Maintenance & Troubleshooting Tips for Couplings
Elastomeric couplings offer easy maintenance and lower bearing reaction forces.Flexible couplings are available in a variety of designs, types and sizes. The basic function of the flexible coupling is...
How can I select mechanical sealing systems using life cycle costs?
Mechanical sealing systems can be compared in a number of ways. Obviously, one of the more important areas is reliability. Another area that can be evaluated is life cycle cost or total cost of...
How Much Energy Can Be Saved by Redesigning (Not Replacing) Impeller Hydraulics?
We all know that a pump operating at off-design (to the left or right of the best efficiency point—BEP) flow wastes energy. But how much?Such questions face pump users all the time. Let's take a...
Healthy Control Valves
A simple maintenance routine can help ensure trouble-free valve operation.Whether the control valve in your system is the first one that has required maintenance or if you are experienced with...
AC Motors Part 5: AC Motor Life
One of the major impacts on motor life is common sense—or maybe the lack thereof!It always amazes me how many open drip proof (ODP) motors are used in agricultural irrigation applications where...
Centrifugal pumps need to be kept in tip-top condition to handle harsh liquid-terminal operations.Without question, liquid storage terminals play an integral role in the ongoing success and relevance...
Analyzing the Impeller Eye
This is a follow-up to my column on predicting centrifugal pump performance (Pump & Systems, May 2011), and offers equations that will enable the engineer to perform a partial analysis of the...
