Different Centrifugal Pumps and Their Functionality

Most commonly, the pumps are visible in industrial set-ups and are most used there to ensure the smooth transfer and operation of the fluids like water. In most cases, the centrifugal pumps are employed for these situations and for several other applications that demand reliable and cost-effective solutions. The best feature of this machine is that it is extremely simple and easy to use. Another very important feature is that it uses the centrifugal forces to move fluids through the pipes.

The operation of this machine is extremely simple as it contributes the primer mover’s energy into kinetic energy. Once this is done, it takes that kinetic energy and converts into the pressure energy to pressurize the fluid to move in the pipes. There is a part called "Impeller" that has a central eye to allow the fluid to come into the motor. The impeller moves at a really high speed and forces the fluid to accelerate rapidly outwards from the casing. The benefit of this step is that this increases the pressure of the fluid and as a result, it gets pushed out of the pump with a gushing speed. This versatility and robustness of these machines ensure that they are asked for any minor or major task related to water transfer. But upon working on a regular basis, it needs regular maintenance and its absence can bring down the quality of the machine and its performance. The same can cause corrosion and quick-overheating of the machine.

The good thing about this version of water transfer pump is that it is available in a huge variety and this is the reason behind the popularity of this machine. Apart from this, they are available in a wide assortment, types, specifications, capabilities and materials used in their construction. One of them would be the primer type and this version is used expansively in the manufacturing industry. There are several other versions such as waste water pumps, jet pumps, close couple, end-suction and self-priming pumps.  

The closed couple version of this machine functions very much like the centrifugal version. It too utilizes an impeller driven by a motor shaft adapter that is directly connected to the electric driven motor. The head of this version is supported by a rear housing that is bolted directly to the motor flange. This version is seen used frequently in chemical processes, deionization of the water and also for the treatment of the waste water. For the last purpose, this version works in combination with the waste water pumps.

Similarly, there are self priming centrifugal pumps that are designed with a large volute. The main task of this volute is to enable the motor to re-prime itself in the lift conditions. The other version known as the end-suction version is made to allow the liquid to flow directly into the impeller and the design of this version forms a 90 degree angle between the inlet and the outlet.
