Sewage pumping is normally done by a submersible pump.
详细介绍：
OVERVIEW:
This became popular in the early 1960s, when a guide-rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit. Growth of the submersible pump for sewage pumping since has been dramatic, as an increasing number of specifies and developers learned of their advantages.
Vertical type sewage pumps have also been used for many years. They have the motor above the floor so work on the motor can be done without entering the sewage pit.
CONDITION OF USAGE:
1, The maximum deep it is allowed in water is 5m from its center of impeller;
2, The trans medium''''s temperature shouldn''''t be higher than 40.
3, Trans medium''''s pH: 4~10;
4, Kinematics viscosity of the Trans medium''''s: 7*10-7 ~23*10-6 m2/s
5, Density of the Trans medium Limit: 1.2*103 kg/m3
FUNCTION AND FEATURE:
The letter "V" which substitutes for the letters "WQ" indicates the distinct design of the filter and the broadness of the high efficient area. It can work safely and efficiently at high flux with the feature of complete heads. The design is designed to a wide tunnel which helps to convey the long fiber liquid or the solid whose diameter is about 15mm. The selection of bottom suction structure, stainless steel and special cast iron made the pump have the capabilities of complete drain and high resistance of abrasion and corrosion. The float switch can automatically control on and off with the change of the liquor level. The protector in the motor can automatically cut off the power when it overheated or overcorrected thus guarantee the security and reliability of pump''''s run even in the atrocious environment.
