Hello all-
New user here, i have had our pool for ten years but just now starting to take control of doing things my way! Looks like I will get great help here.
I just ordered a new Hayward EcoStar SP3400VSP pump to replace my old Northstar single speed. My existing pump is a 2 hp and the new one has a max HP of 2.75 (my understanding). I bought this particular pump on the advice of a Hayward tech, I emailed them my info and this is the pump they recommended.
My first concern is setting up the pump with the correct pump rpm's. I see from the manual that i can set the max rpm (the spec is 3450). I think I need to do this because I am concerned the power of this pump may be more that what is safe to run at 100% output. Per the Hayward manual, they recommend no more than 80 gpm with 2" plumbing. So I guess I should set the pump max so it does not go over this. There is where my question begins-
The Performance Data from Hayward on this pump is confusing to me because it relates all data to the Feet of Head in my pool. I have NO idea what this is for mine. Yes, I have read numerous articles about how to calculate this, but it really is a huge guess since I don't know the run lengths of my pipes, how many there are, etc. Below is the data from Hayward-
It obviously makes a huge difference what my resistance, feet of head is. Looks pretty clear to me that I should never run this pump at 100% capacity. Help please?
