes with the 3 wires coming from the pump and you have to wire the pump yourself. Not a big deal but remember you will spend a couple extra dollars and some time wiring this pump. Overall I would purchase it again, as Iwaki pumps have an excellent reputation.
  • Best pump I've ever had By Greg on 11/18/2012

    Pump runs quietly and dependably. No fan on this size, so the housing is pretty hot, but doesn't transfer heat to the water which is important to me. Iwaki is the only brand of external pump I would trust.
