Centrifugal Pump, including dynamic pumps. These pumps are placed in the category of non-positive displacement pumps, which are transmitted to the fluid by rotating a propeller in that energy.
Like many other pumps, centrifugal pumps transfer energy from the rotating engine to the fluid. Some of this energy appears as a kinetic energy in the form of a speed, and it also amounts to a potential energy in the form of a pressure head that can carry the fluid against the gravity of the earth upward.
The transfer of energy from a rotating butterfly to a fluid to generate pressure and fluid motion is always described as the centrifugal force in the fluid.
Centrifugal pumps are the most widely used type of pump in the industry. On average, 75 percent of the pumps used in the industry are centrifuges.
These pumps work on the basis of centrifugal force theory. When the blade of the pump runs inside the chamber, it pushes the fluid out of the center. The fluid that is pushed out is drained through the outlet. This fluid will have a pressure that can be calculated by the step of the pump impeller as well as its rotational speed. As mentioned, these pumps have two main members, the body and the propeller.
Advantages of centrifugal pumps
- The price is reasonable
- Simple design
- Diversity in the butterflies
- Lower current costs than other pumps
- Occupy low space
Disadvantages of centrifugal pumps
- Need sealing
- Normally it does not provide high pressures and discharges
- Class pumps are very expensive for producing high pressures
