Product Description
Axial-Flow/Mixed-Flow Submersible Sewage Pump
The QZB series of submersible axial-flow pump is a kind of electromechanical product featuring an integration of motor and mixed flow pump. It has replaced the traditional dry type mixed-flow pump and has been one of main equipments in submersible pump station. At the same time, submersible pump station has been developing rapidly due to easy civil engineering, low project cost, convenient maintenance, simple installation and other advantages.
There are some features in this pump:

The total amount of investment in the pump station will be reduced by over 30%;
The period of construction can be shortened by over 40%;
The unit installation time will be saved by about 95%;
Investment in pump station flood control wall is omitted;
Lower maintenance expenses.
In view of the above, the pump is fit for the following cases:
Rainwater and light sewage discharged by municiple works;
Water transfer projects in water servancy;
Industrial processing and cooling water;
Farmland irrigation and drainage.
