Pump monitoring instrumentation is often not included with installations, but proper sensors can protect a pump and help with efficient operation.

This article will define a business case for achieving significant rotating equipment maintenance and energy cost reduction at industrial and municipal facilities.

Lift stations can be difficult and costly to monitor, especially when the stations are located in remote areas.

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.

When it comes to pressure and flow, variable speed pumping applications can be divided into three basic categories. Constant pressure-variable flow (Cp-Vf) attempts to keep pressure relatively constant over a range of flows. Constant flow-variable pressure (Cf-Vp) tries to achieve the opposite by using varying pressure to keep flow constant. Variable pressure-variable flow (Vp-Vf) applications can accommodate a change in both.

Any time a measuring instrument is used in a plant, it is expected to provide reliable results.

The town of Walden rests on a high glacial plain in Colorado, just 20 miles from the Wyoming border in Jackson County. Situated in the center of a large open valley called North Park, the 734 residents (based on the 2000 census) of the town and the surrounding area refer to themselves as "North Parkers."

Outdated water systems are pumping beyond their original specifications, resulting in inefficient operation, higher maintenance and operation costs and the potential for a system shutdown. This article takes a look at updating the controls and pumps for a water system.

The DelMonte vegetable processing facility in Crystal City, Texas, is a cannery for spinach, carrots and beets. Located 40 miles from the Mexican border, the plant has been in operation since World War II. The facility's capacity for canned spinach currently approaches 800,000 cans per day, so it needs dependable equipment.

A crucial triumvirate for improving the bottom line. pump system optimization, pump efficiency

Explore hermetically sealed gauging probes for hostile environments like saw mills and wood processing plants.

Last year in “Trending Revelations in Vibration Analysis,” (Pumps & Systems, June 2009), I discussed the importance of statistic trending in vibrations analysis. Usually, as most would expect, vibrations gradually increase with time. This increase reflects the normal internal wear, accumulative misalignment and deformations that can occur within a pump. All these wear conditions will lead to eventual failure.

Released in January 2010, the SDT270 Ultrasonic Detector, in conjunction with its powerful database software, gives the earliest indication of bearing re-lubrication requirements, bearing failure, and pump cavitation.

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.

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.

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.
