ABU DHABI (13 November 2014)—At the record-setting Abu Dhabi International Petroleum Exhibition & Conference (ADIPEC), more than 60,000 visitors toured the halls of the Abu Dhabi National Exhibition Centre to see the latest innovations of more than 2,000 exhibitors.

Today marks the final day of the 2015 International Water Summit (IWS), a gathering of water and sustainability experts from around the globe. Thousands gathered in Abu Dhabi this week to discover solutions to problems such as water scarcity and efficiency.

This year during our annual Pumps & Systems On Tour video series, I had the pleasure to speak with leading managers at plants across the U.S. These experts shared their insights both into their companies’ initiatives as well as on the future of the pump market at large.

Starting January 17, the world’s leading experts will gather in Abu Dhabi for the Middle East’s largest meeting on sustainability—the Abu Dhabi Sustainability Week (ADSW).

The new year has brought new challenges for the oil industry. While consumers may enjoy lower prices at the pump, experts still worry about the long-term impact of cheap oil on the global workforce.

Abundant oil supplies from U.S. shale producers may have upset global markets in recent months, but one resource may present even more of a challenge to the international community in 2015—clean water. Demand has clearly outstripped supply in some of the world’s most arid regions.

Since its Nov. 27 meeting, the Organization of Petroleum Exporting Countries (OPEC) has witnessed even more turbulence in the oil market. Prices have dipped as low as little more than $60 per barrel.

Decreasing oil prices have put many companies and countries on edge this month, especially among the members of the Organization of Petroleum Exporting Countries (OPEC).

Last year, “Reduce Thrust and Extend Bearing Life” (Pumps & Systems, December 2013) discussed the benefits and some potential pitfalls of adjusting the axial clearance of American National Standards Ins

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.

For nearly 22 years, Pumps & Systems has been the leading technical magazine for pump users worldwide, delivering the most comprehensive pumping information across all the process industries.

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.

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

Who determines where pressure gauges are located in a pump system? How close to the pump should they be, and what happens if these rules are not followed?

I hope that my last column (Pumps & Systems, September 2014) provided a clearer definition of power factor and how it can be calculated.

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. In this column, two computer calculation tools will be detailed.

Power factor (PF) is an important component of an alternating current (AC) circuit, but understanding its actual effect can be difficult. Why is PF mysterious to many of us? It has to do with the way it is explained.

In my July 2014 column, I demonstrated that three-phase voltage variation can significantly affect several alternating current (AC) motor characteristics. If that variation is large, it can also reduce motor life.

When the pump selection process starts, the required flow of the is often the only known variable for an application. For example, a system must move 2,000 gallons per minute (gpm) from a holding tank to another tank or process.

In my June column on pump and motor testing, I said that three-phase voltage variation and unbalance can have a significant effect on motor insulation life. Voltage variation is defined as the difference between the motor nameplate voltage and the incoming source voltage.
