    　　Direction of rotation of the single-stage chemical pump with simple suction: viewed from the suction inlet towards the motor, it rotates clockwise.

    　　The single-stage chemical pump with simple suction and the motor are mounted on the same base via an elastic coupling.

    　　The sealing device of the shaft of the single-stage chemical pump with simple suction uses a new pressure-reducing structure through the impeller and double-sided mechanical seal, the sealing chamber is filled with high-quality lubricating grease and has an oil cup.

     

    Use of the product of the single-stage centrifugal chemical pump with simple suction type BF resistant to corrosion

    　　The corrosion-resistant chemical pump type FB is widely used in the sectors of chemistry, petroleum, metallurgy, light industry, synthetic fibers, environmental protection, food, pharmaceuticals, among others. This type of product uses a double-sided mechanical seal to improve product quality, reduce leaks, drips, and escapes, prevent contamination, improve the environment, and play an important role. It has the advantages of stable and reliable performance, good sealing, attractive design, and easy maintenance.

     

    Installation and disassembly of the corrosion-resistant chemical pump

    　　1. Before installing the mechanical seal, check if all components are damaged. If there is damage, they must be repaired or replaced.

    　　2. Strictly inspect the friction surfaces of the moving ring and the static ring, there should be no scratches or collisions. Before assembly, apply a layer of clean oil on the surfaces of the moving and static rings.

    　　3. During assembly, pay attention to eliminate deviations and correctly adjust the compression of the spring so that it is neither too loose nor too tight. When tightening the screws, do it evenly to avoid tilting that may cause sealing failures.

    　　4. When disassembling, pay attention to the order of disassembly of the pump.

     

    Instructions for use of the corrosion-resistant chemical pump

    　　Starting:

    　　1. Prepare the necessary tools and transport devices.

    　　2. Check if the lubricating grease in the oil cup of the sealing device is full.

    　　3. Check that the direction of rotation of the corrosion-resistant chemical pump is correct; reversing the rotation is strictly prohibited. Incorrect rotation can loosen the impeller nut, allow corrosive medium to enter the shaft neck causing corrosion, which may prevent the pump from operating and can also cause the impeller nut to fly off causing accidents. Before starting the pump, secure the coupling cover to ensure safety.

    　　4. If the installation position of the pump is below the liquid level (backflow situation), before starting the pump, open the gate valve of the pipe to fill the pump with liquid. If the installation position is above the liquid level (vacuum situation), before starting the pump, prime the pump and purge to fill the pump and the suction pipe with liquid and remove the air.

    　　5. After starting the motor, slowly open the outlet gate valve; when the pump is operating normally, open the valve to the necessary degree.

    　　Stopping:

    　　1. Close the gate valve of the pressure pipe.

    　　2. Stop the motor.

    　　3. Close the gate valve of the suction pipe.

    　　4. When the ambient temperature is below the freezing point of the liquid, completely drain the liquid stored in the pump.

    　　5. If the corrosion-resistant chemical pump will be out of service for a long period, it must drain the corrosive medium inside the pump, rinse with clean water, and after cleaning, store it properly.

    　　Operation:

    　　1. The temperature of the pump and the motor must be checked frequently, mainly the bearing temperature, which should not exceed 73℃.

    　　2. During operation, if abnormal noises or sounds are detected, it must be stopped immediately for inspection and to eliminate faults before continuing.

    　　3. Pay attention to the oil cup of the sealing device, maintain the oil storage, and replenish in time to ensure lubrication.

    　　4. The mechanical seal is used in clean media without suspended particles. Therefore, special attention must be paid to cleaning the pipes in new systems.

    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 。
