Some of the most important components of the auxiliary systems in power plant or process plant are the Centrifugal Pumps. A Centrifugal Pump is the heartbeat of a system. In order to keep fluids flowing through the system a Centrifugal Pump needs to be maintained in good condition and needs to be operated properly. Operators need to be able to understand the proper operating procedures and Maintenance personnel need to be able to understand the workings of the pump along with the maintenance procedures. Both Operations and Maintenance need to be able to understand pump and system curves to determine exactly how the pump can perform under all conditions. Operation and Maintenance personnel need to understand the troubleshooting techniques in order to determine the Seminar of action to take if a Centrifugal Pump is failing or has failed. It is also important for the operator to understand pump theory in order to understand how the fluid is moving through a Centrifugal Pump and what is needed to prevent the loss of the Centrifugal Pump.

HPC Technical Services “Centrifugal Pump” Seminar is intended to prepare you for pump selection, application, troubleshooting, and maintenance activities.

OBJECTIVES:  At the completion of this Seminar the participant will be able to:

  1. Describe how Centrifugal Pumps really work.
  2. Demonstrate the ability to read and interpret pump curves.
  3. Demonstrate the ability to read and interpret system curves.
  4. Describe how speed governs pump designs.
  5. Describe the terms NPSH, NPSHA, and NPSHR and why they are important.
  6. Describe how Centrifugal Pumps differ from in design and application.
  7. Demonstrate the knowledge necessary to determine what are your energy costs (relative to the pump selection).
  8. Describe proper name and functions of Centrifugal Pump components.
  9. List and describe the various causes of pump wear.
  10. Describe how pump performance is influenced by the bearings.
  11. Describe how to properly start a new pump.
  12. List and describe those factors that have an adverse impact upon performance.
  13. Describe systematic troubleshooting techniques that apply to pump operation & maintenance.
  14. Demonstrate the knowledge to properly inspect centrifugal pump components.
  15. Describe how to examine pump application versus design.
