Mfg gives npsh requirements on the pump curve, yes. If the water was at 1.0SG and 70°F, I would be fine. Well within required NPSH. When water temp is 180°F though...
I was able to convert everything into absolute pressure and figure out what my static inlet pressure would be, then cross...
I have a graph of vapor pressure of water and temps. I know that the water going into this pump won't exceed 180F during normal operation. Water will boil at 180F at about 9PSIA (or so my graph says). Mfg cannot tell me what pressure my pump inlet will be at during operation with a 6ft suction...
Can a self-priming pump in a sump application (ie 6ft of suction lift and 20ft of discharge head) handle hot water? I know that as pressure decreases, boiling point of water drops as well. What do I need to know to figure out at what temperature my pump will boil the water it is lifting (and...
