    Flow: 15-220m3/h

    Manometric height: 5-65m

    Power: 2.2-7.5kw

    Pipe diameter: 40-200mm

    Rotation speed: 2860r/min

    Price: 0.18-4.19 ten thousand

     

    QS type submersible water filling pump (hereinafter electric pump), the electric pump consists of two main parts: the water pump and the motor. The water pump is located at the top of the electric pump and has a centrifugal structure. The motor is located at the bottom of the electric pump and is a three-phase asynchronous water filling motor. The stator winding and the core of the water filling motor are directly submerged in water, providing good cooling effect and no pollution, thus overcoming the disadvantages of other electric pumps which, during operation, allow the "O" ring seal and mechanical seals to leak water into the motor chamber, significantly improving the electric pump.

    Product description

    The QS type submersible pump for water filling wells (hereinafter, the electric pump) consists of two main parts: the water pump and the motor. The water pump is located at the top of the electric pump and has a centrifugal structure. The motor is located at the bottom of the electric pump and is a three-phase asynchronous motor of the water filling type. The stator winding and the core of the water filling type motor are directly submerged in water, providing good cooling effect and generating no pollution, thus overcoming the disadvantages of other electric pumps which, during operation, allow water to leak into the motor compartment through the "O" ring seal and mechanical seals, significantly improving the efficiency of the electric pump's use. 
    Submersible pump for water filling type well
     
    The QS type submersible pump for wells is widely used in irrigation and drainage of agricultural fields, sprinkler irrigation, groundwater extraction, water supply for domestic use, supply and drainage systems in industrial and civil buildings, as well as in water conveyance in mountainous areas and drainage in low-lying areas. 

    Product parameters

    Meaning of the model and working conditions of the QS type submersible well pump with water filling

    QS type submersible pump with water filling

    For example: QS20-40/2-4

    QS type submersible pump with water filling

    20-Flow rate (m3/h)

    40-Head (m)

    2-Number of stages

    4-Power (kw)

    Working conditions:

    1. Power supply: frequency 50Hz, voltage 380 volts (tolerance 5%-10%) three-phase alternating current.

    2. Water source: generally clean non-corrosive water, sand content not exceeding 0.02%, pH value: 6.5-8.5. The temperature of the extracted water should not exceed 40.

    3. Installation: the electric pump must be fully submerged in water during operation, with an immersion depth not less than 0.5 meters and not more than 5 meters.

     

    Scope of application and characteristics of the QS type submersible well pump with water filling

    The QS type submersible pump must be able to operate continuously under the following usage conditions:

    1. Before using the QS type submersible pump with water filling, loosen the drain screw, add clean water (tap water or clean lake or river water) through the filling port to rinse the rust inside the motor and prolong the pump's service life. When clean water comes out of the drain hole, tighten the drain screw and gently shake to expel air from the winding, ensuring the inside of the motor is filled with clean water, then tighten the filling screw and check that the insulation resistance is not less than 5 megaohms.

    2. When the QS type submersible well pump is not in use, the water inside the motor must be drained and stored in a dry and ventilated place; the next time it is used, follow the above method. (Locking screw FP).

    3. The working medium is clean non-corrosive water, with a sand content by volume not exceeding 0.10%, pH 6-8.5, and water temperature not exceeding +40 ℃.

    4. This pump uses a sliding bearing structure and must be used in a vertical position without inclination.

    5. The immersion depth of the submersible pump with water filling must not exceed 5 m.

    Product features:

    1. The QS type submersible well pump consists of the motor and pump assembled into a single unit, with a simple structure, easy installation and disassembly, occupies little space, easy maintenance, and safe and reliable operation.

    2. The QS type submersible well pump has good cooling effect, does not cause pollution, and improves pump efficiency.

    3. Due to its special structure, the QS type submersible pump with water filling does not pollute the water source during use.

    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 。
