Yes. Same pump, different driver and power brick. You can easily convert a MP20 to a MP40W or the other way.<a href=showthread.php?s=&postid=14734813#post14734813 target=_blank>Originally posted</a> by James77
2 were Gen1's, the 3rd was a Gen2. The noise didn't seem as pronounced on the Gen2- but still too loud for my liking.
Someone correct me if I am wrong, but isn't the MP20 the same pump as the MP40 with a slower driver?

Is it the same motor on both?
Unfortunately, no. I have not had the opportunity to try out the 6105. There have been noise issues with them reported on the Tunze forum. Supposedly, it goes away after a couple weeks when the pump breaks in. Tunze is making a change of a bigger prop and a lower voltage to run the pumps at a slower rpm to address this.<a href=showthread.php?s=&postid=14734866#post14734866 target=_blank>Originally posted</a> by James77
Scott- have you heard/tried the 6105's?

Damn, some good info here. Thanks a ton everyone. I am a bit concerned with the potential noise issue with Vortech. right now I am leaning towards sticking with Tunze. Thank you very, very much for all of the insight![]()

Great information here! I too am thinking about the Vortech pump but I was reading something about wavemaking in a tank will shorten tank life by 20%. I know that may not pertain to just Vortech or Tunze system but to all wave making systems. Would someone comment on that?
