Energy Efficient Pump Control

Energy Efficient Control of Pumps

A recent trend shows a significant push toward using variable frequency drives (VFDs) for improved pump efficiency, particularly when throttling valves have been used to control flow. However, there is increasing evidence that for many pumping applications where real-time flow control is not necessary, VFDs are not the most energy efficient solution.

Variable Frequency Drives on Booster Pumps

Pressure booster pumps will essentially add pressure to a facility’s water supply system at times when the water main’s pressure is not sufficient. Most industrial, commercial, and large facilities require pressure booster pumps to supply adequate pressure to water supply sources, maintaining a constant pressure throughout the entire facility.

Smart Motor Brake Stops Band Saw in Less Than a Minute

The Problem: Blade Wear with frequent replacement causing lost production time.

Operations needed to change the band saw blades several times daily. Before the blade could be replaced it needed to decelerate to a complete stop. This typically would take 30 minutes which resulted in costly down time, and costly replacement of the blades.
