Since municipal codes frequently deal with the most crucial areas of public life-covering the safety of life and property-it is understandable that preference is given to tools and methods that are "tried and true" over ones that are untested. The challenge becomes how to take advantage of new advances in technology while recognizing the importance of maintaining an uncompromising level of safety and security. The answer can lie in close cooperation between officials who champion the integrity of the municipal code system and individuals experienced in the implementation of innovative technologies.

To achieve a sustainable future, the green movement demands increased energy efficiency and conservation. Here is a look at how these changes will impact the water industry and its use of pumps and controls.

The Village of Mundelein, Ill., 35 miles northwest of Chicago, had a growing water demand and needed options for managing the increasing demand.

An automated monitor provides a live, continuous picture of exactly what is happening inside a turbine for protection, prediction, performance monitoring, and integration of the data with process control.

Wireless technology has significantly impacted business worldwide. It enables a greater degree of connectivity among devices for enhanced monitoring and utilization of existing assets. It has also led to the development of new applications that improve productivity, uptime and overall business performance.

The small town of Groin, Mo., has an excellent source of water. The water board says its wells and distribution system are coasting along at about half the maximum capacity. Since demand is growing at less than 2 percent per year, it would be reasonable to assume the current system is more than adequate for many years.

Comparing the vibration performance of identical or like machines can be used to detect defects and judge their severity.

In the foothills of the Andes, among the sprawling vineyards of picturesque Mendoza, Argentina, stands an innocuous equipment cabinet located by the side of an infrequently used mountain pass. The cabinet's superficial surface rust belies its importance as one of the most significant technological developments in modern day corrosion prevention. The cubicle, battered from years of an abrasive cocktail of arid Patagonian winds and coarse earth, hides the cradle of a revolutionary approach to cathodic protection. The equipment within the cabinet resulted in an entirely new range of products.

There are several ways to control two identical, parallel pumps operating under variable frequency control in pumping applications.

With the growth of wind farms, users are turning to condition monitoring and automatic lubrication systems for increased reliability.

Explore differential pressure, electromagnetic, vortex and swirl, and variable area (rotameters).

Beating occurs when two dynamic excitation sources (forces) are close together in frequency, and a pathway allows the two excitation forces to transfer to each other. The beating effect results because the frequencies are so close to each other that the waveforms alternately reinforce each other at some times and cancel each other at other times. When the vibration from each source adds constructively, the vibration increases. When the vibration adds destructively, the vibration decreases.

In the U.S. industrial sector, motor-driven systems consume 70 percent of all electricity. Motor-driven pumps account for more than 30 percent of that amount-more than any other application. Considering energy and maintenance represent more than 80 percent of total motor life cycle costs, a growing number of system designers, specifying engineers, maintenance professionals and end users are turning to variable speed motor control systems that can save up to 60 percent in energy costs as well as significantly reduce maintenance and equipment costs, improve process control and enhance system reliability.

Vibration monitoring of rotating equipment and analysis of the resulting data are effective ways to evaluate the health of production machinery in order to achieve best maintenance practices, extend equipment longevity, and avoid unplanned shutdowns. Plant equipment seldom fails without giving signals well in advance, so breakdowns can normally be predicted by listening for the warnings and passing that knowledge on to those in a position to prevent such problems.

Precision laser alignment can help end users avoid multiple problems in wind turbine applications.

Production, distribution and refining applications in the oil and gas industry rely heavily on motor-driven pumps and pumping systems. Keeping electric motors driving critical operations at peak performance is vital to ensure maximum profitability.

In the early days of adjustable frequency drive (AFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars and aluminum foil. Because AFDs improved performance and lowered maintenance costs, they replaced motor generator sets and DC drives. When the energy crises occurred in the early 1970s, saving energy became a critical goal, and the use of AFDs quickly spreadpump efficiency, into large pump applications and eventually into HVAC fan systems. pump efficiency, pump system optimization

On July 16 last year, a high-speed centrifugal pump failed catastrophically at a large refinery in South America, causing production losses and costing a substantial amount of money for repairs. The inboard bearing of the pump lost lubrication, overheated, and seized up.

Wireless technology is enabling INEOS Köln GmbH (Cologne, Germany) to detect blocked filters in polyethylene pellet transportation tubes that can lead to production downtime at its plant in Cologne.

Control panel products enhance smooth operations.
