RE: Low NPSHa brine pump
RE: Low NPSHa brine pump
During the preliminary layout design phase of the facility, the very low NPSHa should have been evaluated.....why was this not considered earlier ?
You can find "low NPSHa" pumps advertised.....but as I recall, the NPSH that they require is about 5 feet....
All NPSHr quoted by pump vendors are in terms of "feet of water"....if your process liquid has a significantly different density that water, you must adjust
My thoughts only.....

Luckily, some pumps out there work well with 1 to 2 feet of NPSH. Thus just worked around the cost and now we are ordering a reasoanbly priced one.
Thanks to all for the feedback.
