Introduction

Pumps are versatile and important fluid machine 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 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 operate successfully 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.
