Flood Control Pump

 

Flood control pump is a drainage equipment designed to cope with flood disasters. Its main function is to use mechanical power to pump accumulated water from low-lying areas or flood prone points to high places or drainage systems during floods, in order to reduce the impact of floods on cities.
The submersible axial pumps, with features of the high flow rate and low head, are often used for drainage tasks in large areas of water. And it can directly dive into the water, which is suitable for emergency drainage in various complex environments. Its working principle is mainly based on the principles of centrifugal force and fluid mechanics. When the pump impeller rotates at high speed, the blades drive the water flow to rotate, generating centrifugal force, causing water to be thrown out of the pump casing, achieving drainage.

The submersible axial flow pump is widely used in industrial and agricultural water transportation, urban water supply, and water transfer projects. Submersible axial flow pump is suitable for low head and large flow occasions.

 

Flowrate: 1,000m3/hr--100,00m3/hr

Head:3m-15m

Speed:1450rpm,960rpm,730rpm

Material: Cast iron or stainless steel

 

 

Since the motor and the pump are integrated, the on-site installation does not require labor-intensive, time-consuming, and complicated axis alignment assembly procedures and the installation is very convenient and fast.

Due to submerged operation, the civil engineering and building structure engineering of the pumping station can be greatly simplified, the installation area can be reduced, and the total engineering cost of the pumping station can be saved by 30-40%.

 

There are multiple installation methods for submersible axial flow pumps, which can be applied to different flood control pump sites:

Column installation: After the submersible axial flow pump is connected inside the column, there are no anchor bolts, so the pump can be easily lifted out after installation. This installation method is normally used in flood control pump station.

Diagonal installation: Install the pump and outlet pipeline on the guide rail or slope, so that the pump unit can accurately reach the position. Diagonal installation has the advantages of minimal civil work and the simplest and fastest installation. It is often used in flood control and emergency rescue or temporary pump station construction

Gate type installation: By utilizing the mobility of the gate, not only can the bi-directional pumping and drainage function of pumping and drainage be achieved, but also the entire civil construction cost of auxiliary pumping station construction can be saved.
