Submersible Axial Flow Pump Installation Methods

The submersible axial flow pump is a specialized pump designed to operate underwater. It's an ideal choice for a range of applications including drainage, irrigation, water conservation projects, and urban water supply. Depending on the specific requirements and site conditions, there are several installation methods available for these pumps. Below is a comprehensive guide on the common installation techniques:

Well Installation:

In this method, the submersible pump is hoisted within a vertical well shaft. At the bottom of the shaft, there's a seating ring slightly smaller in diameter than the shaft itself. As the pump descends under its weight, its O-ring seals tightly against this seating ring. The pressure from the pump's operation further ensures this seal remains tight. This method is particularly suitable for locations with deep wells and minimal water level fluctuations. Its primary advantages are simplicity, ease of installation, and straightforward maintenance.

Floating Drum Installation:

Here, the submersible pump is connected to the outflow pipe via a floating drum. This setup allows the pump to float up and down with water level changes, maintaining an optimal submersion depth. This method is apt for locations with significant water level variations or where constructing a well shaft might be impractical or expensive. Its flexibility and cost-saving nature make it a popular choice.

Sled Installation:

The pump is affixed to a sled-like structure. During installation, it slides down a guide, with its suction segment submerged. This method leverages dams for installation and is movable. It's ideal for regions unsuitable for pump station construction, as it minimizes excavation efforts and thus saves on project costs.


Coupling Installation:

The submersible pump is automatically connected through a coupler with guide rail components. This design, inspired by the installation features of submersible sewage pumps, is efficient, cost-effective, and offers quick and easy maintenance. For servicing, one simply needs to lift the pump body along the guide rail.


Pipeline Installation:

In this setup, the submersible axial flow pump is installed within a pipeline. It boasts the characteristics of a submersible propeller pump but offers a higher lift at a competitive cost. It's particularly effective for short-distance secondary pressurization in pipelines.


In conclusion, the versatility in installation methods ensures that the submersible axial flow pump can be effectively utilized in a wide array of environments, catering to specific project needs and site conditions.
