Basically, a repair is the simplest, least-involved way of "fixing" a pump, typically caused by a non-recurring accidental event, such as a broken shaft, failed seal, and so on. An overhaul is more involved. It may include changeover of all the bushings and shafts, reestablishing register fits, restoring impeller clearances, and similar work. An upgrade will include repair and overhaul work, but typically also includes hydraulic modifications to change pump performance - to increase or decrease flow, shift best efficiency point, change materials of construction, etc.

Even though control technology has become an integral part of many pumping systems, over half of our readers have not expressed much interest in pump controls. I think I know why - today's controls are simply not as intuitively understandable as they once were. Who wants to read about the advantages of PID control without a basic understanding of P, I, and D itself?
This two-part series takes a brief look at the hierarchy of process control technology and explains the function of those three (often confusing) letters. Remember, this column is entitled Pump Ed 101, not 301, so our purpose here is to present the basics and hopefully make some of those more advanced control articles a little more understandable.

Business Acumen or Deception of the Masses?
I felt a sense of anger when I first read the adage: "Perfect is the enemy of good." I guess this was because I was raised to always do my best and strive for perfection. We live in a culture that praises perfection and degrades imperfection.
So how can we reconcile these two philosophies? Is this adage solid business acumen or simply a means of convincing the masses to work more quickly? I have decided to explore this adage as it applies to industrial maintenance and offer some useful advice to our readers.

Do any of the following statements sound familiar?
-
We want more uptime from our plant.
-
Our maintenance events take too long.
-
When we come back on-line, it takes forever to get back in full production.
-
We seem to have more failures right after an outage.
If you recognize any of these statements, you would probably also agree with the statement that there is room for improvement with your maintenance events. What would it be like if you could turn your maintenance event into a racecar pit stop?

Over the years, the FSA Gasket Division has explored many specific sealing and gasketing issues in Sealing Sense. Regardless of all the insights provided, chances are that users of gaskets will be confronted at some point with a bolted flange connection that leaks. When this happens, those involved will (most ...

Q. Most centrifugal pumps have a horsepower characteristic curve which rises as rate of flow increases to some level and then levels off or turns downward. However, other pumps have more level power curves or even some that are higher at low rate of low. Why is this, and can it be a problem?

With its seemingly limitless supply of lower factory costs, more determined discipline in their factories and rapid acquisition of technological prowess, the Chinese pumps market appears to be unstoppable.
In emerging Asia markets, with growth rates of more than 20.0 percent a year in 2006, the Chinese market offers huge potential. Transport and other infrastructure in China is also in better shape than many other Asian countries and the quality and availability of suppliers is improving all the time, enabling highly integrated supply chains to develop within the country.

Critical Issues Facing Businesses That Cater to Municipal Needs
Municipal revenue and budgets have fluctuated over the past year due to changes in the housing market. Housing prices in most high growth states increased rapidly in the first half of this decade. Rising housing prices resulted in a rapidly increased real estate tax base and significant increase in municipal revenue and budgets. These same states are now experiencing sharp declines in housing prices, exacerbated by the well-publicized crisis in subprime mortgages.

Critical Issues
Public and private organizations that rely heavily upon pumps and rotating equipment for their operations face similar critical issues which demand solutions. One issue - the need for improved plant reliability and availability - is key to both public utilities providing water, wastewater, gas or electric services to local constituencies, and publicly traded corporations with processing and distribution operations around the world.

Critical Issues
We participate in both the municipal and industrial market segments. Each market group has its own distinct issues. From the municipal side, the real estate slowdown in the U.S. market is forcing foreclosures and/or property devaluation. As a result, local governments are faced with a double-edged sword-the tax base is reduced while the demand for services increases. The infrastructure of the sewer and water departments is being squeezed by lower budgets for routine maintenance and for upgrading of existing services.
