  • Strong pump By A on 7/15/2014

    Strong little pump with a perfectly sized fan. My pump has been running basically nonstop for over 18 months now. I have this pump pushing water up about 8' and through about 30' of pipe. It is also running a biopellet reactor and a GFO/carbon setup. The remaining water then goes through a small SCWD. I have never measured the output but it seems to work as a return for my 40. When I upgrade to a 75 I intend to use the same pump minus the SCWD. It draws about .7 amps according to my kill-a-watt, so pretty good for what I am asking of it. The output vibration does need to be isolated. I replaced the hard line I had coming out with a 1" vinyl tube for about 2 feet.
  • Nice pump a little loud By Aaron on 4/20/2014

    The pump fits my application perfectly. It's installed on my basement sump. I was really impressed with the flow rate as I made some unanticipated plumbing changes and still had plenty of flow.

    The one downside is it makes more noise than anticipated. I didn't use any flexible piping in my system so some of the noise is from the vibration through the hard pvc piping. I will be trying to break the piping to get rid of some of the noise. Also plan on changing the mounting of the pump all in an effort to change the noise. The pump right now can be heard on the first floor, so I will be spending sometime to get some of the noise out of the system.
