Centrifugal and Positive Displacement Pump Fundamentals
In Centrifugal and Positive Displacement Pump Fundamentals, you'll learn ...
- Types of centrifugal pumps, including radial flow, axial flow, mixed flow and multi-stage
- Major components of centrifugal pumps, including the volute, impeller, wearing rings, lantern rings, stuffing boxes and mechanical seals
- Types of PD pumps, including reciprocating, gear, screw, lobe, sliding vane and diaphragm
- How cavitation can destroy a pump and how to prevent it
Pumps can be divided into two major categories - kinetic and positive displacement. Kinetic pumps can be further subdivided into centrifugal pumps (the vast majority of kinetic pumps) and special effects pumps.
The operating principle of centrifugal pumps and positive displacement pumps are quite different. Centrifugal pumps operate by imparting velocity energy to the fluid, which is converted to pressure energy upon exiting the pump casing. A positive displacement pump moves a fixed volume of fluid within the pump casing by applying a force to moveable boundaries containing the fluid volume.
Before attempting to select a pump for a particular application, it is important to understand the types of pumps available and how they operate. This course covers the fundamentals of centrifugal and positive displacement pumps, including the major components of a pump, the operating principle and the different types of pumps available within each category.
