The station was being retrofitted. The old pumps—reliable, brutish things from the seventies—were being swapped out for high-efficiency, variable-speed rotodynamic pumps. It was a delicate operation. The new pumps were sleek, powerful, and incredibly sensitive to bad manners.
ANSI/HI 9.8 is the definitive industry standard for the hydraulic design of pump intakes for rotodynamic (centrifugal, mixed-flow, and axial-flow) pumps. It provides critical guidance on preventing intake-related problems such as vortices, uneven flow distribution, air entrainment, and pre-swirl—conditions that lead to cavitation, vibration, reduced efficiency, and premature pump failure. ansi hi 9.8 rotodynamic pumps for pump intake design
