Dynamic pumps pumps that his office is not changed during the pump working. The pump has a main element of a rotor with a blade that rotates at high speed. Incoming fluid is accelerated by blades which raise the absolute speed and the fluid pressure and flow through volut throw. Classified as dynamic pumps, among others:
a. Axial pump
The working principle of this pump is as follows, rotation of the blades will suck the fluid to be pumped and pressed into the press in the axial direction or perpendicular. Axial pump is typically produced for the needs of the pump with low head and large flow capacity. In the application of this type of pump is widely used for irrigation.
Figure 50. Scheme of the Axial Pump
b. Bury black pumps
Embedded pump uses electric power to drive the motor. The motor has a shaft that is perpendicular to the blade. Because the position of the blades of one shaft to the motor, then when the motor is running, the blades will spin and the water that was in the tub, lifted by a suction blade contained in the blades. To hold water that has been sucked up by the blades, that does not leak back into the suction tub, the water retained by lower difusser located at the bottom of the pump.

c. Hydraulic Pump Ramp
Is a pump that does not use electrical energy / fuel to work. Working with system dynamic pressure or force the use of water arising from the flow of water from the water source to the pump, the force used to move the valve working with high frequency, in order to obtain a large force to push water upwards.
