Well here it goes guys .
Mine is a very simple system there lots of other ways to build a water maker .
You can add all types of complicated stuff .
But as frankly said , "I did it my way "
I used a cat 277 pump driven by a 1.5hp motor .
You can also run these cat pumps of your engine A combination of pully and belt .probably a better way ,then you won't need a Generator to run the motor .
Parts needed
Cat277 or 247 pump , castle pumps in Nottingham
Pressure vessel 40x2.5 tested over 1000psi I used a fiberglass one .....allwatertech.co.uk
40 ins Membrane . desalt U.K.
2 sea cock .... chandlers
1 sea water mesh type filter ....chandlers
2 water filter contains ...eBay
1 jabsco puppy pump .... chandlers
2 water filters 1x 10 micro 1x5 micro ...eBay
2x 2 way valve SS ..... plumbers
1 pressure water valve......eBay
1 pressure. Vacuum Gauge glycerin-filled .......eBay
HP pipe and connection . hydraulic company .
Good quality water pipe .. diy
SS fitting .
Hose clips ....diy
Odd and ends
As you can see by my bad drawing .( nearly as good as my writing )
Sea water flow first through a wire filter then the puppy pump before entering a two way valve ,
The two way valve has a second pipe which comes from the water tank .
The third pipe which at different times carry both sea water and fresh product.Water goes to first the 10 micro filter then the 5 micro filter .
From there there go to the HP pump , in this case a cat 277.
Are you still with me ?
Up to this point you can use any good quality pipe , I used the reinforced type .
From this point you going to need HP pipe with SS fitting , I had all these made up at a company that made pipe from diggers and cranes .
HP pipe then goes into the bottom end of the HP vessel which houses the membrane,
Also at the bottom of the vessel there another fitting , this will carry your fresh water . A pipe is lead to my tank it also goes through a 2 way valve , this is where I can test the water before filling the tanks
The top of the vessel is fitted with a pressure valve and a vacuum gauge , a pipe is lead from the pressure valve which carries the brine water back out side .
Using this system I can get s much as 80/90 LPH depending on water temperature.
My TDS so far after 15 months used is 120 , you can buy a cheap TDS meters off eBay .
You will notice that the black HP pipe goes around it self a few times , this stop a lot of the vibrations, although you can buy a valve to help with the vibrations but there about 140 pounds .
I also wrap foam in leather around the HP pipe to stop it rubbing on it self .
I know one person who used a pressure washer pump , off is inverter and he says it works find , but he has to replace it some time twice a season .
I still yet to give it a try in case my Gen stop working .
Problem with pressure washer pump is they not made to work non stop .
I hoped I cover every thing , no doubts I be editing it when I find my spelling mistake .
Lots of stuff on the internet if you can't understand my drawing .
How much did it cost ? About £1000 give or take a few pounds , the cat pump is what cost the most .
