    Description of the DF type horizontal multistage stainless steel anticorrosive centrifugal pump model

    DF25-50×5

    "DF" - indicates single suction, multistage, segmented anticorrosive centrifugal pump

    "25" - indicates the flow rate of the pump (m3/h)

    "50" - indicates the manometric height per stage of the pump (m)

    "5" - indicates the number of stages

     

    Type of structure of the DF type horizontal multistage stainless steel anticorrosive centrifugal pump

    　　The DF type multistage stainless steel pump is horizontally installed. Except for the DF155-30 model pump, which has a horizontal inlet direction, the inlet of the other pumps is vertical upwards. The discharge direction of all DF type multistage stainless steel centrifugal pumps is vertical upwards. The shaft seal generally uses packing seal, although it can also use mechanical seal according to user needs. Except for the DF85-67 horizontal anticorrosive stainless steel pump, which uses sliding bearings lubricated with light oil, and the DF155-67 pump, which uses rolling bearings lubricated with light oil, the others use rolling bearings lubricated with grease. The axial force of the shaft is balanced by the symmetrical arrangement of the impeller in the DF3-40Ⅱ pump, while in the others, a balance disc is used.

     

    Structural characteristics of the DF type horizontal multistage stainless steel anticorrosive centrifugal pump

    The DF type anticorrosive stainless steel multistage pump adopts a multistage centrifugal pump structure type D, divided into four parts: static part, rotating part, sealing part, and bearing part.

    1. Static part:

    Composed of the pump body (inlet and outlet sections, middle section), guide vanes, etc., fixed by rods and screws, forming a sealed working chamber.

    2. Rotating part:

    Composed of shaft, impeller, shaft sleeve, and balance disc device, which rotates the impeller to generate centrifugal force and thus drive the flow of the medium through the transmission of the shaft.

    3. Bearing part:

    Composed of the bearing body, the bearing, and the bearing cover; the bearing supports the shaft and ensures its stable and normal operation.

    4. Sealing part:

    Divided into packing seal and mechanical seal. The packing seal is mainly used in situations where leakage requirements are not strict or when the medium contains solid particles. The mechanical seal is suitable for high temperature, high pressure, and corrosive conditions, with strict leakage requirements. Both seals ensure sealing at both ends of the pump, preventing medium leakage and ensuring the pump's tightness.

     

    Direction of rotation of the DF type horizontal multistage stainless steel anticorrosive centrifugal pump

    　　The direction of rotation of the DF type stainless steel multistage centrifugal pump, viewed from the motor end, is clockwise.

     

    Main materials of the parts of the DF type horizontal multistage stainless steel anticorrosive centrifugal pump

    　　The materials of the flow passage parts of the DF type horizontal multistage stainless steel centrifugal pump include cast steel and cast stainless steel (304, 316, 316L, 2205, 2507, etc.). When ordering, the material of the pump, the type of sealing, and the structure of the pump should be reasonably selected according to the name of the transported medium, concentration, inlet pressure, operating temperature, and degree of corrosion of the material.

     

    Scope of supply of the DF type horizontal multistage stainless steel anticorrosive centrifugal pump

    　　The pump is supplied along with the motor and base, which can be equipped with a common base or its own base. The multistage pump manufacturer Zhonglian also offers accessories (including conical discharge pipe, gate valve, check valve) and spare parts (including impeller, sealing ring, guide sleeve, balance disc, shaft sleeve).

    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 。
