Bill Schertz and I did some work with the stock pump and found that 53

gallons

was generally a very good output with the stock pump. Vance built a pump

dyno

and we found that about 2 HP was required to drive the stock pump. The

valve

simulates the pressure drop through a heat exchanger. I am still working

on

measuring the actual pressure drops throughout a real system. Your data

and

our data is tracking pretty good so far.

Paul,
Was that with a standard or bigger pulley.
TIA
George (down under)

As I recall it was large pulley on the electric motor with 6000 or 7000 pump RPM.
I can look it up if you need the exact numbers. You can too if you
have saved everything by using the search engine in your email program.
