QZ and QH series submersible axial/mixed flow pump are designed for places requiring large flow rate and low head (the head under 20m).
This product is an excellent replacement to the traditional axial/mixed flow pump. The motor is seamlessly integrated with the water pump and operates under water. It has a series of advantages, which are unrivaled by traditional units.
The pumps are used 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, and in irrigation works to divert water. They are suitable 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, the investment can be saved. Bacause the motor operates under the water, the civil works and the building for the pump station can be greatly reduced. With a 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 Iow noises and good cooling conditions have been achieved.
2. The pump station can also be constructed under the ground, thus preserving the landscape above the earth.
3. Using the submersible electric pump is a 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.
