What is pumps and its types?
Pumps can be classified by their method of displacement into positive-displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valveless pumps. There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.
What are the two main classification of pumps?
Pumps are divided into 2 major categories: Dynamic and Positive Displacement (aka Displacement).
What are the types of Rotodynamic pumps?
The most common types of rotodynamic pumps are radial (centrifugal), mixed flow and axial flow (propeller) pumps, including pumps historically referred to as vertical turbine pumps.
What are the principles of pumps?
The operating principle of the pump is to convert mechanical energy to pressure. In operation, a rotating impeller accelerates a liquid and as the area of the pump casing expands the velocity of the fluid is converted to pressure. As a result pressurized fluid exits the pump discharge.
How are the different types of pumps classified?
Pumps come in a variety of sizes for a wide range of applications. They can be classified according to their basic operating principle as dynamic or displacement pumps. Dynamic pumps can be sub-classified as centrifugal and special effect pumps. Displacement pumps can be sub-classified as rotary or reciprocating pumps.
Which is an example of a gas pump?
Examples of such pumps would be those incorporated into automobiles or domestic appliances. Nev- ertheless, these pumps do fall within classifications and types covered in the handbook, and basic information on them may therefore be obtained herein after the type of pump has been identified.
What kind of flow does a centrifugal pump have?
This Portable Document Format (PDF) file contains bookmarks, thumbnails, and hyperlinks to help you navigate through the document. The modules listed in the Overview are linked to the corresponding pages. The three types of flow through a centrifugal pump are radial flow, axial flow, and mixed flow. Radial Flow Pumps.
What is the objective of a pumping system?
In a pumping system, the objective, in most cases, is either to transfer a liquid from a source to required destination, e.g. filling a high level reservoir, or to circulate liquid around a system, e.g. as a means of heat transfer in heat exchanger.
