In a typical plant, pumps often are controlled by semiconductors such as microprocessors, power electronics and variable frequency drives (VFDs) to digitally link assets and provide better process control. By using “smart”

The Jordan, Knauff & Company (JKC) Valve Stock Index was up 14.4 percent during the last 12 months, staying under the broader S&P 500 Index, which was up 22.1 percent. The JKC Pump Stock Index was up 24.1 percent during the same time.1

As the months pass, the evidence is becoming increasingly clear—North America is in the midst of a golden age of oil and natural gas production. Record levels of recovery in U.S. unconventional plays and Canadian oil-sands formations are driving vast production increases. According to the International Energy Agency, the U.S.

Countries in the Middle East and North Africa (MENA) have always been prominent food importers rather than producers. The punishing climate and topography have challenged efforts to expand the region’s food-processing indus-

Centrifugal pumps often experience repeat failures. Maintenance and reliability professionals are charged with preventing them. This four-part series explains the reasons behind repeat pump failures and uses a real-world field example involving boiler feedwater (BFW) pumps.

A ski slope in the middle of a desert—it sounds a bit radical. However, modern technology has made skiing a possibility all over the world, no matter the geography, climate or time of year.

During the last 20 years, the demand for freshwater in the Middle East and North Africa has increased significantly—particularly because this is one of the world’s most arid regions. Larger seawater reverse osmosis (RO) desalination plants have been built to meet the demand.

As the international demand for oil and gas rises, producers are heavily focusing on extending recovery from producing wells and developing new assets. In the Middle East and North Africa, the national oil companies (NOCs), which administer most of the oil and gas reserves in the region, are making plans to triple their production to keep up with current demand.

Operators are the eyes, ears and manipulators of switches and valves in their plants. They often receive training from a two-year associate degree program or on-the-job training. Their training may or may not cover how their equipment works or the significance of pump performance curves.

Sewage pumps operate based on Daniel Bernoulli’s principles (Hydrodynamica, 1738), which define the effects of balanced energy on fluid systems. This equation employs kinetic pressure and potential energies that are required to move a matrix of solids and water through a conduit with specific properties.

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

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?

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

The global water crisis claims 5,500 lives each day—more than war, natural disasters, AIDS or hunger. It is a sobering problem but not an impossible one to solve.

ASTON, Pennsylvania (Sept. 18, 2014) – The Mid-Atlantic Pump & Process Equipment Symposium X was held Sept. 18, in Aston, Pennsylvania. Nearly 300 individuals representing 110 organizations that are customers of Geiger Pump and Equipment attended the single-day symposium.
