aerosmyth,
I like your style - assume the harder the sell,the bigger the bull****. Good luck with the Viton seals. The Teflon seals are crap, IMHO. Viton is the way to go.
Cavitation of the water pump is an interesting possibility. Few people in the industrial pump business design a pump to behave predictably at variable RPM, especially such a huge range as 600 RPM to 6000 RPM. I would love to see some papers from the big 3 since they must have analyzed the hell out of this, but I am out of my depth dealing with this RPM range. George, most industrial pumps run at a fixed speed. A pump that runs happily at 600 RPM will tend to cavitate at 6000 RPM. I suppose you could deliberately use the performance drop associated with cavitation to reduce the HP demand at high RPM. Anyone know of any papers by OEM's on water pump design?
