Centrifugal pumps for desalination
Desalination, 1981Abstract Centrifugal pumps used for desalination require more stringent material selections and different design considerations than normal applications. The liquid being pumped can be seawater, brackish water, or a concentrated brine. The longevity of the pumps in service depend on their design and the materials used as well as the operating ...

Publisher Summary This chapter discusses losses in efficiency of a centrifugal pump. The efficiency of a centrifugal pump naturally falls below 100% and it is the difference between the 100% figure and the actual efficiency that is referred to as the total loss. The total loss is made up of the following three major losses: power losses, head losses,

“Procuring” for this discussion means getting what is needed. For machinery such as centrifugal pumps, this usually involves four steps: 1. Deciding on the purchasing arrangement 2. Preparing the specification and bid request 3. Evaluating the bids and selecting the equipment 4. Placing the order and verifying

Vortex Pumps, or, Slip in the Centrifugal Pump
Proceedings of the Institution of Mechanical Engineers, 1939The current theory of the centrifugal pump does not correspond with its actual performance; it suggests a reserve of 30–50 per cent of pumping capacity available to the designer. The author questions the existence of this margin and examines the energy of rotating bodies of fluid.

Publisher Summary This chapter deals with centrifugal pump, which moves liquid by rotating one or more impellers inside a volute casing. The liquid is introduced through the casing inlet to the eye of the impeller, where it is picked up by the impeller vanes. The two pump types that are more commonly used are the American National Standards Institute (

Maintenance of Centrifugal Pumps
Journal AWWA, 1942response to duty of those charged with delivering an adequate and safe water supply to the public must necessarily include a sound policy and technique for the maintenance of all equipment, in addition to the customary provisions for standby. A poor maintenance program overworks standby equipment and will ultimately lead to trouble.
