    Product Description

    The submersible sludge pump type WQ(QW) is a new generation product developed based on the introduction of advanced foreign technology, combined with the usage characteristics of domestic water pumps. It features high energy efficiency, unique structure, anti-clogging, no blockages, automatic installation, and automatic control. It has a unique effect in transporting solid particles and long fiber waste. It is suitable for the chemical, petroleum, pharmaceutical, mining, paper, cement factories, steel mills, power plants, coal processing industry, as well as for drainage systems of urban wastewater treatment plants, municipal engineering, construction sites, and other sectors to transport wastewater and waste with ribbon-like particles. It is also used for pumping clean water and corrosive media.

    Submersible Sludge Pump Type WQ(QW)

    The submersible sludge pump type WQ(QW) uses a unique impeller structure and a new mechanical seal, which can effectively transport solids and long fibers. Compared to traditional impellers, the impeller of this pump adopts a single or double channel shape, similar to a curved tube with the same cross-section, providing excellent flow. Combined with a reasonable volute chamber, this pump has high efficiency. The impeller has passed dynamic and static balance tests, ensuring the pump operates without vibrations.

    Product Parameters

    Usage conditions and description of the WQ(QW) type submersible sludge pump model:

    1. The medium temperature for the WQ(QW) type submersible sludge pump should not exceed 60℃; the medium density is 11.3kg/dm3

    2. For pumps without an internal circulation cooling system, the exposed part of the motor should not exceed 1/3 above the liquid surface
     

    3. The usage range of the cast iron material is PH59

    4. The stainless steel material 1Cr18Ni9Ti is suitable for general corrosive media.

    5. The altitude of the usage environment should not exceed 1000 meters.

    If the user has special temperature or medium requirements, please specify the details of the transported medium when placing the order so that our unit can provide a more reliable product.

    15 - flow rate (m3/h)

    30 - lift height (m)

    2.2 - motor power (kw)

    Main features of the WQ(QW) type submersible sludge pump

    1. The WQ(QW) type submersible sludge pump uses a unique single or double blade impeller structure, which significantly improves the waste passage capacity, effectively passing fibers five times the pump diameter and solid particles approximately 50% of the pump diameter.

    2. The mechanical seal uses a new hard and corrosion-resistant tungsten carbide material, and the seal has been upgraded to a double-sided seal, allowing continuous operation in the oil chamber, ensuring safe and continuous pump operation for more than 8000 hours.

    3. Compact structure, small size, low noise level, remarkable energy saving, easy maintenance, no pump room required, can operate submerged in water, significantly reducing project costs.

    4. The pump sealing chamber is equipped with a high-precision and interference-resistant water leakage detection sensor, and the stator winding has integrated thermal components for absolute protection of the pump motor.

    5. It can be equipped with an automatic protection control cabinet according to user needs, which absolutely protects against water leakage, electric leakage, overload, and overtemperature, improving product safety and reliability.
    6. The float ball switch can automatically control the pump start and stop according to the required liquid level, without the need for supervision, making it very convenient to use.

    7. It can be equipped with a dual-rail automatic coupling system according to user needs, greatly facilitating installation and maintenance, without the need for personnel to enter the sewage well.

    8. It can be used across the entire lift height range ensuring the motor is not overloaded.

    9. There are two different installation types: fixed automatic coupling system and free mobile installation system.

    Main uses of the WQ(QW) type submersible sludge pump

    ● Discharge of wastewater from enterprises

    ● Discharge system of urban sewage treatment plants

    ● Drainage stations for metro, basements, and civil defense systems

    ● Discharge of wastewater from hospitals, hotels, and high-rise buildings

    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 。
