USE OF CENTRIFUGAL PUMP IMPELLER Part 2

2 MIXED FLOW IMPELLER

Type impleller can be said to be equal to the radial impeller differ only in the direction of flow only. The impeller is usually used for pumping liquids with a large capacity with a total head which is relatively low compared with the radial impeller but higher than the axial impeller. Impeller can be in the form of open and closed.

* Mixed flow impeller closed

Figure 1 looks from the front by removing the cover plate
Its use: ntuk clean water and a little dirty

* Mixed flow impeller is open

Figure 2 Uses: For clean water and a little dirty

3 AXIAL FLOW IMPELLER / PROPELLER

Axial flow impeller which is also called the propeller can be installed permanently or can be changed when the pump is opened or changed by the time the pump is operated. With impeller pump is used for pumping liquids with a large capacity but the total head is achieved relatively low. Examples of the use of axial impeller pump is to pump flood control, irrigation pumps, cooling water pumps power plants and others.

* Axial flow impeller remains

Figure 1 Usage: For water and wastewater

* Axial flow impeller which can be changed while the pump is opened
* Axial flow impeller which can be changed while the pump operates

4. SPECIAL IMPELLER

In addition to the impeller-impeller has been mentioned above there is also a type of impeller-type specific premises.

4.a Non-clogging impeller with free floe / vortex

Figure 1 Usage: For a liquid dirty, mud, liquids containing solids are quite large, long fibers, also for liquids containing gases.

4.b star impeller (impeller pump pulse)

Figure 2 Usage: for liquid really clean and liquids containing gases.

4.c Peripheral impeller (turbine impeller)
Figure 3 Usage: For a truly liquid cleaner and a liquid containing gas. Used for small capacity but have a total head high.
