I have a Goulds 33GS pump with a Franklin 5 HP 3 phase motor that was installed in my well (static water at 240 ft, pump at 367 ft, 5000 gal pressure tank, on at 30 off at 50, want apx 35 gpm) with new 2" galvanized pipe and wiring in 1997. I was working near the well site one day recently and noticed that the pump kept running the entire 60 minutes that I was there even though I knew no irrigation was taking place.
I removed the pipe from the pressure tank and installed a 2" tee with a pressure guage on one leg and a 2" ball valve on the other. I opened the ball valve and started the pump. Using a crude fill up 5 gallon buckets while checking my watch system i guestimate the flow out of the open pipe to be 25 - 30 gpm. When i closed the valve the pressure seemed to rise way to slow given the small volume of the pipe, and would not build over 50 psi. This pump is supposed to supply 37 gpm @ 50psi. So... I am thinking I have a pump problem.
I can call up Grainger and get a similiar Dayton pump (according to the production chart at least) and Franklin motor delivered to my door on open account in 2-3 days for about 20% less than an identical replacement goulds unit that i have to send payment for, then wait 5-7 days, then drive 40 miles into town to pick up.
Despite my whinning, the efficiency and long term reliability of the system is far more important than the small cost difference or the inconvenience involved in procurring the Goulds unit.
What would the informed recommend?
Thanks
