Submersible axial flow pump is a kind of pump with axial impeller. It is a new style that produced by many experts in APK. We absorbed foreign advanced technology, through effortless experiments and finally created such high capacity submersible pump. There are several kinds of axial flow submersible pump for sale now in our company.
APK not only pays special attention on quality of products, but also takes social responsibility into consideration. As water occupies vital role in human life, we constantly innovate our technology to make environmental friendly products. This kind of pump added special material to reduce noisy pollution and energy saving.

Applications
The head of submersible axial flow pump is 2-8 m. It is a low head, high capacity pump. Pump station in low lying and plain areas especially need such pumps. They are used for large area of drainage and irrigation.
Performance
- axial flow submersible pump uses water cooler submersible motor for immersing into water for a long time. This kind of motor adapted double or triple seal structure, so that no water can be leaked out of the motor.
- Leak detection and temperature measurement devices are put into motor. When the temperature is high enough or water is leaked out of motor, the device would stop running for protecting itself. In this case, safety and reliability of usage can be well guaranteed.
- The body of pump and motor use one sleeve. When submersible pump is on, this special structure will reduce attrition to sleeve, so that it is able to have a long-last service life.
- Based on national requirement on producing, our company absorbed foreign advanced water conservancy model and developed our own special technology. For now, performance of our axial flow submersible pump is still under carefully detection and experiments.
Submersible Axial Flow Pump vs Centrifugal Pump
The difference between the two kinds of pumps lies primarily on their impellers.
As name suggests, axial flow submersible pump use axial impeller. When the pump is working, large quantity of water flow towards impeller. Rapidly rotated impeller produces centripetal force, the faster impeller rotate, the stronger the force is. Centrifugal force can well promise the high capacity of outlet water. So it is suitable to be used for fiercely fluctuated water level such as lakes or river .
On the contrary, centrifugal pump uses a totally different impeller. It is well designed. When water comes towards impeller, rapidly rotated impeller gives water centrifugal force, making water flow sequentially on the edge. Impeller can be well protected for seldom water flows near it. It is mostly used for sewage water, so that impurities or erosive fluid will be far away from impeller.

Design of Submersible Axial Flow Pump
A pump usually consists of four main parts, submersible pump motor, inlet, outlet, and impeller. Motor of this kind of pump is water filled, placed at the bottom, in order not to be burnt for long time working. Inlet and outlet is quite large, thus more water can be primed without obstacle. Submersible flanges are used to connect with outlet for drainage.
Usually two to six impellers are installed inside pump body, each of them is of open style. Impellers are designed twisted as propeller. When water comes near impeller, rapidly rotated impeller results in strong thrust, pushing water flow alongside axial direction .
According to installation angle, impeller of this kind can be divided into three types. One is fixed, one is half adjustable, the other is totally adjusted. We all know that installation angle of impeller affects head and water yield. So when buying such kind of pump, APK will help adjusting impeller angle for you after knowing your needs.
Division of single stage and multistage relies on impeller numbers. If one impeller is installed, it refers to single stage pump. Or it is multistage pump. No water needs to be added when pump is working.
