As a "self professed" DIY'er I certainly have learned alot from this forum and especially Valveman.
I have one of his awesome CSV2W's and have read much of the info on the site-impressive.
Being that the CSV has outlived 2 pumps in 12 years( 1st 11yrs and 2nd 1yr) I have spent probably 30 hours reading this forum, CSV's site and Pump Mfgs sites.
I have run into a problem......
Given that the CSV should not see a max pressure exceeding 175 psi and to reduce amperage draw with flow-you need a stacked impeller to do this.
Most every pump design is converted to a Floating stack impeller which can actually increase amps as flow is reduced-not good as more KW are consumed to produce less flow and higher shut off PSI's than Grundfos' fixed stack.
As far as I can tell, excluding generic Mfgs-Grundfos is the only Pump I can find that uses a fixed stack.
Anyone know of any pump makers that use a fixed stack impeller besides Grundfos? I am looking at a 15Gpm 1.5HP 2 wire 230W Franklin J/V or Schaefer legend/V(specs look identical) but these run floating stacks. I can go with the Grundfos but the cost is 2x.
I need to stay below 125 Shut Off PSI as I do not want to damage the CSV...Any Franklin powered pumps with Fixed stacks?
Thanks....
