Borehole Pump Foot Part Segmentation for Cost-Effective Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Borehole pumps, particularly the foot part, are difficult and costly to produce due to complex construction requiring lost core methods, making series production inefficient.
Innovation Solution
The foot part is constructed from two components produced using different manufacturing processes: a casting process for the motor-side component and metal powder injection molding for the pump-side component, allowing for a mechanically stable connection and filter function without lost cores, enabling cost-effective series production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the foot part is produced as a single complex cast component using lost core methods, then the mechanical strength and structural integrity are maintained, but the manufacturing complexity and production costs increase significantly
Solution Approach 1:
The foot part is divided into two separate components: a motor-side component produced by casting and a pump-side component produced by metal injection molding. This segmentation allows each component to be manufactured using the most suitable process for its specific requirements, reducing overall manufacturing complexity while maintaining structural integrity through precise joining of the segmented parts
2Stability of the object's composition
If the foot part is produced using traditional sheet metal construction, then the mechanical stability is achieved, but the production time and manufacturing costs increase
Solution Approach 1:
The invention changes the manufacturing parameters and processes from traditional sheet metal construction to a hybrid approach combining casting and metal injection molding. This parameter change enables more efficient series production while maintaining the mechanical stability required for the foot part's function
3Manufacturing precision
If the foot part is produced as a precision cast part, then the manufacturing precision is improved, but the production costs and difficulty increase due to lost core methods
Solution Approach 1:
By segmenting the foot part into two components manufactured by different processes, the invention achieves high manufacturing precision for both components while avoiding the difficulties of lost core methods. The metal injection molding process specifically enables complex geometries with high precision without requiring lost cores
Solution Approach 2:
The invention substitutes the mechanical lost core casting method with metal injection molding for the pump-side component. This substitution eliminates the need for lost cores while maintaining or improving manufacturing precision, thereby easing the manufacturing process

AI summary
The pump has a head part (3) and a foot part (2) made of stainless steel, and pump stages (1) integrated between the head part and the foot part. The foot part serves to connect the pump to a drive motor, where the pump includes inlet openings for delivering fluid. The foot part has a motor-side component (8) and a pump-side component (9) separated in radial planes and formed with different manufacturing processes. The motor-side component is manufactured with a casting process. The motor-side component has receivers for a fastening unit for connection to the motor and/or the head part.
