Shutoff Pressure = P max. suction + 1.25*(∆P rated). b. Steam turbine driven pumps Est. Pump Shutoff Pressure = P max. suction + 1.38*(∆P rated) NOTE: The rated pump differential is based on pumped fluid maximum specific gravity. 6.4 Nozzles and Pressure casing Connections Paragraph 6.4.2.3, Addition Flange classes are specified in accordance with ASME B16.5. Flange classes listed in the UOP Project Specifications are based upon design pressure and temperature conditions only, and do not account for other loads.
