    Product Overview

    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump This is the new generation of high-efficiency, single-stage, single-suction centrifugal pumps developed by the technical team at Changsha Zhonglian Pump Industry, a leading manufacturer of centrifugal pumps. These energy-saving pumps are the result of a nationwide collaborative design effort. They represent an upgraded model compared to the BA, BL, and other single-stage clear-water centrifugal pump series, offering several key advantages: - The entire series features a well-balanced hydraulic design, providing users with a wide range of options and ensuring convenient maintenance. - Efficiency and suction lift performance have reached internationally advanced average levels, making these pumps ideal for industrial and municipal water supply and drainage applications. They are also suitable for agricultural irrigation and drainage, as well as for conveying clean water or other liquids with physical and chemical properties similar to water—provided the liquid temperature does not exceed 80°C. 


    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump Structure Features and Advantages

    　　1 Pump body, 2 Pump cover, 3 Impeller, 4 Shaft, 5 Seal ring, 6 Impeller nut, 7 Lock washer, 8 Shaft sleeve, 9 Stuffing gland, 10 Stuffing ring, 11 Packing, 12 Suspension bearing assembly.

    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump It is designed according to the performance and dimensions specified in the national standard ISO 2858, and primarily consists of components such as the pump body (1), pump cover (2), impeller (3), shaft (4), sealing ring (5), shaft sleeve, and suspended bearing assembly (12).

    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump It features a back-opening design, allowing you to disassemble the pump cover and impeller without removing the suction and discharge pipelines. The suspension housing is equipped with two ball bearings, lubricated with machine oil or grease. The pump is directly driven by an electric motor via an elastic coupling. Meanwhile, the volute chamber, base, inlet flange, and outlet flange are integrally cast as a single unit.

    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump The pump body and the cover are split from the back of the impeller—this is what’s commonly known as the rear-opening structure. Its advantage lies in convenient maintenance: during inspections or repairs, you don’t need to move the pump body, suction piping, discharge piping, or even the motor. Instead, you can simply remove the intermediate coupling piece of the extended shaft coupling, allowing the rotor assembly to be easily withdrawn for inspection and servicing.

    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump The casing—comprising the pump body and pump cover—forms the pump's working chamber. The impeller, shaft, and rolling bearings constitute the pump's rotor. The suspension bearing assembly supports the rotor components, while the rolling bearings handle both the radial and axial forces acting on the pump.

    　　To balance the axial force of the pump, most pumps are equipped with sealing rings on both the front and back of the impeller, as well as balance holes on the back cover plate of the impeller. However, since some pumps have relatively small axial forces, no sealing ring or balance hole is provided on the back side of the impeller.

    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump The axial sealing ring consists of components such as the packing gland (9), packing rings (10), and packing material (11), designed to prevent air intake or excessive water leakage. If the pump impeller is balanced, the cavity equipped with soft packing is connected to the impeller’s suction inlet. In this case, if the liquid at the impeller inlet is under vacuum, air can easily enter along the shaft sleeve surface. To address this issue, a packing ring is installed inside the packing chamber; pressure water from the pump chamber is directed through a small hole in the pump cover to lubricate and seal the packing ring. However, if the pump impeller lacks balancing holes—resulting in higher liquid pressure on the back side of the impeller than atmospheric pressure—there will be no air leakage problem, making it unnecessary to install the packing ring altogether.

    　　To avoid IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump Axle wear is addressed by installing an axle sleeve for protection at the point where the shaft passes through the stuffing box. An O-ring seal is fitted between the sleeve and the shaft to prevent air or water leakage along the mating surfaces.

    IS-Type Horizontal Single-Stage Centrifugal Clear Water Pump The transmission method is achieved by connecting the motor via an extended flexible coupling. When viewed from the drive end, the pump rotates clockwise.

    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 。
