Using the example system in Figure 1, this series will focus on the process elements found in piping systems. In this example, a process fluid is pumped from a storage tank, PX-TK-120, through an end...
These forces can have destructive effects if not carefully considered in piping design.
These forces can have destructive effects if not carefully considered in piping design.
Designers can find short- and long-term savings by using a non-traditional approach.
Shifting trends in water use and a changing sewage composition cause complex problems for the world’s sewer systems.
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...

The imaging technique provides valuable data on concentration and material distribution for process industries.
System design and instrumentation decisions can impact the efficiency and maintenance requirements of these pumps in wastewater applications.
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...
Determining the right size and number of grinder pumps before installation ensures consistent performance.
In past “Pumping Prescriptions” columns this year, I have discussed the procedure of piping size selection when given the process flow requirement and how this affects the pump’s power...
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...
Design of the pump inlet piping can protect overall operation.
Different material and design combinations offer application-specific advantages.
Design of the pump inlet piping can protect overall operation.
Last month’s column described the process of creating an energy cost balance sheet for a piping system (see Figure 1). The manufacturer’s curve was used to calculate the cost of operation for the...
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...
Pumps & Systems, March 2007Q.What are the key requirements for good suction piping design for rotodynamic pumps?A.  Good suction piping design must eliminate air entrainment in the liquid,...
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...
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...
