Product Description

The JINAOTE Large Flow Submersible Axial Flow Pump is designed for water transfer applications requiring large flow capacity with low pumping head. Unlike conventional dry-installed axial flow pump systems, this submersible design integrates the motor and pump into one compact unit, allowing direct operation underwater without complex shaft connection structures.

Typically used for applications with a head below 15 meters, submersible axial flow pumps are widely applied in flood control pumping stations, agricultural irrigation, municipal drainage, industrial water circulation, and water diversion projects.

By eliminating the need for long transmission shafts, separate motor rooms, and complicated installation alignment, the JINAOTE axial flow pump provides a more flexible solution for projects where space, construction cost, and operational stability are critical considerations.

Working Principle

The pump generates water thrust through the rotation of an axial-flow impeller. The impeller pushes water in a parallel direction along the pump shaft, creating a large-volume water flow with relatively low pressure.

Compared with traditional centrifugal pumps, axial flow pumps are more suitable for moving large quantities of water over short distances and low elevation differences.

The integrated submersible structure allows the pump to operate directly inside the water, improving motor cooling efficiency and reducing installation requirements.

Main Applications

In agriculture, it is used for irrigation and drainage; in municipal applications, for storm water and lightly contaminated wastewater; in industry, for process water, cooling water, and raw water supply; and in water conservancy, for water diversion projects. It is suitable for conveying clean water or lightly contaminated wastewater.

Features

1. Since the motor and pump are integrated into a single unit, there is no need for labor-intensive, time-consuming, and complex on-site shaft alignment procedures. Installation is extremely convenient and quick, eliminating the need to reserve a dedicated pump bay. Standby pumps can be stored in a warehouse, thereby saving on investment in the pump station’s intake basin. Because the pump operates submerged in water, civil engineering and structural work for the pump station can be greatly simplified, reducing the installation footprint and saving 30% to 40% of the total pump station construction cost.

2. Since the pump operates underwater with water flowing around the motor, noise levels are low and motor cooling is efficient. This allows for the construction of underground pump stations, preserving the surface landscape.

3. The use of submersible electric pumps is the most effective solution for constructing pump stations and addressing flood control issues in river and lake regions with significant water level fluctuations. It eliminates the need for a long shaft between the motor and pump, thereby enhancing operational safety and reliability.

FAQ

Q1: What is the difference between an axial flow pump and a centrifugal pump?

Axial flow pumps are designed for large flow rates and low heads, while centrifugal pumps are generally used for higher pressure and medium flow applications. Axial flow pumps are commonly used in flood control, irrigation, and water transfer projects.

Q2: Why choose a submersible axial flow pump instead of a traditional axial flow pump?

The submersible design integrates the motor and pump into one unit, eliminating shaft alignment problems and reducing installation requirements. It is especially suitable for projects with limited space or variable water levels.

Q3: Can this Large Flow Submersible Axial Flow Pump handle wastewater?

The pump is mainly designed for clean water and lightly contaminated wastewater applications. For wastewater containing large solid particles or heavy sludge, a customized pump design may be required.

Q4: What information is needed for pump selection?

Customers should provide:
Required flow rate (m³/h)
Pumping head (m)
Water conditions
