Slurry Pump Shaft Spacers Description
The shaft spacer in a slurry pump is a component used to support the pump shaft. It is typically installed on the bearing housing. Its function is to secure the pump shaft, preventing misalignment or wobbling, thereby ensuring stable and efficient pump operation.The structure of a shaft spacer generally consists of the spacer body, spacer cover plate, gasket, bolts, etc., and it exhibits high wear resistance and corrosion resistance.
Pasnto offer all type shaft spacers for AH, HH, L, M series slurry pumps, SP/SPR vertical slurry pumps, G/GH gravel dredge pumps, AF froth slurry pumps etc.
Functions & Technical Advantages
The Shaft Spacer is typically installed between the pump shaft and the bearing in a slurry pump. Its main function is to provide an appropriate gap between the pump shaft and bearing, ensuring their proper operation and preventing excessive friction, wear, or heat generation.
Maintain Bearing Clearance
- Technical Advantages: During installation, the bearing spacer serves as a critical limiting component within the bearing assembly, precisely controlling the axial clearance between the pump shaft and the bearing.
- Performance Enhancement: Precise clearance is vital for normal bearing operation. It effectively prevents excessive or insufficient bearing preload, avoiding premature failure and abnormal heating. This ensures stable operation throughout the bearing’s design life while significantly reducing vibration and noise during pump operation.
Reduce Axial Force
- Technical Advantages: During slurry pump operation, the impeller and fluid medium generate significant axial thrust. As structural supports within the shaft sealing system, shaft sleeve shims help distribute and transfer portions of this axial force to fixed structures.
- Performance Enhancement: By ensuring sealing components (e.g., packing rings, shaft sleeves) maintain proper axial alignment, it mitigates compression or tension on the sealing system caused by impeller axial movement. This stabilizes the operating environment for seals (packing or mechanical seals), thereby improving sealing performance and reducing leakage caused by axial force fluctuations.
Transmit Torque
- Technical Advantages: Although the Shaft Spacer is not a primary power transmission component, it plays a critical role in connecting and positioning within the integrity of the entire shaft assembly. It ensures a tight, non-slip connection between the shaft sleeve, impeller, or bearing assembly.
- Performance Enhancement: In certain designs, spacers assist in stably transferring torque from the impeller to other shaft components through precise fitment, preventing component loosening or relative rotation. This is vital for maintaining pumping efficiency and structural integrity under high loads.
Prevent Leaks
- Technical Advantages: The Shaft Spacer serves as the foundational platform for the proper installation and operation of the entire sealing assembly, whether it be a packing seal or a mechanical seal.
- In packing seals, it precisely positions the stuffing box, ensuring uniform pressure and effective contact between the water seal ring and the packing.
- In mechanical seals, it ensures the rotating and stationary rings can mate at the correct axial distance, forming an effective sealing interface.
- Performance Enhancement:
Properly installed shaft spacers minimize axial movement, ensuring the sealing interface or packing remains in optimal working condition. This is crucial for achieving the slurry pump’s “zero leakage” or minimized leakage objectives.
Mateirals
| Types | Common brands | Main features and advantages |
| Stainless Steel | SS304, SS420 (Common), SS316 | Excellent corrosion resistance and moderate wear resistance, easy to weld and process, it is the first choice for standard configuration. |

How to Install the Shaft Spacer
- When replacing the shaft spacer,first remove all components from the pump shaft,then remove the old shaft spacer and clean it thoroughly.
- Inspect the diameter and depth of the mounting hole in the bearing housing to ensure they meet specifications.If any issues are found,repair them promptly.
- Place the new shaft spacer into the mounting hole,then install the spacer cover plate,gasket,bolts,etc.,one by one.Ensure no components are omitted.
- During installation,pay attention to the orientation and positioning of the shaft spacer to ensure it aligns correctly with the position and direction of the pump shaft.
Shaft Spacer Installation instructions
- Install in the Correct Direction: Ensure the shaft spacer is installed according to the design direction.
- Clean Components: Make sure all parts are clean before installation to avoid contamination.
- Check Fit: Verify that the shaft and bearing fit properly with the correct clearance.
- Lubricate: Apply appropriate lubrication to reduce friction.
- Avoid Over-tightening: Do not over-tighten to prevent deformation of the shaft spacer.
- Check Sealing: Ensure the shaft spacer has good sealing performance to prevent leaks.
How to Maintence the Shaft Spacer
- Periodically inspect the shaft spacer for wear and replace it promptly if wear is detected.
- Regularly clean the shaft spacer and bearing housing to maintain their proper working condition.
- Ensure the shaft spacer is installed in the correct position and orientation during assembly.
