Pumping systems account for a significant portion of a facility's energy use in many industries. In the majority of pumping systems, energy added to the working fluid by the pump is much greater than required by the process.
System reliability and efficiency are major topics within the industrial sector, and they are key to achieving sustainable growth. Operating pumping systems reliably and efficiently requires optimum system control and protection.

With the current and pending retirement of experienced workers, who will take care of this critical equipment?
According to a Government Accountability Office (GAO) report issued in 2006, the percentage of workers over the age of 55 is projected to increase significantly during the next 20 years, with this particular demographic group projected to comprise as much as one-fifth of the nation's workforce by 2015.
A perfect storm appears to be developing within the industrial sector, and it seems to be growing across all industries.
In this particular case, we have multiple problems. On the upside, there are solutions.
Automated System Control The pump industry has successfully embraced the variable frequency drive (VFD), and the number of applications in which induction motors are fed by VFDs is growing quickly. Drive technology has stepped up to the plate to meet this growing demand and address—to some degree—the shrinking workforce.
Process control software is an effective solution for multiple pumps operating in parallel.
Each motor is started or stopped based on runtime, extending equipment life.
Process control software (PCS) can address the cycling of pumps. PCS is designed to reduce system operation and maintenance costs while increasing process accuracy and protection. The software provides pump control and protection, as well as system monitoring. PCS can be applied to any system that requires constant flow or pressure.
