energy efficiency

In the Solution to Pump Challenge #3, we touched on efficiency and energy savings by approximating energy costs. Can we do this more precisely?
Several years ago, a golf course community wanted to adorn its entrance with a waterfall.
In Pump Challenge #3 (Pumping Prescriptions, September 2009), the specified parameters for energy estimation were 4,000 gpm and 400 ft.
In Pump Challenge #4, many of you discovered while using the Energy Consumption Evaluator, that the standard listing only goes to 8x6-17 pump size with motor power maxed at 250 hp.
The economic downturn has delivered a heavy blow to the industrial manufacturing sector in North America. Manufacturers are indicating sales drops of 30 percent to nearly 60 percent compared to that of 2008.
As energy costs rise and energy efficiency becomes more important in operating pumping systems.
Back in the old days, level control had little or nothing to do with saving energy. In fact, it was often a necessary evil. Today, that is no longer true - the VFD offers the potential for power savings in lift station applications that range from a few hundred gallons per minute to those that have to move thousands of gallons each minute.
Maximize energy efficiency by identifying the pumps’ optimal flow rate and air consumption.
Determining which pumps and their associated systems to assess. pump system optimization, pump efficiency
The ever-growing need for energy efficiency demands intelligent pumping systems.
The Merchandise Mart in Chicago, Ill. is the world's largest commercial building, largest wholesale design center and a premier international business location. Encompassing 4.2 million gross square feet, the Mart spans two city blocks and stands 25 stories high. It welcomes more than three million visitors each year to its retail shops; boutiques; 11 floors of permanent showrooms for gift, residential, casual and contract furnishings; 10 floors of office space; dozens of trade shows and a myriad of special educational, community and consumer events. pump system optimization
Factors to consider when deciding the priority of pump efficiency.
When assessing the vast chemical industry, it is usually not advisable to deal in generalities.
Because operational costs ride on efficiency determinations, accurate measurements of losses occurring within the motor are paramount. The reliability of efficiency data is key to any energy-savings plan, and knowing the meaning behind the rating can make or break a smart purchasing decision.
While it is valid to state that energy efficiency is defined as the same level of production achieved at an overall lower energy cost, it is equally important for today's machine builders and automation engineers to remember an energy efficient system can actually translate into higher productivity. This is achievable through a comprehensive approach to energy management.
In the U.S. industrial sector, motor-driven systems consume 70 percent of all electricity. Motor-driven pumps account for more than 30 percent of that amount-more than any other application. Considering energy and maintenance represent more than 80 percent of total motor life cycle costs, a growing number of system designers, specifying engineers, maintenance professionals and end users are turning to variable speed motor control systems that can save up to 60 percent in energy costs as well as significantly reduce maintenance and equipment costs, improve process control and enhance system reliability.
A crucial triumvirate for improving the bottom line. pump system optimization, pump efficiency
Air-operated double-diaphragm pumps gain energy efficiency and reduce maintenance costs with innovative technology.
How does FSA’s role in standards development affect the pump and seal industries?
To achieve a sustainable future, the green movement demands increased energy efficiency and conservation. Here is a look at how these changes will impact the water industry and its use of pumps and controls.
