Pump Curves/Applications: Installation & Troubleshooting

Course length: 
One day
Theory & design
Course description

The most common machine to be driven by an electric motor is a pump. Centrifugal pumps are by far the most common devices for moving industrial liquids of all types. A thorough understanding of the design, implementation and maintenance of centrifugal pumps is essential for those working in the electric motor repair industry. This one-day seminar provides the practical knowledge service center personnel need to address customers’ pump-related motor issues, and the broader opportunities for pump maintenance, system optimization and energy savings.
