My Enquiry List: 0 items View list. Enquiry List. There are two main families of pumps; positive displacement and centrifugal rotodynamic , both of which have their uses and best areas of application. It is important however to be able to identify when each pump type should be selected, which ultimately comes down to their working principle and the application at hand. Positive displacement pumps are characterised by an operation that moves fluid by trapping a fixed volume, usually in a cavity, and then forces that trapped fluid into the discharge pipe.

Classification of Pumps

Reciprocating pumps are used where the delivery pressure of the fluid is quite large. In this article, we will discuss on Single-acting Reciprocating Pump. As the name itself indicates that it has a single component of the suction valve, delivery valve, suction pipe, and delivery pipe along with a single-piston. Reciprocating Pump is a Positive Displacement type pump that works on the principle of movement of the piston in forwarding and backward directions whereas the Centrifugal pump uses the kinetic energy of the impeller to supply the liquid from one place to another place. Reciprocating pumps are in use where a certain quantity of fluid mostly sump has to be transported from the lowest region to the highest region by the application of pressure.

Centrifugal Pumps Overview

Generally Pumps classification done on the basis of its mechanical configuration and their working principle. Classification of pumps mainly divided into two major categories:. Dynamic pumps impart velocity and pressure to the fluid as it moves past or through the pump impeller and, subsequently, convert some of that velocity into additional pressure. It is also called Kinetic pumps.

The pump casing is specially designed to constrict the fluid from the pump inlet, direct it into the impeller and then slow and control the fluid before discharge. The impeller is the key component of a centrifugal pump. It consists of a series of curved vanes.

Centrifugal Pumps are the most popular and commonly used type of pump for the transfer of fluids. In simple words, it is a pump that uses a rotating impeller to move water or other fluids by using centrifugal force. Centrifugal Pumps are useful since they can generally handle large quantities of fluids, provide very high flow rates which may vary with the changes in the Total Dynamic Head TDH of the particular piping system and have the ability to adjust their flow rates over a wide range. More viscous liquids such as 10 or 20 wt. For viscous liquids of more than 30 wt.

There are different types of pumps available in the market. This article will assist you to know the main functionalities of each type of pump. The type of pump, as well as selection, mainly depend on our requirement. The application mainly includes the type of fluid you desire to pump, the distance you desire to move the fluid, and the quantity you require to get over a particular time frame. However, it is complicated to recognize accurately what kind of pump you must select. The identifying of the pump can be done with the design as well as positions.

Pump is a machine or mechanical equipment which is required to lift liquid from low level to high level or to flow liquid from low pressure area to high pressure area or as a booster in a piping network system. Principally, pump converts mechanical energy of motor into fluid flow energy. Pump also can be used in process operations that requires a high hydraulic pressure.
