1. Introduction to Submersible Axial Flow Pumps

Submersible axial flow pumps are innovative devices designed for efficient fluid movement in various applications. Unlike their conventional counterparts, these pumps operate underwater, allowing them to handle large volumes of liquid with minimal installation space. Understanding the technology behind these pumps is crucial for industries that rely on effective and efficient fluid management.

2. Working Principle of Submersible Axial Flow Pumps

Submersible axial flow pumps operate based on the principle of axial flow, where the fluid moves parallel to the pump shaft. The pump consists of an impeller, which is driven by an electric motor located above the water surface. As the impeller rotates, it creates a difference in pressure that draws fluid into the pump and expels it through the discharge outlet.
