Global Pumps Market
As the cornerstone of all industrial applications, pumps continue to sustain their importance in a mature market characterized by steady growth and slow technology change. Key competitive factors within the global pumps market include price, delivery period, brand reputation, and service. Despite spanning several vertical applications, opportunity strikes this century old industry.

The Essence of System Vibrations
The dynamically loaded structural vibration system assumes its own unique natural frequency based on stiffness and mass. The design engineer's duty and responsibility is to analyze the proposed system to determine the resulting natural frequencies and the quality of the system. The engineer (designer) can then modify the design to achieve the required performance prior to construction, before the fact (on paper), not after the fact when the maintenance issues can become overwhelming.

Overhauling or servicing big pumps and valves means dealing with big bores. After installation in the field, valves and pumps often require maintenance to rid the inside diameter (ID) of foreign material, ranging from rust and corrosion to accumulated chemicals and biological matter. Improper cleaning and resurfacing of the IDs of those bores can mean fewer operating hours between servicing as well as degraded performance.

If pump cavitation is not detected and quickly eliminated, significant damage can occur to the impeller and other internal components. Since cavitation (the formation and collapse of vapor bubbles in the pumped fluid as it passes through the pump impeller) is often temporary or even induced by the process, timely knowledge of the condition is extremely important so operators can act to alleviate the problem and prevent damage.

Named for a technique commonly used on failing pumps, "percussion maintenance" - where a technician beats on the pump's stalled motor with a hammer or rubber mallet - often indicates motor deficiencies in his diaphragm pump. Though it is impossible for the maintenance department to predict when a pump will stall, such maintenance techniques are often the result of poor motor design.

Changes in the world economy, the markets we serve and the pump industry are continuing at an exponential rate. To a large extent, the pump industry has reacted to change more than it has been a driver of change. At the same time, the pump industry’s ability to manage through change has been reduced by industry consolidation and the loss of skilled talent to downsizing, retirement and other industries.Pumps & Systems, May 2007
Everybody knows that a rotating part or pump is going to produce vibration. Service personnel in the pump repair business, the air compressor industry, and electrical power generator providers all install products that helps eliminate those vibrations. Nobody wants to see a long run of pipe vibrate and pull the pipe hangers out of the ceiling. Falling pipe produces frowns from building owners.

Cavitation is a destructive condition that can destroy the inside of a pump before you even realize it is occurring. Early detection can minimize damage, reduce downtime, and save money. Cavitation involves the creation of bubbles formed when the fluid being pumped vaporizes due to a decrease in pressure as the fluid enters the pump. These bubbles are then acted on by the pump impeller, causing them to implode.
