2 Simple Steps to Choosing the Right Motor

Pumps & Systems, June 2015, by Mike Stockman.
http://www.pumpsandsystems.com/motors/june-2015-2-simple-steps-choosing-right-motor

"Every pump industry professional faces the challenge of choosing the most efficient system for a particular application. This process is complicated by the uncertainties of efficiency regulations, mandates and parameters, especially when efficiencies alone do not tell the whole story. Sometimes the most efficient motor is not the best choice. By using two simple calculations, pumping professionals can determine the best motor—as well as the best pump and drive—for each application."

Developing a Pump System Assessment with Energy Cost Balance Sheets

Engineered Software, Inc., May 2015.
http://eng-software.com/company/press/2015/5/developing-a-pump-system-assessment-with-energy-cost-balance-sheets/

"The first step in the assessment involves developing an Energy Cost Balance Sheet for the way the system is currently operating.  We can then identify system improvement alternatives and develop an Energy Cost Balance Sheet for each proposed alternative.  These results provide the plant’s financial management team with the data needed to develop a course of action based on the potential risk/ reward."

A Financial Justification for Pumped System Improvements

Engineered Software, Inc., Feb. 2015.
http://eng-software.com/newsbrief/2015/2/financial_justification/

"This month we will look at the value of starting a proactive Pumped System Improvement program in which major pumped systems are evaluated on an ongoing basis. Prior to starting any new program there must be financial justification; this article shows how using readily available plant production data."

A Different Approach to Understanding Power Factor (Last of Three Parts)

Pumps & Systems, Nov. 2014, by Joe Evans.

"Two methods can be used to improve PF with capacitors. Static correction involves using capacitors to correct a single load. They can be installed at several locations. Static correction can be the most effective method, but it can also be the most expensive. Bulk correction uses a bank of capacitors that improve PF for different parts of a facility. These capacitors can be switched in and out of the circuit depending on the monitored PF."

"From setting up node addresses to the nuances of lead and lag pump operation, explore the opportunities for tailored, more efficient performance and increased redundancy."

Evaluating Farm Slurry Extends Life & Performance [Pumps]

Pumps & Systems, Sept. 2014, by Paul Davies.
http://www.pump-zone.com/pumps/september-2014-evaluating-farm-slurry-extends-life-performance-0

"Pump manufacturers know that the engineering phrase “fit and forget” never holds true for rotating equipment. For all its reliability and longevity, a slurry pump that has been operating in a pit for several years will eventually fail. Several pumps can handle farming applications at a tenth of the initial cost for an application-specific slurry pump. However, replacing a cheaper, less effective pump every six months becomes a tiresome—and expensive—hassle for many farmers. This article features several examples of how selecting the right pump ensured worry-free operation in harsh pit service."

Pre-Screening Unlocks Savings Potential in Large Pump Systems

Pumps & Systems, Sep. 2014, by Ray Hardee.
http://www.pump-zone.com/pumps/september-2014-pre-screening-unlocks-savings-potential-large-pump-systems

"When facilities—whether paper mills, refineries, or chemical or waste treatment plants—decide to implement pump system improvements, the first question is always the same: Where to begin? This month’s column looks at the pre-screening process, when plant management teams decide which system to tackle first. The pre-screening process quickly identifies which pump system has a high probability of improving plant operations, reducing total cost and increasing system uptime."

Customized Pumping System Brings New Efficiencies to Mineral Processing

Maintenance Technology, Aug. 2014, by Grundfos Engineered Systems (GES) team.
http://www.maintenancetechnology.com/2014/08/customized-pumping-system-brings-new-efficiencies-mineral-processing/

"Energy-efficient pumps, intelligent pump-control logic and variable-frequency drives help the company process more minerals and cut energy use."

Evaluating Power-Demand Reduction With VFD-Controlled Systems

Heating, Piping, Air Conditioning, Aug. 2014, by Alexander L. Burd and Galina S. Burd.
