Introduction
The purpose of this course will be to develop a working knowledge of the different types of positive displacement pumps, as well as the different procedures associated with the operation and installation of positive displacement pumps. With the completion of this course, the participants will be equipped with the basic knowledge required to install and repair these pumps.
Technicians are required to have a technical comprehension of pumps, an understanding of the different types and applications or types of pumps to use. The technicians that participate in this course will be better equipped to repair, maintain, install, and commission pumps and their related systems, while increasing the knowledge within their maintenance team. This, in turn, will promote the safe and efficient productivity of the systems. With further on-job training and experience, the technicians will be able to attend more advanced training and therefore enhancing the maintenance team’s capabilities and knowledge.
Objectives
- To describe the behavior and the operation of pumps
- To analyze the technical solutions applied in their units
- To establish a diagnosis of incidents and participate in troubleshooting meetings
- To identify essential elements in pump selection
- To provide a better understanding of centrifugal and positive displacement pumps technology and operating principle
By the end of the course, participants will be able to:
Training Methodology
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations.
Who Should Attend?
This course is intended for all Engineers and technical staff involved in centrifugal and positive displacement pump operation, maintenance or engineering.
