The population of industrial pumps is aging. An article from Pumps & Systems’ August 2012 issue chronicled the repair of an 82-year old pump still in service in a major refinery. Like this refinery, many industrial operations use pumps that have been in service 30 to 50 years or more.
Legislation and regulations have been implemented in the chemical industry as a direct result of accidents that could have been prevented if companies had followed necessary safety precautions. This includes the classification, labeling and packaging of chemicals that could potentially pose a threat.
If someone is being chased by a lion in the Serengeti, he definitely wants to run fast. A world-class sprinter’s ability to run fast is a positive attribute that may help her win a gold medal. However, a peristaltic pump running fast may be detrimental to an end user’s operation.

What are line check valves? How do I install them to avoid the upthrust and downthrust that happens with submersible pumps?
Industrial equipment is an expensive preliminary expenditure that is followed by an inherent operational and maintenance support cost. Pumps can fail for many reasons, and when repairs are needed, end users should consider all aspects to determine cost versus value.
Known as the “Land of 10,000 Lakes,” Minnesota takes its environment and its water resources seriously.
A harmonic sound coming from within a pump station is not the sound municipal sewer system operators want to hear. From the rhythmic clunking inside the 4,000-gallon-per-minute Lift Station No. 9, Wayne Johnson knew he had an impending problem—perhaps a big one.
A large portion of the pipes, pumps, valves and other water infrastructure operating in the U.S. today dates back to the 1940s or earlier. With water systems crumbling, the U.S.

Brazilian engineer Ricardo Martuscelli emailed me to suggest that I create graphs that illustrate the effects of speed (rpm) and the density of the pumpage on the NPSH requirements of these machines.
