I'm attempting to put together a water supply system on my remote, off-the-grid property. Here's a sketch of what I have & would like to have:
<> a 100' artesian well that the driller found to have 15GPM flow rate (w/ the drill still at 100').
<> The water has moderately high Iron & Manganese and i'm planning on using a Filox filter
<> The well pump will need to lift from 60' down the well casing up to the top of a 2500 G storage tank that's 110' above the wellhead for a total lift of 170'. The tank is 1000' to the east so obviously there will be friction loses in the plumbing.
<> The storage tank will feed the (temporary) home - which is at wellhead level - by gravity feed. (Later on it will feed the not-yet-built permanent home which is much closer to the storage tank)
Because:
(a) I'm off-the-grid i'd like to have an energy-efficient pump. I don't need high GPM from the well pump because the storage tank outlet plumbing determines the delivery flow rate of the system. I currently use *very* little water - approx 10 -15 gal per day. (Yes, I know i'll start to waste water like normal Americans once I don't have to lug it by hand anymore)
(b) I think the performance of the Filox filter will be improved if I slow the flow through the filter to something closer to 1 GPM. (service flow rate spec is 3 GPM) The filter will be located close to the wellhead and the outlet of the filter will go uphill to the storage tank.
I was given a used Goulds 5GS10412 pump that has a dead Franklin 1HP, 230V motor. It appears that I can replace the dead motor w/ a new 1/2HP, 115V for less than $250. I took the Goulds pump apart and everything looks fine.
Ok, (at long last) here's my questions:
(1) The Goulds pump cylinder housing threads appear to have a gray residue on them which I assume is some sort of thread sealer. What should I use on the threads when I put this back together?
(2) The pump currently has way more flow & pressure than I need. (according to the current Goulds specs at 170' of head it can flow 7GPM w/ a 1/2 HP motor) Can I take the impellers out of say 1/2 of the stages and get enough flow to keep the motor cool (ie: 1 1/2 GPM) and reduce the current draw of the motor while still being able to lift 170'? Or is there a better way to do what I want to do?
