    Structure Diagram and Features of ISG Vertical Single-Stage Single-Suction Pipeline Centrifugal Pump:

     

    1. The ISG vertical pipeline pump has a vertical structure, with the inlet and outlet diameters the same and located on the same centerline. It can be installed in the pipeline like a valve, with a compact and beautiful appearance, small footprint, and low construction investment. With a protective cover, it can be used outdoors.

    2. The impeller is directly mounted on the motor's extended shaft, with a short axial dimension and compact structure. The pump and motor bearing arrangement is reasonable, effectively balancing the radial and axial loads generated during pump operation, ensuring smooth operation, low vibration, and low noise.

    3. The shaft seal uses mechanical seals or combinations of mechanical seals, with imported titanium alloy sealing rings, medium high-temperature mechanical seals, and hard alloy wear-resistant seals, effectively extending the service life of the mechanical seal.

    4. Installation and maintenance are convenient without dismantling the pipeline system. The entire rotor assembly can be pulled out by simply removing the pump coupling seat nuts.

    5. The ISG vertical pipeline centrifugal pump can operate in series or parallel according to flow and head requirements.

    6. The ISG vertical pipeline centrifugal pump can be installed vertically or horizontally according to pipeline layout requirements.

     

    Pipeline Pump Preparation, Start-up, and Shutdown:

    I. Preparation before Start-up:

    1. Test whether the motor rotation direction is correct. Viewed from the top of the motor towards the pump, it should rotate clockwise. The test time should be short to avoid dry wear of the mechanical seal.

    2. Open the exhaust valve to fill the entire pump body with liquid, then close the exhaust valve after filling.

    3. Check whether all parts of the ISG single-stage pipeline pump are normal before starting.

    4. Manually rotate the pump to allow lubricating liquid to enter the mechanical seal end face.

    5. High-temperature types should be preheated first, with a heating rate of 50℃/hour to ensure uniform heating.

    II. Start-up:

    1. Fully open the inlet valve.

    2. Close the discharge pipeline valve when starting the vertical centrifugal pump.

    3. Start the motor and observe whether the pump operates correctly.

    4. Check the shaft seal leakage; under normal conditions, mechanical seal leakage should be less than 3 drops per minute.

    5. Check that the temperature rise at the motor and bearing is ≤ 70℃.

    6. Adjust the outlet valve opening according to the required working condition. If the user installs a flow meter or pressure gauge at the pump outlet, adjust the outlet valve opening so that the pump operates at the rated point listed in the performance parameter table. Also, measure the motor current to ensure it runs within the rated current; otherwise, the pump will be overloaded (i.e., high current operation), causing motor burnout. The optimal outlet valve opening depends on pipeline conditions.

    III. Shutdown:

    1. Close the discharge pipeline valve.

    2. Stop the motor.

    3. Close the inlet valve when shutting down the vertical centrifugal pump.

    4. For long-term parking, the liquid inside the pump should be drained completely.

    5. For high-temperature types, cool down first; cooling speed

     

    Maintenance during operation and mechanical seal maintenance:

    I. Maintenance during operation:

    1. The inlet pipeline must be filled with liquid; it is forbidden for the pump to run long-term under cavitation conditions.

    2. The vertical pipeline centrifugal pump should have the motor current checked regularly and must not exceed the motor's rated current.

    3. After long-term operation, due to mechanical wear, if noise and vibration increase, stop the pump for inspection. Replace worn parts and bearings if necessary. The general major overhaul period is one year.

    4. During operation, there should be dedicated personnel for management and maintenance to prevent accidents.

    5. Bearings should be lubricated every 500 hours of operation. Motors over 11KW are equipped with lubrication devices and can be directly injected with a high-pressure oil gun to ensure good bearing lubrication.

    II. Mechanical seal maintenance:

    1. The mechanical seal lubrication during pump use should be clean and free of solid particles.

    2. It is strictly forbidden for the mechanical seal of vertical centrifugal pumps to operate under dry friction conditions.

    3. Before starting the pump, manually rotate the pump (motor) several turns to avoid sudden start causing graphite breakage or damage.

    4. The allowable leakage of the seal is 3 drops per minute. Otherwise, inspection is required.

    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?

    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.
