Introduction to Overhung Pump
An overhung pump is a type of centrifugal pump where the impeller is mounted on the end of a shaft that is "overhung" from its bearings. This design allows for easy maintenance and access to the impeller and other internal components. Overhung pumps are widely used in various industries such as chemical, petroleum, power generation, and water treatment due to their simplicity, efficiency, and reliability. They can handle a wide range of fluids, from clean water to highly corrosive and abrasive substances.
