Pump Bearing Cartridge Coupling Above Centerline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump designs present challenges during installation conversion due to varying center heights, bolt patterns, and drive configurations, often requiring costly and time-consuming removal of concrete foundations when replacing old pumps with new ones.
Innovation Solution
A pump design featuring a bearing cartridge coupled with a pedestal, where the bearing cartridge and pedestal couple together substantially at or above the centerline of the bearing cartridge, reducing center height requirements, and an adjustable mounting assembly with threaded bolts and nuts allows the bearing cartridge to slide, enabling easier installation without disturbing the foundation or piping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pump designs with adjusting screws located below the bearing cartridge are used, then the adjusting mechanism is accessible for maintenance, but the center height increases making installation conversion difficult and expensive
Solution Approach 1:
The patent inverts the traditional arrangement by locating the adjusting mechanism above the bearing cartridge instead of below it. The adjusting screw is positioned on the top surface of the bearing cartridge, allowing access from above while reducing the center height. This inversion resolves the contradiction by maintaining adjustability without requiring increased center height.
Solution Approach 2:
The patent changes the spatial arrangement by moving the adjusting mechanism from a vertical position below the bearing cartridge to a horizontal position on the top surface. This dimensional repositioning allows the adjusting screw to be accessible from the top rather than requiring vertical space below, thereby reducing center height while maintaining operational accessibility.
2Adaptability or versatility
If various pump designs with different center heights and bolt patterns are used, then design flexibility is improved, but installation conversion becomes complex and requires foundation removal
Solution Approach 1:
The patent creates a universal mounting interface on the bearing cartridge that can accommodate multiple bolt patterns and drive configurations. The top surface mounting arrangement provides standardized attachment points that can adapt to different pump designs and competitor equipment, enabling a single pump model to replace various others without foundation modifications.
Solution Approach 2:
The patent incorporates adjustable mounting features that allow the bearing cartridge position to be modified during installation. This dynamic adjustment capability enables adaptation to different foundation conditions and piping arrangements, simplifying installation conversion while maintaining design flexibility.
3Stability of the object's composition
If the bearing cartridge is coupled to the pedestal below the centerline, then structural stability is improved, but the center height increases limiting replacement options
Solution Approach 1:
The patent inverts the traditional coupling arrangement by positioning the bearing cartridge-pedestal coupling interface at or above the centerline instead of below it. This inversion reduces the center height while maintaining structural stability through alternative support configurations and mounting designs that compensate for the elevated coupling position.

AI summary
Apparatus is provided featuring a bearing cartridge in combination with a pedestal. The bearing cartridge may be configured to be coupled to a pumping assembly combination and having a predetermined centerline. The pedestal may be configured with an axial channel to receive and support the bearing cartridge and allow the bearing cartridge to slide therein. The bearing cartridge and the pedestal are configured to couple together substantially at or above the centerline of the bearing cartridge in order to reduce center height requirements of the apparatus, where the center height is defined as the distance between the centerline of the bearing cartridge and the bottom surface of the pedestal supporting the bearing cartridge. The apparatus takes the form of a pump or pumping assembly, arrangement or combination, including a slurry-type pump or a centrifugal pump.
