I received many comments and suggestions on proper installation practices, following my article “Grouting: Pumps and Telephone Poles,” Pumps & Systems, July 2010).
Last month, we studied the properties and effects of resistive, inductive and capacitive loads in an AC circuit.
Using pump system analysis, from simple to the complex
As a follow up on my AC Motors series, I thought it would be a good idea to provide a short overview of work, power and torque as it applies to the AC motor.
When selecting a pump for variable speed operation, a number of conditions must be evaluated.
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 impeller eye.
Starting can have a significant effect on the life of the winding insulation of an AC motor.
Energy efficiency and reduced consumption are important issues in the pump and motor marketplace.
