Critical Considerations on Cavitation Limits of Centrifugal and Axial-Flow Pumps

Abstract This is the presentation of a problem, not of its solution. A critical examination of the cavitation problem of centrifugal and axial-flow pumps indicates that such pumps are operated at higher speeds than reasonably can be expected to exclude cavitation or local pressures below the vapor pressure of the fluid pumped. This fact is revealed by relating the over-all cavitation characteristics of pumps for which empirically determined values are available to detail characteristics usually described as blade-pressure coefficients which are sufficiently backed by empirical and theoretical information to permit rational interpretation and an estimate of future developments, including pump operation with fully developed cavitation.

Some Aspects of High-Suction Specific-Speed Pump Inducers

Abstract Some aspects of the design and performance characteristics of high-suction specific-speed pumps (cavitating inducer) are discussed. Although conventional pump-suction specific speeds are limited by incipient cavitation limits, the properly designed cavitating inducer can operate at values of suction specific speeds many times that limited by incipient cavitation. Owing to the restricted nature of this material, the authors regret leaving out much of the design information.
