I'm looking at building a new water
maker and I am looking at the Cat 3CP1221 high pressure pump
. The water
maker will be be direct connected to a 2.9 HP single
phase 220 volt 50/60hz electrical motor
is rated at 4.2 gallons per minute - but that will surely not be the output of fresh desalinated water. I know that the production of fresh water is also influenced by the intake water temperature. The electrical motor
will also run about 20% faster on 60hz than on 50hz - thus producing more freshwater.
I have some questions;
1. To reduce a large number of membranes, I am keen on 8" x 40" membranes. But how many of these would I need?
2. Operating at 50 hz and 80 bar, can anybody give me a clue (more or less) how much fresh water we can expect this pump to produce?
