Once a machine or system is up and running, monitoring the asset's operation and performance and deploying proper solutions when problems develop can pay big dividends.

Turbine failure can result in unwanted downtime and costly repairs. Early detection is key to keeping the plant running at optimum efficiency.

Cooling water pumps for power plant condenser cooling systems are large flow-rate, low- to medium-head units that operate at low rotational speeds.

Among artificial lift methods, pumps are the leading choice for many operators.

Electronic motor protection relays are available for general-purpose applications. They protect against problems such as overcurrent, phase loss and voltage unbalance.

Pumping systems that have many components also have many potential failure points. Proactive users monitor as much of the system as possible to address problems at the earliest sign.

In the east African country of Ethiopia, high-tech sugar production plants have been the focus of food-processing investments.

In the past few years, heating, ventilating and air conditioning (HVAC) services have shown considerable growth in the field of remote diagnostics and fault detection.

In the past decade, microprocessor controller technology has advanced to provide optimum functionality, improved microprocessor capacity and more sophisticated software algorithms—all at a reduced

To manage data from remote systems such as pump stations, overflow tanks or wells, most water treatment systems rely on a supervisory control and data acquisition (SCADA) system.

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.

Part 1 of this series (Pumps & Systems, March 2015) discussed what happens to a boiler feedwater (BFW) pump during plant transients.

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

In today’s high-volume pumping applications, energy efficiency and cost control are more important than ever.

Last month's column (Pumps & Systems, February 2014) reviewed the pump selection process and described how many users oversize pumps by adding design margins to account for unknown conditions present during the pump specification process.
