Latest Piping Articles

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.

Users have several options for controlling piping systems. Previous columns established that every piping system is composed of pump elements, process elements and control elements.

I received a lot of feedback on my column “How Much Energy Do Pipes Remove?” in the September issue of Pumps & Systems

Last month’s column discussed the pre-screening process that identifies and prioritizes systems with a high probability of significant energy savings.

In sewage grinder pumps, domestic wastewater from one or a few households flows by gravitation to a pumping station equipped with one or two grinder pumps, having a discharge pipe of nominal diame

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 consumption

Part One of this series (Pumps & Systems, August 2014), discussed the new American National Standards Institute/Hydraulic Institute (ANSI/HI 9.8) design standard requirements.


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
