ZQBSubmersible axial flow pump stations have rapidly developed due to their simple civil engineering, low construction cost, convenient maintenance and management, easy installation, ease of automation, high operational reliability, and environmental beautification.
Key equipment for the submersible pump stationSubmersible pump (shortened to sub-pump)QZType Submersible Axial Flow PumpQHType Submerged Mixed Flow Pump, an integrated mechanical and electrical product combining an electric motor with an axial flow pump and a mixed flow pump, serving as an upgraded and replacement for the traditional long shaft axial flow and mixed flow pumps.
Submersible pumps and traditional long shaft pumps are essentially consistent in terms of application, water intake and outlet conditions, and characteristic parameters. Advantages include:
Total investment savings in pump station project30%Above
Construction cycle savings40%Above.
Installation Time Savings for Engine Assembly95%Above.
Reduced engine weight50%Above;
Eliminate floodwall investment for pump stations.
Low maintenance costs.
Zero operation noise, easy to operate, and suitable for automated operation.
Low ground elevation allows for the elimination of a pump house building, and even the construction of a pump station below ground level.
 Therefore, users of axial flow pumps and mixed flow pumps can conveniently replace them with submersible pumps in new pump station projects, and can update them with submersible pumps in the renovation of old pump stations. Submersible axial flow pumps are mainly suitable for the following situations:
◎ Agricultural irrigation and drainage.
◎ Municipal stormwater and light industrial wastewater.
◎ Process water and cooling water for industry.
◎ Water Diversion Project in Water Conservancy
