A centrifugal water pump is one that moves fluid outward from the center point of rotation. An impeller is the component that does the work, harnessing the power of the motor to ensure the fluids are pumped effectively and efficiently. The impeller generates pressure which is then converted into velocity as the outward movement of the fluid stays confined in what is known as a pump casing. In most cases, the pump casing is a short cylinder with an inlet, known as an eye.
This is the heart of the centrifugal pump. It lies in the middle of the pumping system and has curved blades known as vanes which rotate. The impeller is immersed in water and the motor which spins the impeller, is what produces the centrifugal force.
The impeller is also responsible for the following:
One of the most commonly used type of impeller is an open impeller. These are used in centrifugal water pumps and are very popular. They are used frequently because they:
Do Not Easily Clog
While many impellers can clog in certain situations, an open impeller rarely does.
When operating correctly, they can even move fluids with suspended solids in it. Suspended solids can include:
The main reason they are so frequently used is their ability to pump liquids containing suspended solids. Not all impellers are able to handle the work load.
By using the external adjustment, an open impeller can be easy to maintain. By adjusting the open impeller properly, it can extend its life by ensuring the proper clearance is maintained. Adjustments are more common when the open impeller’s parts begin to show signs of wear. The good news, is the adjustments are made outside the casing. There is no need to take the centrifugal pump apart to perform maintenance. This makes adjustments quick and less intrusive than on other impellers.
As with many components, proper maintenance is key to achieving a higher efficiency of the centrifugal pump.
