The vertical long-shaft pump for agricultural irrigation is a type of agricultural water pump. There are many different types of agricultural water pumps, and the vertical long-shaft pump, as an agricultural irrigation pump, boasts unique advantages: it does not require a separate vacuum pump to create a vacuum beforehand. As a vertical pump, it occupies a smaller footprint, has a simple and rational structure, and is easy to maintain and service.

· The significance of model designations for vertical long-shaft pumps used in agricultural irrigation
200LC-23A×2-LH
200——The pump outlet diameter is 200 mm.
LC—Vertical Long-Shaft Pump for Agricultural Irrigation
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 as follows: 100LC50-20Ax2-L and 150LC140-15Ax2-L, where 50 and 140 represent the pump’s design-point flow rate. For vertical long-shaft pumps with calibers ranging from 200 to 1000, the model formats do not include flow-rate parameters.
· Structural Description of Vertical Long-Shaft Pumps for Agricultural Irrigation
The structural types of vertical long-shaft pumps for agricultural irrigation 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 lubricating water is supplied versus self-lubrication by the pump itself. As for pump installation methods, there are wet-pit installations and dry-pit installations.
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 suction bellmouth of the pump is connected to the inlet pipe 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 typically of a non-removable type. The axial water thrust and the rotor weight are generally 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. 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 of the mounting surface. If required, the pump itself can also bear the axial water thrust and the rotor’s weight, or a combination of other structural configurations may be adopted. 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 agricultural irrigation is subjected to axial water thrust and rotor weight, the pump thrust bearing is lubricated with thin oil. The thrust bearing components are equipped with Pt100 temperature sensors to measure bearing temperature, or pressure-type thermometers to measure lubricating oil temperature. The pump features a packing seal for axial shaft sealing. 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 lubrication 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.
