VFD advice please for 2HP motor

[vas]

well,

we should know if it works and makes any difference in a week or so.
Trevor, once I get it in my hands and go through the manual, I'll PM you for instructions (or hopefully to give the OK to what I think I should do )

Yes, not too bothered if it does 1750 or 1700 as long as it doesnt do 1400something as the pump should be able to flow 20% more seawater through the membrane at around 1750.

cheers

Flow through the membranes is a function of pressure, temp and salinity. Not feed flow.

Following all the reading and discussions I've gone through, I have a feeling that this is not right.
A 2GPM and a 6GPM pump both capable of 800psi will most likely not produce the same amount of water through the same membrane.
Flow does have a role in this as demonstrated in the DOW manual when discussing recovering rates.

Anyhow, let's wait and see.
