The surface finish recommended for pump shafts relies on various factors including the pump type, operating conditions, and shaft material. Nevertheless, in general, it is advisable to have a smooth surface finish for pump shafts.
A smooth surface finish aids in the reduction of friction and wear between the pump shaft and other components like bearings or seals. It also decreases the likelihood of corrosion, enhances sealing, and improves the overall performance and efficiency of the pump.
The specific recommended surface finish value can differ but is typically expressed in terms of roughness average (Ra) or roughness height (Rz). For pump shafts, the typical Ra value ranges from 0.4 to 0.8 micrometers (16 to 32 microinches), while the Rz value ranges from 3 to 8 micrometers (120 to 320 microinches).
It is crucial to note that the surface finish must fall within the specified tolerance limits to ensure the proper fit and function of the pump shaft. Additionally, the surface finish should be achieved through appropriate machining processes such as grinding or polishing, and it must be free from any defects or irregularities that could compromise the pump's performance.
Ultimately, it is recommended to consult the pump manufacturer or refer to industry standards and guidelines to determine the specific surface finish requirements for pump shafts in a given application.

Ultimately, it is recommended to consult the pump manufacturer or refer to industry standards and guidelines to determine the specific surface finish requirements for pump shafts in a particular application.
The recommended surface finish for pump shafts is typically between 8 to 16 micro-inches Ra (roughness average) or 0.2 to 0.4 micrometers Ra. This range provides a balance between smoothness for reduced friction and wear, and enough texture to retain lubrication on the shaft surface.
