Tellie, Thank you for your critique, I appreciate it.
I assume, from what you say, that you can run the system at the lowest pressure that produces a reasonable fresh water flow?
I am aware this is a hands on unit which is why it is larger than most, and will only be operated once a week, when I can produce a weeks supply of fresh water, and the flushing
etc in fresh water is only once a week.
Foggysail, the gasoline motor
and pressure pump came as one unit.(pressure washer)
It has an output of 3 gallons a minute, which is needed for sufficient flow through my membranes. The maximum pressure is rated at 3,500psi but I only intend to use what i need to produce fresh water.
It has a brass pump and came with a spare set of seals
I do not know yet what the flow rate will be at 700psi but I am advised it should be at least 3 gallons a minute or more, but that can all be contolled by the motor
throttle and the pressure regulator?
A don't think a flow of more than 3 gallons a minute should be a problem anyway, as long as I control the pressure?
