Industrial Pumps Basic Applications

Course details

COURSE OBJECTIVES

The course is designed for engineers, supervisors and technicians involved in centrifugal pumps maintenance and operation. Participants will understand pump technology and performance. Participants will be able to determine different types of seals and bearings and their problems. It provides in-depth understanding of pump maintenance and overhauling procedures. Participants will practice hands-on inspection and measurements of pump parts. All participants will disassemble and assemble the pump for complete overhaul and report the pump condition before and after overhauling, with emphasis on practical hands-on parts inspection using the modern maintenance techniques and troubleshooting real-life examples.

Who Should Attend?

• Maintenance, Technical support Engineers and Supervisors.
