A roto dynamic pump consists of a rotating impeller which is used to raise the fluid. The word “rotodynamic pump” might make it sound a bit complicated but in reality, the mechanism of these pumps are very simple and easy to understand.
Even an individual who doesn’t have any know how about physics or pumps can grasp the operations of this pump. The principle used in these types of pumps is that they convert the electric energy to kinetic energy which is then used to compel and pressurize the fluid to raise its level. A multistage pump consists of two or more impellers. The prime purpose of a multistage pump is to generate a high head and to eject the fluids.
Various multistage pump supplier provide pumps that are tailored according to the needs and specifications of the clients. If you want to raise the level of liquids than you have to install the impellers on different shafts making a parallel pattern, whereas generation of a high head requires a series pattern in which the impellers are installed on similar shafts. There are other types of centrifugal pumps besides the multistage pump.
