Question:

What is the recommended clearance between the pump shaft and impeller hub?

Answer:

The specific pump design and application can influence the recommended clearance between the pump shaft and impeller hub. However, a typical clearance range is generally between 0.010 to 0.030 inches (0.25 to 0.76 millimeters). This range of clearance enables proper fluid flow and prevents excessive friction, which could potentially cause wear and damage. It is worth noting that the clearance may require adjustment depending on various factors, including the type of fluid being pumped, operating temperature, and pump speed. To ensure optimal pump performance and longevity, it is crucial to consult the pump manufacturer's specifications and guidelines to maintain the appropriate clearance.
