Introduction

Pumps are versatile and important fluid machines that almost found in all engineering processes and applications. There are two main types of pumps: namely positive displacement and rotodynamic pumps. The first type may be classified as reciprocating and rotating pumps. Piston, plunger and diaphragm pumps represent the reciprocating pumps, while gear, screw lobe and sliding vane pumps represent the rotating pumps. The second type, namely the rotodynamic pumps may be centrifugal pumps, mixed-flow pumps and axial-flow pumps. Without pumps there would be no flow in pipes, tubes, conduits or equipment. Pumps create the pressure or head required to overcome friction loss due to flow and losses due to change in magnitude or direction of the flow as well as any shock losses. Also, pumps charge the fluid by the head to overcome gravity and increase the fluid potential energy. Mechanical seals play an important role in pumps to prevent leakage. A mechanical seal must contain four functional components primary sealing surfaces, secondary sealing surfaces, a means of actuation and a means of drive.

Objective

The basic and advanced pump technology is required to:

• Differentiate between different types of pumps

• Know and recognize the pump component and structure

• Help learning how to successfully operate the pump

• To diagnose the problems of operation as cavitation causes and overcoming these causes.

• Understand the causes of axial and radial thrust in pumps

• Successfully select, troubleshoot and maintain pumping equipment.

Audience

This course is designed for:

• Operators, and maintenance groups

• Engineers and supervisors as well as those in the design of piping systems

• Responsible engineers for purchasing and commissioning pumps

Methodology

A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions and motivate everybody to find the right answers. The delegates will also be encouraged to raise their own questions and to share in the development of the right answers using their own analysis and experiences. Tests of the multiple-choice type will be made available on a daily basis to examine the effectiveness of delivering the course.

Very useful Course Materials will be given.
