    Installation and Operation Instructions for AZ Type Chemical Corrosion-Resistant Pulp Slurry Pumps

    1. Installation

    1. Before installation and use, please carefully read the "Installation, Use, and Maintenance Manual"

    2. The weight of the pipeline must be supported separately; the pump must not bear the weight or other torque of the pipeline.

    3. The amount of #46 lubricating oil should be controlled between the two oil level lines in the oil window. Lubricating oil needs to be replaced every 1500 hours of operation.

    4. For newly installed reform routes and storage tanks, flush thoroughly to prevent solid substances from entering the mechanical seal, which would affect sealing performance and lifespan.

    2. Starting and Stopping

    1. Preparation before starting

    a. Manually rotate the impeller; it should rotate smoothly without jamming or grinding.

    b. Open the inlet valve, close the outlet valve, and expel air from the pump to fill it with liquid.

    c. Manually turn the pump to allow lubricating liquid to enter the mechanical seal faces.

    d. Jog the motor to confirm the rotation direction is correct.

    2. Starting and running

    a. Fully open the inlet valve and close the outlet pipeline valve.

    b. Connect the power supply; after the pump reaches normal speed, gradually open the discharge pipeline valve and adjust to the required operating conditions.

    c. Observe instrument readings and check for shaft seal leakage. Normally, mechanical seal leakage should be less than 3 drops per minute. Check motor bearing temperature rise ≤70°C. If abnormalities occur, stop immediately and inspect the cause.

    3. Stopping

    a. Gradually close the discharge pipeline valve and cut off the power supply.

    b. Close the inlet valve.

    c. If the ambient temperature is below 0°C, drain the liquid inside the pump to prevent freezing damage.

    d. For long-term shutdown, disassemble, clean, and package the pump for storage.

    3. Pump Maintenance and Care

    1. Maintenance and care during operation

    a. The water inlet pipeline must be tightly sealed without water or air leaks.

    b. It is forbidden for the pump to operate under cavitation conditions for extended periods.

    c. It is forbidden for the motor to run overcurrent for long periods under high flow conditions.

    d. Regularly check the motor current during pump operation to keep the pump running within the design operating range.

    e. The pump should be monitored by dedicated personnel during operation to prevent accidents.

    f. The pump bearings should be lubricated every 500 hours of operation.

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

    h. If faults occur during operation, refer to the troubleshooting methods provided in the following table. If unresolved, do not disassemble the unit arbitrarily; contact our company's maintenance department or authorized service points promptly.

    2. Mechanical Seal Maintenance and Care

    a. Mechanical seal lubrication should be clean and free of solid particles.

    b. It is strictly forbidden for the mechanical seal to operate under dry grinding conditions.

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

    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 。
