I'm rebuilding a watermaker
from second hand parts
found here and there ...
My HP pump
is the Cat 277 model, drived by a 220V triphase engine
of 1.1kw. Pulleys ratio is ok to run the pump
at 1400rpm when the electrical motor
is at nominal rpm
But i have the masterpuppy 12v pump as low pressure pump. I've read here on the forum that this pump is not ideal for this application, and so I'm asking an experienced advice
by experimented users to make the good purchase!
Which kind of pump do you recommend, brand, quality, models, type ?
If i'm correct the feeding flow should be a little bit more than the Hp pump flow rate , so i guess more than 3.5 gpm (flow of the cat 277 at 1420rpm)
Thanks for your precious help.
