We live in uncertain times when the price of oil can drop by 50 percent in a matter of months.

About 125,000 electrical submersible pumps (ESPs) operate globally in artificial lift applications, producing 60 percent of the world's oil.

Many pumping stations and other remote locations need a local operator interface and remote monitoring but cannot afford a personal computer (PC)-based human machine interface (HMI).

Water pumps have been helping people irrigate for more than 4,000 years, since the Egyptians invented a basic pumping device called a shaduf.

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.

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.

I received many comments from Pumps & Systems readers on "How to Calculate Pump Specific Speed" (Pumps & Systems, January 2015) and "How Efficien

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