Axial Flow Screwcentrifugal Pump

 
The LS201.043.0055 dry vertical helical centrifugal pump is a type of helical centrifugal pump with a vertically arranged pump shaft, and its motor and bearing parts are located above the liquid surface, in a dry environment. It goes deep into the liquid through a long shaft and drives the spiral centrifugal impeller located at the bottom of the pump body to work.

Features

The vertical spiral centrifugal pump inherits all the advantages of the spiral centrifugal impeller pump and can efficiently transport the medium containing large particles and long fibers. The motor is completely exposed to the air, providing excellent heat dissipation conditions and will never be submerged, thus avoiding the risk of the submersible pump motor burning out easily.

The vertical structure makes the foundation occupy a very small area, which is very suitable for pump pits or water tanks with limited space. When inspecting the motor, upper bearing and top mechanical seal, there is no need to lift the entire heavy-duty pump set out of the deep pit as with submersible pumps. It only needs to be operated from the top, which greatly saves manpower and time. By adjusting the length of the long shaft, it is easy to adapt to different submersible depths, and the efficiency of the pump will not be significantly affected by the head as in submersible pumps.

The dry vertical helical centrifugal pump achieves an excellent balance among floor space, deep pit suitability and maintenance convenience. It significantly enhances the reliability of long-term operation by placing the vulnerable motor in the dry zone, while addressing the issues of space and depth through a vertical structure. Although its long shaft and shaft seal system bring specific maintenance considerations, it remains one of the most mainstream and reliable choices in medium and large-scale sewage and stormwater lifting projects.


Application

  • Municipal sewage lifting pump station: This is its most classical application scenario, especially the main pump.

  • Industrial wastewater tank: Lifting and transporting wastewater from deep pits within factories.

  • Rainwater drainage pumping station: In situations where large flow drainage is required.

  • Wastewater treatment plant: influent pump room, return sludge pump, etc.

  • Flood control and drainage: Large vertical pumping station.


When you need deep pit transportation (such as sewage lift stations) and hope that the motor is easy to maintain and more reliable than submersible pumps. It is the mainstream choice for large pumping stations.
