Positive Displacement vs Centrifugal Pumps

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. Kinetic pumps are subdivided into two major groups and they are centrifugal pumps and positive displacement pumps.

mechanical principles of operation as. Positive Displacement Pumps. (a) Reciprocating Pump. (b) Rotary Pump. Variable Displacement Pumps. (a) Centrifugal.

General Overview of Types of Pumps on Ship

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.

Different Types of Pumps: Working and Their Applications

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. When you go to the water servicing of the bike, you can see that the water that is being used is collected from the sump only, and by the application of pressure via a nozzle, water is sprayed on to the vehicle.

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. Due to low pressure at suction side of pump, fluid will lift from certain depth, whereas due to high pressure at discharge side of pump, it will push fluid to lift until reach desired height.

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.

A pump is a device that moves fluids liquids or gases , or sometimes slurries , by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift , displacement , and gravity pumps. Pumps operate by some mechanism typically reciprocating or rotary , and consume energy to perform mechanical work moving the fluid.

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.

Without references, DESCRIBE the purpose, construction, and principles of operation for Centrifugal pumps are the most common type of pumps found in DOE facilities. Centrifugal pumps enjoy widespread application partly due to their ability to operate.
