Flexible Pump Outlet Adapter for Existing Discharge Line Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oily and storm water pumping systems face challenges when replacing submersible pumps with different diameters, as this often requires replacing the entire discharge piping system, leading to significant downtime and costs.
Innovation Solution
A flexible adapter with a varying inner diameter is used to connect the existing pumping system to a new submersible pump with a different diameter, allowing for seamless replacement without modifying the existing discharge piping.
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 the existing discharge piping must be replaced
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 new pump outlet to a second diameter matching the existing piping, enabling compatibility without replacing the entire piping system.
Solution Approach 2:
The adapter assembly changes the dimensional parameter of the pump outlet by providing a reducing passage with varying diameter. This allows the system to accommodate pumps with different diameters while maintaining connection to the existing piping infrastructure.
2Adaptability or versatility
If the entire discharge piping system is replaced, then compatibility with the new pump is achieved, but system downtime and costs increase
Solution Approach 1:
The solution segments the connection system into three separate components: the new submersible pump, an intermediate adapter assembly, and the existing discharge piping. This segmentation allows only the necessary adapter to be installed rather than replacing the entire piping system, significantly reducing installation time and system downtime.
Solution Approach 2:
The adapter assembly is pre-configured with the appropriate reducing passage dimensions before installation. This preliminary preparation allows for quick installation that bridges the diameter mismatch between the new pump and existing piping without requiring on-site customization or extensive modifications.
3Adaptability or versatility
If the entire discharge piping system is replaced, then compatibility with the new pump is achieved, but costs increase
Solution Approach 1:
The adapter assembly serves as a cost-effective intermediary solution that preserves the existing discharge piping infrastructure. By using a relatively small adapter component instead of replacing the entire piping system, material costs are significantly reduced while still achieving full compatibility between the new pump and existing system.
Solution Approach 2:
The adapter assembly represents a relatively inexpensive, simple component compared to the costly discharge piping system. It provides an economical solution that achieves the necessary compatibility function without requiring expensive material replacements.

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.
