When you use the Stainless Steel Submersible Pump for the first time, it works flawlessly. It absorbs water and the water discharged is beautiful. But recently, you have noticed that preparations take longer. Moreover, once the pump is filled with water, it seems to be discharged with less force, and it takes longer to discharge the water. On the job site, this means more time, and time means more money. Therefore, you want to know why the pump speed is slow.
The short answer may be your impeller. However, in order to minimize future wear and tear and ensure that the correct pump type is used, you should understand how centrifugal pumps work and why the impeller is usually the main culprit in reducing pumping power.
We have all experienced centrifugal force. When we are sitting on a circular roller coaster, or when the driver turns at a higher speed, we are "pushed" into the door, which is what makes us sit in the seat. As you might expect, the centrifugal pump uses the same force to push water through the pump casing.
The impeller is the key equipment for generating centrifugal force. The impeller is installed on the motor shaft in the pump housing and rotates at a high speed. Although the detailed design of various impellers is different, they all follow the same principle.
The impeller uses (usually) blades on its surface to "push" the water off the center point of the shaft. Since the impeller is usually located in the center of the housing, the fluid is forced to flow to the outer edge, which is where the discharge port is located. The force or flow rate of a centrifugal pump depends on the design and size of the impeller and the speed of the rotating shaft.
