Vertical Type Submersible Axial Flow Pump

  • 380V  660V  3KV  6KV  10KV 

  • 7.5KW~630KW 

  • 2~20m 

  • 350~1600mm 

The QZB (QHB) series of submersible axial-fow (mixed-flow) pumps are electromechanical products featuring an integration of motors and axial-low or mixed-fow pumps and are pumps replacing the traditional dry type axia-flow and mixed-fow pumps. They constitute the main equipment of a submersible pump station. Submersible pump stations have been developing rapidly due to easy civil engineering, low project cost, convenient maintenance, and management, simple installation, easy automation, a high degree of operating reliability, and environmental beautification.

QZ series submersible axial flow pump and QH series submersible mixed flow pump is designed for places requiring large flow rates and lower head. Generally, the submersible axial flow pump is used for the head under 10 m while the submersible mixed flow pump is for the head under 20 m. This product is an excellent replacement for the traditional axial flow pump and mixed flow pump. The motor is seamlessly integrated with the water pump and operates underwater.

These pump have a series of advantages, which are unrivaled by traditional units as below:

- The total investment in pumping station projects will be saved by more than 30%

- Construction cycle savings of more than 40%

- The unit installation time of the pump will be saved more than 95%

- The weight of the pump unit is reduced by more than 50%

- No investment in flood walls at pumping stations

- Low maintenance cost

- No running noise, easy to operate, easy to automate

The QZB (QHB) series of submersible axial-flow (mixed-flow) pumps are mainly used in large and medium-sized submersible pump stations and are electromechanical products featuring an integration of motors and axial-flow or mixed-flow pumps and are pumps that replace the traditional long-axis axial-flow and mixed-flow pumps.

Applications and Features


- In agriculture to irrigate and drain water

- In municipal works to drain rainwater and slightly polluted water

- In industries to supply process water, cooling water and raw water

- In irrigation works to divert water

- In water conservancy to transport clean water or slightly polluted water


1. The motor and the water pump are an integral part. There is no need to perform the complicated axial alignment, which costs time and work. So it is very simple and easy to install.

No space reserve is needed for the standby pump. By storing the standby pump into the storehouse, investment can be saved. Because the motor operates under the water, the civil works and the building for the pump station can be greatly reduced. With reduced installation area, 30 - 40% of the total price for the pump station can be saved.

The pump operates under the water and the water flows around the motor. So low noises and good cooling conditions have been achieved.

2. The pump station can also be constructed under ground,thus preserving the landscape above the earth.

3. Using the submersible electric pump is the thorough solution to solve the challenge of pump station construction and flood prevention at rivers and lakes,where the water level has a large fluctuation. In this way,the long shaft has been saved between the motor and the pump,and the safety and reliability improved.
