    Product Parameters

    Working Parameters and Model Meaning of IRG Vertical Hot Water Pipeline Centrifugal Pump:

    　　1. The maximum working pressure of the IRG hot water pipeline pump system is ≤1.6Mpa, and the pump static pressure test pressure is 2.5Mpa. Please specify the system working pressure when ordering. If the pump system working pressure is greater than 1.6Mpa, it should be specified when ordering so that cast steel materials can be used for the pump flow and connection parts during manufacturing.

    Meaning of ISG Type Hot Water Pipeline Pump Model

    Applications of IRG Vertical Hot Water Pipeline Centrifugal Pump:

    　　ISG type pipeline centrifugal pump is used for transporting clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire-fighting pressurization, long-distance transportation, HVAC cooling and heating circulation, bathroom hot and cold water circulation pressurization, and equipment matching, with a usage temperature T<80℃.

    　　IRG type hot water high-temperature pipeline pump is widely used in energy, chemical, textile, papermaking, hotels, and other boiler high-temperature hot water pressurization circulation transportation and urban heating system circulation pumps. The IRG type has a usage temperature T<120℃. The GRG type hot water high-temperature pump has a usage temperature T<240℃.

    　　IHG vertical chemical pipeline pump is used for transporting liquids without solid particles, corrosive, and with viscosity similar to water. It is suitable for petroleum, chemical, metallurgy, electric power, papermaking, food and pharmaceutical, and synthetic fiber industries, with a usage temperature of -20℃ to 120℃.

    　　YG type explosion-proof centrifugal pump and vertical centrifugal oil pump are used for transporting petroleum products such as gasoline, kerosene, and diesel. The transported medium temperature is -20℃ to +120℃.

    Features of IRG Vertical Hot Water Pipeline Centrifugal Pump:

    　　1. The hot water pipeline pump has a vertical structure, with the inlet and outlet diameters being 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 of the hot water pipeline pump is directly installed on the extended shaft of the motor, with a short axial dimension and compact structure. The pump and motor bearing configuration is reasonable, effectively balancing the radial and axial loads generated during pump operation, ensuring smooth operation with low vibration and noise.

    　　3. The shaft seal of the high-temperature pipeline pump uses tungsten carbide against graphite, hard alloy, and other materials, effectively extending the service life of the mechanical seal.

    　　4. The high-temperature pipeline pump is easy to install and maintain. There is no need to dismantle the pipeline system; simply remove the pump coupling seat nut to pull out all rotor components.

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

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

    Pump Instructions:

    　　I. Preparation before starting:

    　　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. Close the exhaust valve after filling.

    　　3. Check whether all parts of the IRG vertical centrifugal pump are normal before starting.

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

    　　5. The high-temperature type should be preheated first, with a heating rate of 50℃/hour to ensure uniform heating of all parts.

    　　II. Starting:

    　　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 conditions. 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 operates 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. Stopping:

    　　1. Close the discharge pipeline valve.

    　　2. Stop the motor.

    　　3. Close the inlet valve when stopping the vertical centrifugal pump.

    　　4. If stopping for a long time, drain the liquid inside the pump.

    　　5. For high-temperature types, cool down first, with a cooling rate

    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 。
