For the last few centuries, pumping systems and the pump industry have been relatively uncomplicated. Beginning in the 1950s, however, pump manufacturers arose from machining shops, and a stream of acquisitions across the globe created a new and rigorous demand for pumps.

An increasing number of industrial plants are reducing the spare parts inventories stored at their facilities. At the same time, they are replacing fewer pumps because of capital constraints and have determined that remanufacturing existing equipment is the best path forward. Many of the pumps within these facilities have exceeded 50 years of service.

Choosing the right dewatering method can be essential to ensuring a profitable beginning to any construction project. Before starting a project, contractors should consider the three most common methods for dewatering a site: open pumping, slurry walls and predraining.

In this two-part series, how transient events in process equipment affect other system components will be discussed. Part 1 covers how deaerators (DAs) may be affected by generator trips and how these deaerator transients may also affect system pumps.

The Jordan, Knauff & Company (JKC) Valve Stock Index was down 13.5 percent over the last 12 months, while the broader S&P 500 Index was up 11.4 percent. The JKC Pump Stock Index decreased 12.9 percent for the same time period.1

A pulsation dampener is a vessel with pressurized gas inside, normally nitrogen. The initial filling or inflating gas pressure inside the dampener must always be lower than the pressure of the circuit where it is installed. The inflating gas pressure of the dampener is designated P0.

In 2014, this column focused on improving the operation of piping systems by performing pumped system assessments. The columns have covered energy cost balance sheets, the assessment process and the performance of sample assessments. By now, readers are aware that all the equipment found in a piping system falls into one of three categories:

A Southwest mining company, as part of its expansion plans, invited bids for a complete tailings reclaim water system. The proposal called for multiple system features, including pumps, motors, valves, piping, floating pump barges and skid-mounted booster stations.

Q. What specifications are required for series and parallel pump operations?

This column is about the most common mistakes pump end users make daily. It is also about how to avoid these mistakes and how to fix them.

I learned these lessons the hard way.

A reciprocating power pump, as depicted in Figure 1, is a displacement machine. It has characteristics that are different than a centrifugal pump.
