What is the primary purpose of a shaft sleeve?

• A. Enhance performance
• B. Protect the pump shaft
• C. Act as a power take-off
• D. Connect two bearings

Answer: (B)

The primary purpose of a shaft sleeve is to protect the pump shaft. This is accomplished by providing a wear-resistant surface that can withstand the abrasive effects of fluids within the pump and the mechanical wear that can occur at the points of contact with seals and bearings. A shaft sleeve can also facilitate maintenance by allowing for the replacement of the sleeve rather than the entire shaft if wear occurs. By using a sleeve, the integrity of the pump shaft is maintained, reducing the risk of damage to the pump's internal components and prolonging the overall life of the pump. This protective function is crucial in ensuring reliable operation and reducing downtime associated with repairs.
