Centrifugal Pumps: Selection, Operation & Maintenance

Course Overview:

Pumps are a major capital cost item, a key reliability problem, and consume vast amounts of energy. For most companies, the costs of owning and running pumps are much higher than they should be. A shortage of general knowledge on how to apply, specify, install, and operate pumping equipment is the major reason for these high costs. This training course is designed to address this problem. Our Total Pump Training course is an in-depth look at common pump applications, including selection, operation, troubleshooting, and maintenance. Individuals in the pump and piping system industries will find this to be a valuable course for learning the importance of proper pump operation and typical behavior in an application.

After completing this training, trainees should be able to describe the basic operation of a centrifugal pump, explain how centrifugal pumps can be classified, identify the main parts of a centrifugal pump, and describe problems that can occur in them and how to solve them. How to identify the requirement to select the proper pump in certain applications.

Course objective

Upon successful completion of this course, the student will be able to:

Understanding Centrifugal Pump Components and Function.
Knowing Operation of Centrifugal Pumps.
How to apply general procedures for Troubleshooting Centrifugal Pump Problems.
Understanding Sealing Systems used in Pumps including Mechanical Seal and Glands.

Who should attend?

This course is recommended for anyone involved with the selection, operation, maintenance, and troubleshooting of pumps:

Mechanical maintenance engineer.
Process/operation engineer.
Material engineer.
Pump Serviceman.
Mechanical maintenance technician.
Plant field operator.
