Flexible Pump Outlet Adapter for Mismatched Discharge Piping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oily and storm water pumping systems face downtime and high replacement costs when a submersible pump reaches the end of its service life, as new pumps may have different diameters, requiring extensive modifications or replacement of discharge piping.
Innovation Solution
A flexible adapter with a varying inner diameter allows for the replacement of submersible pumps with different diameters without modifying the existing system, maintaining discharge pressure and flow by connecting the new pump to the existing discharge line through a guide rail bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new submersible pump with a different diameter is installed, then pump replacement is achieved, but extensive modifications or replacement of discharge piping is required
Solution Approach 1:
An adapter assembly acts as an intermediary component between the new submersible pump and the existing discharge piping system. The adapter includes a reducing passage that transitions from a first diameter matching the existing discharge line to a second diameter matching the new pump outlet, enabling connection without modifying the existing piping infrastructure.
Solution Approach 2:
The adapter assembly is divided into separate modular components including the adapter body with reducing passage, guide rails, guide rail brackets, and coupling mechanisms. This segmentation allows for easy installation, removal, and replacement of the pump assembly as a complete unit without affecting the fixed discharge piping system.
2Adaptability or versatility
If extensive modifications or replacement of discharge piping is performed, then pump diameter compatibility is achieved, but system downtime and replacement costs increase
Solution Approach 1:
The adapter assembly is pre-configured with the appropriate reducing passage dimensions and connection mechanisms before installation. The guide rails and brackets are pre-positioned to guide the pump assembly into place, eliminating the need for on-site piping modifications and reducing installation time significantly.
Solution Approach 2:
The adapter serves as a pre-fabricated intermediary solution that bridges the diameter mismatch between different pump models and the existing discharge line, allowing rapid pump replacement without time-consuming piping work.
3Adaptability or versatility
If extensive modifications or replacement of discharge piping is performed, then pump diameter compatibility is achieved, but replacement costs increase
Solution Approach 1:
The adapter assembly provides a cost-effective intermediary solution that avoids the high expenses associated with replacing entire discharge piping systems. The adapter can be manufactured from standard materials like stainless steel or aluminum in various sizes to match different pump and piping combinations.
Solution Approach 2:
The adapter assembly represents a relatively low-cost, replaceable component compared to the expensive discharge piping system. If needed, the entire adapter assembly can be removed and replaced with a different configuration without affecting the permanent discharge piping infrastructure.

AI summary
An assembly, comprising a basin, a submersible pump, having an outlet, disposed within the basin, and an adapter. The adapter comprises a housing having a first side and a second side, a reducing passage extending axially through the housing from the first side to the second side, wherein the reducing passage has a varying inner diameter such that a first inner diameter transitions to a second inner diameter, a plurality of fastener receiving holes extending transversely through the housing and disposed radially and circumferentially around the reducing passage, and a plurality of fastening elements extending from the housing at the second side. The submersible pump outlet is connected to the adapter on the second side and an existing discharge line connected to the adapter on the first side. The adapter provides a transition from a diameter of the submersible pump outlet to a diameter of the existing discharge line.
