Last month’s column discussed the pre-screening process that identifies and prioritizes systems with a high probability of significant energy savings. After this process is complete, the actual...
Second of Three Parts
This series discusses the control elements of a piping system, which improve the quality of the product. Part 1 (Pumps & Systems, July 2015) covered passive controls, such as overflow and bypass...
I received a lot of feedback on my column “How Much Energy Do Pipes Remove?” in the September issue of Pumps & Systems. This column described the use of two computer programs that evaluate the...
Different material and design combinations offer application-specific advantages.
Design of the pump inlet piping can protect overall operation.
Piping plans for mechanical seals are used to improve the environmental conditions around a seal, extend its capabilities and allow operators to monitor seal performance. American Petroleum Institute...
My last column (Pumps & Systems, April 2014) explained why resistance in implementing pump system improvement programs often occurs. Because pump systems touch many disciplines and departments within...
Previous articles in this series explained how oversized piping systems can have higher operating and maintenance costs. Higher maintenance costs can adversely affect the reliability and uptime of...
Harrington Industrial Plastics announced the acquisition of ProTec Construction Services & Supply.“Harrington’s commitment to excellence and growth has never been stronger, which is why...
Correctly selecting and installing the ideal component provides significant health, environmental and economic benefits.
Last of Two Parts In Part One of this series (Pumps & Systems, February 2014), the operating and maintenance costs for pumped systems were isolated. The next steps are to set realistic goals for...
First of two parts. Read part 2 here. Prior to starting any new program, financial justification must be made. This column explains how to justify projects using readily available plant production...
Because pump systems can be complex, determining the root cause of problems in an operating system can often lead to a hit-and-miss approach that is time consuming and costly. For six years, that was...
What are the best practices for ensuring the reliability of API Piping Plan 53B?
Hydraulic Institute Pump FAQs February 2007
Pumps and Systems, February 2007Q. We are operating a large axial split case pump which occasionally operates at about ten percent of its best efficiency rate of flow. At that rate of flow, the pump...
If any silver linings exist for the economic crisis that has gripped the United States since last summer, one is the heightened public and governmental awareness about the nation's need for...
About 900 years before Newton formulated his universal gravitational theory, the Greek philosopher Aristotle espoused something different. He believed that all things had a natural place in the...
Pumps and Systems in Transcontinental Energy Transfer
Massive amounts of energy are used to transfer oil and refined products over long distances. In the United States, several long distance pipelines move gasoline from the refineries in the Southwest to...
Energy Savings with the Correct Duty Point
 With continuously increasing energy costs, pump manufacturers must provide energy efficient solutions for fluid transfer. Besides hydraulically optimizing current technology, manufacturers are...
Click here for solution to Pump Challenge #4Consider a typical ANSI-dimensioned 1x1.5-6 pump, as discussed in the P&S August article. The performance curve showed the BEP flow at around 100 gpm....
Theory, Applications and Sizing of Air Valves

 Pumps & Systems, March 2008Soils with high concentrations of clay and silt can wreak havoc on construction sites, drain pipes, sewers and pumps. Users working with soils might want to...
Internal Joint Restraint for Municipal Applications
Corrosive, aggressive soil had eaten through a 35 year old ductile iron pipeline in the Port of Tampa area, causing a multitude of leaks that could not be repaired. Replacing the rotten pipe with more...
Pumps & Systems, June 2007 Last month, we discussed applications of low head axial flow pumps ("Field Testing: Theory vs. Reality," Pumping Prescriptions, May 2007). Knowing your system...
Pumps & Systems, March 2007Many pipeline systems throughout the U.S. are in need of maintenance, but this maintenance is often pushed back because there is no way to properly shut down the system....
Hydraulic Institute Pump FAQs January 2010
Q. I understand the significance for properly configured suction piping, but what are the piping requirements on the discharge side of a rotodynamic (centrifugal) pump?A. The maximum velocity at any...
Expanding Business with Video Pipeline Inspection
Two decades ago, EST Associates, Inc. started operations in Needham, Mass., to provide the New England area with environmental sampling and related monitoring services.Driven by the demands of a...
The Basics of Pipe Thermal Expansion
Materials expand when heated and contract when cooled. Pipes are not immune to these laws of nature, so they will also expand and contract with varying temperature.This article will introduce the...
