Do you have pressure/flow curves for either Intex or Bestway pumps? For either of these two, for example, 530 Gal Filter Pump (120v) - Pool Accessories - Above Ground Pools - Store - Default Category - Intex , Bestway ?
On another note, I see many pressure/flow curves that extend to zero flow - on Wayne's PC2 page for example. Most full size pool pumps have flow rates above 50 gpm. What will happen if I run a pool pump at low flow, e.g. 3 gpm, by restricting the outlet? This is equivalent to raising the water, as far as the pump is concerned. Will this burn out the pump? If so, then why do the manufacturers show curves extending to zero flow? If not, then why do the pumps technicians tell me (when I call them) that it will?
