Multistage Pump Overhauling

Introduction

This course instructs participants on the proper procedures for the preparation, rigging, disassembly, inspection and reassembly of multistage centrifugal pumps equivalent to those used in most industries. The pumps addressed include both horizontally split and radially split pumps. Participants will be introduced to maintenance and troubleshooting techniques that will enable them to diagnose, predict and prevent common problems associated with these pumps. They will be instructed in the proper installation of mechanical seal assemblies and the mechanical seal piping plans that apply to multi-stage pumps. Additional topics covered include design, installation and effective operation of multi-stage centrifugal pumps as well as the use of associated tools and measuring equipment.

Objectives

    Upon completion of the course, the participants will be able to:

    • Identify typical multi-stage pump designs and associated applications
    • Demonstrate in logical order the major tasks for the disassembly/assembly of a multi-stage centrifugal pump
    • Demonstrate routine maintenance and overhaul procedures
    • Inspect and determine when to replace and/or repair pump components
    • Describe various troubleshooting procedures

    At the end of this course participants will:

    • Have an understanding of the different types of pumps.
    • Be able to operate pumps as close as possible to the design efficiency.
    • Will be able to monitor pump efficiency, availability and reliability.
    • Have learnt about selection, operation and maintenance strategies.
    • Be able to troubleshoot pump problems.

Training Methodology

The training methodology is interactive with group exercises and is suitable for all employees involved in functions management. The pace and level of the training workshop is customized to the understanding of the delegates. Ongoing back-up and support is available after the training on request to the supplier, and the training course is also available for in-house presentation as well as for “Competency Transfer”.

Who Should Attend?

Service, maintenance, machine repair, or engineering staff of an industrial plant, institution or public utility which use multi-stage pumps and related equipment. Individuals should have direct involvement or responsibility for multi-stage pump installation, performance and maintenance.
