    The XBD-LC vertical long-shaft fire pump is a motor that drives the rotation of the submerged impeller through the shaft. The fluid gains energy from the impeller and then changes direction through the spatial guide vanes. Then, it rises vertically through the flow channel between the inner and outer tubes, and finally exits horizontally through the outlet elbow.

    Product description

    The vertical long shaft fire pump XBD-LC is a motor that drives the rotation of the submerged impeller through the shaft. After the fluid gains energy through the impeller, the direction is changed through the spatial guide vanes, rises vertically along the flow channel between the inner and outer tubes, and then exits horizontally through the discharge elbow.

    Long shaft fire pump


    The vertical long shaft fire pump XBD-LC consists of a rotating part and a pump body. The rotating part is composed of the impeller, shaft, rigid sleeve-type coupling (coupling and sleeve), bearing, elastic pin coupling, etc. The pump body part is composed of a filter screen, spatial guide vanes, outer tube, inner tube, rubber bearing support, base, discharge elbow, bearing body, motor support, etc.

    The entire part of the vertical long shaft fire pump XBD-LC is connected to the discharge elbow and fixed to the bottom plate. The upper double roller bearings of the rotating part and the intermediate guide bearing components are connected to the discharge elbow and fixed to the bottom plate. The upper double roller bearings of the rotating part, the intermediate guide bearing components, and the lower guide bearing components inside the spatial guide vanes provide support.

    At the same time, clean lubricating water (the inner tube can be omitted when the medium is clean water) is injected through the lubricating water inlet pipe on the stuffing box side, continuously lubricating and cooling the guide bearing (PFC) along the flow channel between the inner tube and the shaft. This is the key for the vertical long shaft fire pump XBD-LC to operate normally under adverse conditions, such as transporting media containing solid particles.

    Product parameters

    · Meaning of the long-shaft vertical fire pump model

    200XBD-LC-23A×2-LH

    200——The outlet diameter of the water pump is 200 mm

    XBD-LC——Long-shaft vertical fire pump

    23——The design height of a single stage of the water pump when the impeller is not trimmed is 23 m (total height of the water pump = single stage height × number of impeller stages)

    A——Impeller outer diameter trimming code

    ×2——The number of impeller stages is 2 (omitted if the number of stages is 1)

    L Immersion depth (Lw40m, unit: m)

    H——Water pump with protective tube (omitted if no protective tube).

    Note: The model format for diameters 100 and 150 is 100XBD-LC50-20Ax2-L. 150XBD-LC140-15Ax2-L, where 50 and 140 represent the design flow of the water pump. The model format for the long-shaft vertical pump with diameters from 200 to 1000 mm does not include the flow parameter.

     

    · Structural features of the long-shaft vertical fire pump

    The inlet of the XBD-LC long-shaft vertical fire pump is oriented vertically downward, the outlet is horizontal, it starts without the need for vacuum, is installed on a single base, the pump and motor are directly connected, the base occupies a small area; viewed from the motor end, the pump rotor parts rotate counterclockwise, the main structural features are:

    1. Advanced hydraulic engineering models and designs are introduced, multiple new technologies are adopted, such as Ashland technology core, epoxy coating on the blade passage parts, etc., which can withstand high temperatures of 120 degrees. A Borgmann mechanical seal is used, durable, acid and alkali resistant, highly efficient, and long-lasting.

    2. A sand removal ring device is used, the labyrinth structure prevents sand grains from entering the bearing.

    3. A one-piece seamless cast stainless steel flow impeller is used, with an anti-winding and unobstructed design. The pump shaft is precision-machined stainless steel, radial shaft vibration is controlled within the international standard of 0.13 mm, the pump operates stably and noise is low.

    4. Corrosion-resistant materials of various stainless steel grades are selected, such as QT450 and HT250 ductile iron castings, to meet various special usage conditions and technical requirements of users.

    5. High product efficiency, the pump head is fully submerged in the liquid, no self-priming time, the pump supplies water under pressure simultaneously at startup.

    6. The pump impeller is submerged in water, no foot valve, no need for priming or shaft vacuum, can start directly, very convenient and reliable.

    7. It is installed directly on the water tank, only two support beams and U-shaped steel beams are needed for fixing, no suction pipes required.

    8. The maximum immersion and suction height of the pump can reach about 10 meters, vertical structure, small footprint, low construction investment.

    9. The immersion length can be customized according to the depth of the water tank to ensure pumping to the lowest water level.

    FAQ

    Q

    What products do you mainly produce?

    A

    Zoomlion Pump Industry manufactures various large industrial centrifugal pumps. The main products include: self-balancing multistage pumps, multistage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condenser pumps, and more.

    Q

    Can you help me choose a model?

    A

    Of course! If the water pump model is not selected accurately, it can cause significant problems. After you take it back, it might be either too small to meet the usage requirements or too large, resulting in higher electricity and fuel costs, increasing the operating expenses.

    Q

    Why is the price quotation so slow?

    A

    Because centrifugal pumps are non-standard custom products with many models and a wide price range. Even for the same model, the price varies greatly depending on the materials and configurations used. Taking the most common 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 clearly confirm the relevant information to provide you with an accurate price. Normally, if you provide comprehensive information, we can quote within 5 minutes.

    Q

    What information should I provide when I need a quote?

    A

    Usually, if you want to get an accurate quote, it is recommended that you provide us with the following information: pump flow rate, head, on-site operating voltage, frequency, temperature of the conveyed liquid, pH value, solid particle content, on-site installation conditions (horizontal or vertical installation), and other related details. If you are not very familiar with these, it’s okay; our sales manager will assist you in determining them.

    Q

    Do you have centrifugal pumps in stock?

    A

    There are many models and configurations of centrifugal pumps. Except for a small number of commonly used standard models that are in stock, the vast majority of models and configurations are not stocked and are customized products. We need to first select the pump based on your site conditions such as flow rate, head, medium temperature, pH value, and installation conditions. After determining the pump model and configuration, we can then place an order with the workshop for production.

    Q

    What is your usual delivery time?

    A

    Models in stock can be shipped by the next day at the latest. Others are custom-made, and depending on the product size and specific project conditions, the delivery time is generally between 7-90 days. Please consult our sales manager for details: 0731-88632200 。
