CLASSIFICATION OF PUMPS

Classification of pump bases on the fundamental of the applications which they will serve their own functions, properties of constructed material, the type of the liquids that they handle, and even their direction of installed formation. All kind of these classifications are limited by the subjects of their unique characteristics, So it will not overlap each others substantially.

The essential classification of basic system is defined by whichever energy added into the fluid of pumps. It causes the principle of identification can be shown and implemented such as delineates specific geometries.
FIGURE 1 Classification of dynamic pumps

Therefore, this classified system can be related directly to the pump itself so any external of consideration can be done such as material or construction consideration. Due to this system, pumps can be divided of two categories :
1. Dynamic flow rate
Energy is continuously added into the fluid to increase its own velocities so it will be useful for the machine, including of reduction velocity in discharge section.

2. Displacement

In which, energy forms, like application of force is periodically added into moveable fluid boundaries, so will result the increasing of fluid pressure as a value of fluid movement through out the discharge line such as ports of valves.

FIGURE 2 Classification of displacement pump

For further classifications, dynamic pump can be classified into various centrifugal pump and others. Meanwhile, the displacement pump can be divided into rotary and reciprocating pump. As a summary of pumps classification and sub division of dynamic pumps, presented by Figure 1, outline form significant classification. About various specific types of commercial displacement pumps are indicated in illustration of Figure 2.
