Do my pumps pass the pump efficiency test? This is one of the most important questions you will ask yourself as a pump operator. The answer to this question can either lead to opportunities for energy savings or lead to peace of mind knowing your systems are running optimally. A wise man once said, “And if you don’t know, now you know.” More specifically, you will know your next steps by the end of this article.
The purpose of a pump efficiency test is to determine opportunities for energy savings with your pumping system. According to the Department of Energy, a pump’s efficiency can degrade as much as 25% before replacement. When you consider other factors, these inefficiencies can add up quickly. For example, in the San Joaquin Valley, it is common for water movement in support of various processes to account for 60% or more of an agency’s entire energy portfolio. When the energy load is this substantial, it makes sense to cut costs wherever possible.
When a pump efficiency test is performed, more than just the pump is evaluated. It includes efficiency measurements of the entire system, which is often composed of one or more pumps, motors, and various other components. A pump efficiency specialist will use special instruments to measure head and flow rates. The potential for energy savings can be determined by calculating the difference between the actual operating efficiency and the design efficiency.
Many things can contribute to the inefficiency of a pumping system. The most common cause of pump inefficiency is worn or deteriorated components. A pump efficiency test can also determine operating adjustments that can be made to optimize various changes in electric rates throughout the day or by simply reducing operating times without compromising production.
Most people cannot do a pump test on their own; you need a pump specialist to assist with the calculations. This is why the Advanced Pump Efficiency Program (APEP) was developed in partnership with California State University, Fresno, and utilities to support customers. APEP has been operable for many years, and although the incentives have changed over that time, the program and its services remain consistent.
APEP provides a network of reputable contractors who are well-versed in the program's parameters. These contractors can be selected based on your location for PG&E, SoCal Edison, and Southern California Gas Company customers. SDG&E customers can address agriculture and industrial efficiency services, rebates, and incentives through the statewide programs offered uniformly statewide through the Water Infrastructure & Systems Efficiency (WISE) Program or the California Energy Design Assistance (CEDA) Program.
There are lots of resources available! The savings never stop.
