    Preparation before starting the corrosion-resistant stainless steel pipe pump
    1. Verify that the motor rotation direction is correct; viewed from the top of the motor towards the pump it should rotate clockwise. The test should be brief to avoid wear on the mechanical seal.
    2. Open the purge valve to fully fill the pump body with liquid, then close the purge valve.
    3. Check that all parts are in normal condition.
    4. Manually rotate the pump so that the lubricant enters the surface of the mechanical seal.

    5. The explosion-proof stainless steel pipe pump for high temperature must be preheated first, with a temperature rise rate of 50°C/h to ensure uniform heating.

    Start-up

    1. Fully open the inlet valve.
    2. Close the discharge pipe valve.
    3. Start the motor and observe if the pump operates correctly.
    4. Adjust the outlet valve opening according to the required conditions. If the user has a flow or pressure meter at the pump outlet, the valve should be adjusted so that the pump operates at the nominal point according to the performance parameter table. If there is a flow or pressure meter, the motor current should be measured and the valve adjusted so that the motor operates within the nominal current, avoiding overload (high current) that could burn the motor. The correct outlet valve opening depends on the pipe conditions.
    5. Check the shaft seal leakage; normally the mechanical seal leakage should be less than 3 drops per minute.
    Check that the temperature rise in the motor and bearings is ≤70°C.

    Stop
    1. For high temperature models, cool down first; the cooling rate should be <10°C per minute, lowering the temperature to less than 80°C before stopping.
    2. Close the discharge pipe valve.
    3. Stop the motor.

    4. Close the inlet valve.
    5. If stopping for a long time, completely drain the liquid inside the pump.


    Special notes for the corrosion-resistant stainless steel pipe pump
    Water pumps under 7.5kW can be installed directly on the base with anti-vibration pads.
    For powers above 7.5kW, it can be installed directly with the cast base, or use the IS connection plate from our unit along with the seismic isolator; the installation method of the seismic isolator is the same as that of the isolator compatible with the ISG pump, and the isolator dimensions are the same as those of the water pump isolator of the same specification in the ISG series.

    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 。
