Advanced Bearing Materials for Processed Lubricated Systems
Pump manufacturers in a variety of industries are increasingly asked to deliver more with less; they need to handle increased loads with improved system efficiency but reduce envelope, environmental...
Today's electricians are often found working in applications outside the realm of what is traditionally considered "electrical." Through new programs sponsored by the IBEW-JATC training schools and...
Bearing Failure and Analysis
Rolling bearings are precision machine elements found in a wide variety of applications. They are typically reliable even under the toughest conditions. Under normal operating conditions, bearings...
Benefits from Proper Lubricant Monitoring and Analysis
Lubricants for rotating machinery primarily serve to separate rolling and sliding contact surfaces, protect highly finished bearing surfaces from corrosion, protect against contaminants (in the case...
Cavitation Issues During Multiple Pump Operation
Cavitation in pumps is a well known but unwelcome phenomenon. When imploding bubbles of pumped product undergo rapid phase transformation from liquid to vapor state, and then back to liquid, the...
Computing Flow through Wastewater Lift Stations
Lift stations can be difficult and costly to monitor, especially when the stations are located in remote areas.Despite the challenge, collection system operators need to monitor lift stations to track...
Coupling Considerations for Pump Applications
A flexible coupling's primary functions are connecting two shafts, transmitting power from a driver shaft to a driven shaft and accommodating the misalignment between them. With only these...
Disc Couplings 101
Most of us probably never notice the spinning cylinder mounted between the pump and motor, except how easy it is to dis/assemble when a pump or motor is changed out. Otherwise, the disc coupling never...
Explosion Proof Couplings
Mechanically generated sparks, electrostatic discharge and high surface temperatures are all potential ignition sources in explosive atmospheres. Flexible couplings play a significant role in creating...
FSA Sealing Sense
This article is related to an earlier Sealing Sense that answered the question "When and how do I use API Flush Plan 53?" (June 2005). Now we will focus on the three variances of Plan 53 (see Figure...
Loudon Water Implements Vibration Monitoring
As a public water provider, Loudon Water, a water and wastewater authority in Loudon, Va., must be able to supply water to meet the community's needs. As a non-profit organization, it needs to prevent...
Pump Noise and Vibration Attentuation
Unanticipated noise and vibration can be problematic for both occupants and processes within structures. Noise and vibration in piping systems can originate at pumps and other mechanical equipment. If...
Selecting the Best Industrial Vibration Instrumentation
What Are Your Vibration Monitoring Goals? Identifying goals before starting is key to designing a process tailored to specific needs. What are you hoping to accomplish by monitoring vibration?...
Soft Foot: The First Step to Precision Alignment
Soft foot is one of the most prevalent conditions found in rotating machinery. This condition, if not corrected, makes an alignment job much more difficult and sometimes impossible. If the internal...
Best Efficiency Point and Best Operation Point
Best Efficiency Point (BEP) is the point at which a pump is least prone to failure and its life expectancy is greatest
Q. If industry guidelines for intake design are followed, when is it advisable to conduct physical model tests of intake structures?A. Industry guidelines cannot always be followed. A properly...
Last month, we looked at tight versus loose pump performance. This month, we will consider additional factors that influence pump performance. The Effects of Pump Component Wear To further...
