improved performance, improved reliability, and reduced life cycle costs. Most existing systems requiring flow control make use of bypass lines, throttling valves, or pump speed adjustments. The most efficient of these is pump speed con-trol. When a pump’s speed is reduced, less energy is imparted to the fluid and less
