Abstract:

The study was primarily concerned with development of an efficient pump handling silt-clay-water mixtures. One phase of the study involved recommendations for design changes of the dredge pump, involving modifications in the volute and the impeller. In another phase of the study, model investigation of four differently modified impellers was performed with water as well as silt-clay-water mixtures. The variables included discharge 0-1200 gallons per minute, speed 1150 to 1900 revolutions per minute, and liquid density 1000 to 1380 grams per liter. Analysis of the data indicates that certain modifications in the exit angle and vane shape of the impeller result in a marked increase in pump efficiency. Relationships between various parameters was established for all pump impellers investigated. Author
