    Product Description

    Advantages of the explosion-proof BQS type submersible drainage and sand pump for mining

    1. The explosion-proof BQS type submersible drainage and sand pump for mining has excellent performance, can maintain stability without clogging during operation, and has strong drainage and sand removal capacity. The electric pump design uses an independent series mechanical seal and innovative double-face mechanical seal technology.

    2. Regarding structural optimization, special consideration has been given to the mechanical seal's tightness and overall operational reliability. Through optimized design, it is lighter and more practical, as well as consuming less energy. Additionally, the pump can operate dry for a long time.

    3. Regarding the motor, an IPX88 protection grade is used, especially suitable for the underground environment of coal mines. The submersible motor has excellent cooling effect and low temperature rise, further improving durability and long-term stability. The class F insulation design also extends the motor's service life.

    4. The overall pump structure is a vertical submersible design, with electromechanical integration, using bottom suction, suitable for shallow water level environments. The product consists of two main parts: flow components and motor. According to the flow discharge form, it can be divided into external type, internal type, and semi-internal type.

    5. The pump body and impeller have been carefully selected and combined to ensure clog-free performance and high efficiency, with a flat power curve that avoids overloads. The motor uses a specially designed submersible motor, with IPx8 protection and class F insulation, ensuring safe and reliable operation under various conditions.

    6. Regarding the mechanical seal, the motor shaft is sealed with an independent series double mechanical seal, effectively preventing media from entering the motor interior, improving the seal's reliability and service life.

    7. The oil chamber design acts as a barrier for the media inside the motor, further preventing media penetration into the pump shaft and protecting the motor's operational stability. The bearing part consists of double-row angular contact bearings and deep groove bearings, ensuring the pump's stability and service life during operation.

    8. The cable uses a flame-retardant cable for coal mines according to standard MT818.5-2009, designed to meet long-term stable operation requirements, ensuring safe use in various environments.

    9. The overall design considers the specificity of the usage environment. The product is suitable for places with poor water quality, containing impurities, coal sludge, and much sand, making it an ideal choice for various underground situations in coal mines.

    Product Parameters

            The explosion-proof type BQS submersible pump for wastewater and sand discharge for mining is designed and manufactured according to the explosion-proof standard MT/T671-2005 "Explosion-proof electric submersible pump for coal mines." This pump uses an efficient and energy-saving "bottom suction" design, specially designed for underground coal mine environments with large amounts of coal slurry, water, and sand, hence it is also called a submersible sand discharge pump. The pump has optimized the product structure and parameters according to usage conditions, overcoming technical difficulties in manufacturing processes, operational efficiency, and leak-proof sealing.

    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 。
