Pumps used as hydroturbines offer economy and design flexibility
The need to move fluids from one place to another has created a vast universe of pumping equipment of various shapes, sizes, configurations, and designs. Describes how standard pumps, from radial flow to axial flow geometry, can be readily adapted as hydroturbines to generate up to 1500 kW. The range can be extended by using multiple pumps. Discussed are vertical propeller pump/turbines for wet pit applications; a vertical mixed flow pump/turbine at dam site installation; a horizontal split-case pump/turbine installed in parallel with a pipeline pressure reducing valve; a variable flow system with constant head utilizing a single constant speed turbine; a variable flow system with constant head utilizing multiple constant speed turbines; a multiple turbine installation serving as a pressure reducing system in a pipeline; a variable head system utilizing multiple 2-speed turbines; and multiple 2-speed turbines in a system with very steep head curve.
