The vertical long-shaft pump for flood control and drainage, also known as a vertical long-shaft turbine pump, is primarily used for drainage operations during the flood season. It can also be employed to convey clean water, sewage containing certain solid particles (such as iron filings, sand grains, coal dust, etc.), corrosive industrial wastewater, and seawater. The temperature of the liquid being conveyed should not exceed 90℃.

Product Parameters
· Product advantages of vertical long-shaft flood control and drainage pumps/vertical long-shaft turbine pumps
1. Smooth operation, safe and reliable, no need for vacuum pumping at startup, and a long service life.
2. The pump is compact in size and requires a small footprint. The length of the pump below the foundation is adjustable, making it highly adaptable.
3. The flow path is simple and reliable, saving on capital investment for pump room construction.
4. The structure is reasonable, easy to assemble and disassemble, and simple and convenient for maintenance and inspection.
5. The pump boasts high efficiency, reducing operating costs.
· Significance of Model Designations for Vertical Long-Shaft Flood Control and Drainage Pumps/Vertical Long-Shaft Turbine Pumps
200LC-23A×2-LH
200——The pump outlet diameter is 200 mm.
LC—Flood Control and Drainage Vertical Long-Shaft Turbine Pump
23—When the impeller is not cut, the single-stage design head of the pump is 23 m (total pump head = single-stage head × number of impeller stages).
A—Impeller outer diameter cutting code
×2—The impeller has 2 stages (omitted when the stage number is 1).
L Submerged depth (Lw40m, unit: m)
H—Pump with protective casing (omit if no protective casing is used).
Note: The model formats for 100-caliber and 150-caliber pumps are 100LC50-20Ax2-L and 150LC140-15Ax2-L, respectively, where 50 and 140 represent the pump’s design-point flow rate. For vertical long-shaft pump models with diameters ranging from 200 to 1000, the flow-rate parameter is not included in the model format.
· Structural Description of Vertical Long-Shaft Flood Control and Drainage Pumps/Vertical Long-Shaft Turbine Pumps
The structural types of vertical long-shaft pumps for flood control and drainage include configurations where the pump discharge outlet is located above or below the installation base, where the pump itself bears axial forces while the motor bears axial forces, and where external lubrication water is supplied versus self-lubrication by the pump itself. Pump installation types include wet-pit installation or dry-pit installation.
Wet-pit installation: The pump’s lower part is submerged in the suction basin.
Dry-pit installation: The pump is supplied with water via a pipeline, and the connection between the pump’s suction bellmouth and the inlet pipe is made using a 90° elbow-shaped inlet bend. The pump bearings are either rubber guide bearings or ceramic guide bearings.
When the pump bore diameter is 1000 mm or less, the pump rotor is generally of a non-removable type. The axial water thrust and the rotor weight are typically borne by the thrust bearings housed within the pump body itself. An elastic coupling is used between the pump and the motor. The pump discharge outlet is located above the mounting surface base. If required, the motor can also be designed to bear the axial water thrust and rotor weight, or a combination of other structural configurations may be adopted. Should the user have specific requirements, the pump can also be designed with a removable rotor structure.
When the pump diameter exceeds 1000 mm, the pump rotor is typically designed with a withdrawable configuration. The axial water thrust and the rotor’s weight are generally borne by the motor’s thrust bearing. A rigid coupling is used between the pump and the motor, and the pump’s discharge outlet is located on the base surface of the installation platform. If required, the pump itself can also be designed to bear the axial water thrust and the rotor’s weight, or a combination of other structural configurations. Should the user have specific requirements, the pump can also be designed in a non-withdrawable configuration.
When the pump body of the vertical long-shaft pump for flood control and drainage is subjected to axial water thrust and rotor weight, the pump thrust bearing is lubricated with diluted oil. The thrust bearing components are equipped with Pt100 temperature sensors to measure bearing temperature, or pressure-type thermometers to measure lubricant oil temperature. The pump’s axial seal employs a packing seal. On the pump mounting base, the clearance between the impeller and the impeller chamber (between the rotating and stationary parts) can be easily adjusted, making operation convenient. When viewing the pump from the discharge direction, the motor junction box and the external lubricating water pipe connection are located on the left side. Alternatively, they can be arranged in other positions according to user requirements.

Q
What is your typical delivery time?
A
Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。
Q
Do you have centrifugal pumps in stock?
A
Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.
Q
What information should I provide when requesting a quote?
A
Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.
If you are not sure, don't worry, our business managers will assist you in determining this.
Q
What products do you mainly produce?
A
Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.
Q
Why is it so slow to get a price quote?
A
Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
