Adjustable Speed Pumping Applications for Reduced Energy Consumption

When exploring and learning about pumping systems, I was amazed at the information available online today in 2021.  For a non-engineer, there are numerous sites that provide incredibly easy to read and understand information.  The U.S. department of energy has done an excellent job with their tear sheets.  I’ve provided the information that they teach, as it’s an incredibly reliable resource:

Most pumps operating today were selected to meet a maximum system demand, or potential future demands. This means that most pumps are oversized, rarely operating at their full design capacity. In addition, pumps are often installed in systems with multiple operating points that coincide with process requirements.  A throttling valve is usually employed when the process flow requirement is less than the flow at the pumping system’s natural operating point.

How to Conduct an In-Plant Pumping System Survey to Reduce Energy Consumption?

In the United States, more than 2.4 million pumps, which consume more than 142 billion kWh annually, are used in industrial manufacturing processes. At an electricity cost of 5 cents per kWh, energy used for fluids transport costs more than $7.1 billion per year. Even one pump can consume substantial energy. A continuously operated centrifugal pump driven by a fully loaded 100-horsepower motor requires 726,000 kWh per year. This costs more than $36,000, assuming average electricity costs of 5 cents per kWh. Even a 10% reduction in operating costs saves $3,600 per year. Table 1 summarizes the electrical costs of operating this pump.
