The quality of the world’s sewage systems in past years has been influenced by four main factors: design of the system of pipes and valves, the design of the pump sump, the operation concept and t
Parts 1 and 2 of this series (Pumps & Systems, September and October 2015) discussed the engineering principles that dictate the operation of various elements of a piping system.
Part 1 of this series (Pumps & Systems, September 2015, online here) discussed the engineering principles that dict
Comprehensive information is crucial in process industries. When processing plants operate at optimal range, they increase overall productivity and reduce maintenance costs.
The concept of moving water from point A to point B has existed for thousands of years.
This series on troubleshooting piping systems draws on past columns in Pumps & Systems discussing the operation of individual components found in piping system.
This series discusses the control elements of a piping system, which improve the quality of the product.
For those of you old enough to remember Lawrence Welk, you’ll notice that the title of this brief column is the final quote from his show’s closing song. I am still a loyal fan of his reruns today.
In my last column (Pumps & Systems, October 2014), I explained that a capacitor’s current is totally out of phase with that of a motor’s magnetizing current.
A reciprocating power pump, as depicted in Figure 1, is a displacement machine. It has characteristics that are different than a centrifugal pump.
After reading two of my articles on power pump valves, valve springs and net positive suction head required (NPSHR), Brazilian engineer Ricardo Martuscelli emailed me to suggest that I creat
