Looking for confirmation on an NPSHa calculation involving a centrifugal pumping from vacuum vessel.
Fluid: Water @ 180 DegF
Fluid Density: 0.970
Vapor Pressure @ 180 DegF: 7.51 PSIA
Vessel: 28 in Hg Vacuum
Approx Friction Losses: 0.5 ft
Water Operational level above pump centerline: +7.5 ft
I'm looking for a solution for tagging our wastewater piping systems which get broken down prior to shipping and then re-assembled in the field.
I envision using some sort of metallic or plastic embossed tags which can be mechanically attached using tie-wraps or similar. Each tag for mating...
Looking for alternative vendors for ANSI style centrifugal pumps with wetted parts made from polyproperlyne and/or PVDF.
Conditions currently are for ~650 GPM @ 100 FT of head with low NPSHR, but we have many applications that range upto this flow rate.
Any have any reccomendations or success...
