  1. Great little pump 5 Star Review

    Posted by on 18th Feb 2018

    I bought this unit over a year ago. It has been watering cows hooked to a pressure system ever since and working great. My only complaint is the controller doesn't hook to a normal pressure switch.

  2. Excellent service, technical help and pump. 5 Star Review

    Posted by on 12th Oct 2015

    My system was a pleasure to hook. I especially appreciated that a controller came with the package. The pump is supposed to max out at 5 GPM but I am getting 5 1/2 at ground level, which is 47 feet above the pump. At 140 feet of total head (above the pump) to my storage tanks it was supposed to deliver 1.97 but am getting 3. A complete surprise to be so very satisfied in these times of doubtful manufacturer reliability. The technical department was always on call to handle my queries and the informative help given was "right on." Thanks for a great product.

    Solar panel used: 1 x 285 Watt, Vpmax =35.8V, Ipmax=7.95 amps.
