Nov 08, 2007I thought of a possible solution along those lines that would operate all three pumps at variable speed at the same time. If I use the pump equations and scale the big pumps speed signal so that its shutoff head is about equal to the other two pumps and then let them ramp together, granted they won't have the same characteristic curves, but they should at least share the load such that no pump

Pump efficiency is the ratio of the liquid horsepower delivered by the pump and the brake horsepower delivered to the pump shaft. 100% efficiency is never realized because of mechanical and hydraulic losses incurred in the pump. The example curve shows the maximum efficiency for this pump to be in the 60 percents. The goal, of course,

The paper is focused on understanding the flow losses and the resulting flow/pressure dynamics in a piston pump. Initially, equations to evaluate leakages in all piston pump gaps will be presented and tested against numerical models, later the equations will be linked to determine the general pressure/flow pump dynamic characteristics.
