  • My Iwakis ran for about 15 years By Gary on 10/12/2014

    I have two of these. One I bought 2 years ago and I just bought another one for a different application. Both pumps replaced older Iwaki American motor pumps that ran 13 and 15 years. I switched to Japanese because they are supposed to be even better. I can't remember when I had a different brand pump. As the website video says, the Japanese motors seem a little quieter than the American motors but both are of exceptional quality in my opinion. In the 15 years I had the American versions running (one for the skimmer, one for the return, I think I replaced an impeller once because it broke--something got into it; A different time I had a problem with calcium build up.(rookie move--Not properly maintaining Mg levels--I cleaned it and it was fine). I can't believe how long these pumps lasted. The one I just replaced was still working but was making noises and was very rusty--spilling/splashing salt water onto over the years and just being in the moist environment. I highly recommend these pumps. Gary.
  • Great pump, should have bought this in the first place! By Charles on 9/29/2013

    Replaced a loud power hungry pump with this one. Although this pump is rated at a lower flow than the old pump, the performance I'm seeing is equal or greater to the old pump. I replaced the old pump due to it's noise level. The pumps performance was constant, but the noise was getting worse and worse (loud humming that was there from the start). After installing the Iwaki, I'm seeing the power draw of the tank reduced by a 3rd even with the heater running more often, water temp is down by a degree, and now all I hear is the faint sound of the water moving through the system. If you can afford it, don't waste your money and your time, buy the Iwaki!
  • Good Pump By Warren on 4/23/2013

    Good pump but is a little loud. Was trying to find a quieter pump then my submergable, but this pump may even be louder. Going to try a little sound deading material. Even have the pump suspended in air so it's the pump and not the vibration.
  • Fantastic By Susan on 11/29/2012

    I really like this pump. I have never had an external pump before and I wasn't sure how loud it would be. I have been very happy with the performance and don't think it's too loud (my tank is in my dining room and the pump is not inside the stand).
  • Good pump By mgarc on 10/22/2012

    This pump is a real workhorse, never fails
  • Iwaki MD-40RXT 1200 GPH Pump By Doel on 9/14/2012

    Good pump it moves quite a bit of water in my 125. It's still runs loud, but all in all it's a good pump.
