Common Application of Centrifugal Pump in Industry

Centrifugal pumps are one of the most common industrial applications for water supply, transportation, and distribution. With the increasing digitization and Internet of Things (IoT), water resource management will still be the foundation of future cities. Centrifugal pumps are suitable for pumping low-viscosity liquids or media. Depending on the design, centrifugal pumps are made of robust equipment as they are designed for high-speed operation. Usually, they can operate with high efficiency.

Application of centrifugal pump in industry

Centrifugal pumps can pump large amounts of fluids and transport them with stable flow rates. Generally, centrifugal pumps have relatively high cost-effectiveness. The structural design of most common centrifugal pumps is usually relatively simple with only a few component parts. Their design can ensure that they operate with the same performance and don't require a lot of maintenance work.

The pump mechanism of centrifugal pumps uses rotating impellers to suck water into the pump's suction port. The centrifugal force generated by the rotation of the impeller increases the water pressure. Then, pressurized water is discharged through the pump housing and outlet valve.

The disadvantage of using centrifugal pumps is that they need to be primed before use (or the suction port must have a certain immersion depth). This means you need to provide input fluid before running the pump. Centrifugal pumps cannot run dry without medium.

Centrifugal pumps are very suitable for water supply to residential areas. Their operating efficiency is best when they are submerged underwater or located below the input fluid source level.

Centrifugal pumps are also very suitable for industrial fire-fighting and fire extinguishing systems. Centrifugal pumps are ideal for fire extinguishing systems as they naturally have the ability to handle a large amount of water and discharge it at extremely high flow rates. They can also adjust the flow rate over long distances, making them effective in the fire protection systems of the entire industrial joint venture and building.

The centrifugal pump transfers the speed generated by the rotating impeller in the direction of fluid flow. The rotating impeller is a hydraulic component that transfers the speed generated to the pumped fluid.

The basic working principle of a centrifugal pump is to convert the speed generated by the rotating impeller into fluid flow rate. In other words, rotating impellers use their speed to push fluid to where it should flow. The fluid is pushed to the outlet and discharged there.

Centrifugal pumps are suitable for industrial applications in flood control systems

However, the need for priming before starting the centrifugal pump is one of its obvious limitations. But when centrifugal pumps are installed in flood control and its control systems, this inherent limitation can be turned into an advantage.

Combined with the fact that they operate best when submerged (in water), the start-up requirement of centrifugal pumps makes them very suitable for flood control systems. In other words, centrifugal pumps are ideal for flood control applications because they run best when they are submerged in floodwaters. They won't even start unless they are flooded.

The basic working principle of a centrifugal pump is to pump out the floodwaters and transport them to lower water levels or low-lying areas where they can be discharged into natural storage pools (bodies of water). The centrifugal pump creates forced eddy current, and the rotation of the impeller produces a speed that causes a vortex near the inlet of the pump system to suck in water.

The artificial water body generated by floods is then forcibly sucked into the inlet pipeline. After suction, the pressurized floodwater is propelled by the rotating impeller, flows through the pump outlet, and flows out of the pipeline. The rotation of the impeller generates external torque near the inlet of the suction pipe. This external torque is a dynamic force that generates a forced eddy current and sucks the floodwater inward to the inlet of the centrifugal pump impeller.
