Centrifugal Pumps Principles & Operations

Introduction

The seminar will introduce delegates to the different types of pumps and their associated terminology. Centrifugal pumps, packing, mechanical seals and sealing systems, bearings and couplings will all be discussed.

The application of the different types of pumps will be discussed along with their suitability for different operational duties. Pump operation, troubleshooting and maintenance will be dealt with in depth.

Target Audience

This seminar is directed towards Supervisors, Team Leaders and Managers in Maintenance, Engineering and Production . The seminar will also benefit anyone who wishes to update themselves on pump technology, judge the suitability of different types of pumps for their needs, and learn how to operate and maintain them for the benefit of their organisations.

Objectives

At the end of this seminar participants will:

Have an understanding of centrifugal 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.

Key Benefits

The knowledge gained in this seminar will:

enable the delegate to optimise the operation and maintenance of centrifugal pumps.
give the delegate confidence to carry out failure analyses on pumps thereby avoiding repetitive failures.
allow tighter control of maintenance budgets by the avoidance of unplanned equipment failures in service.

Training Methodology

The seminar will be conducted along workshop principles with formal lectures, case studies and interactive worked examples. Relevant case studies will be provided to illustrate the application of each tool in an operations environment. Each learning point will be re-enforced with practical exercises. There will be ample opportunities for discussion and sharing experiences.

Organisational Impact

On completion of this seminar the delegate will be able to critically analyse the methodologies employed within the organisation and instigate improvements where required.

Personal Impact

Technical knowledge is key to effective control and peer respect within any maintenance organisation; when this is achieved personal satisfaction follows. This seminar will give the delegate the required level of technical knowledge and skill to achieve that personal satisfaction.

Competencies

· Understanding of pump operating and maintenance techniques.

· Ability to put in place measures to quantify equipment condition.

· Interface with pump equipment providers.

· Identify and specify new and replacement pumps.
