    Product description

     

    　　The GS high-efficiency and energy-saving double-suction open design centrifugal pump is a single-stage, double-suction, horizontally open clean water centrifugal pump. It is a high-efficiency and energy-saving product successfully developed by our company in collaboration with the University of Science and Technology, based on the original series of double-suction pumps S, SH, SA, after thorough research and design to improve its performance. It has a simple structure and excellent performance. Its series grade, standardization, and universality are high. This pump has advanced performance, stable operation, safe and reliable. New structures and materials are used in its design, making it suitable for transporting various media. It is intended for transporting clean water without solid particles or liquids with physical and chemical properties similar to water, with a transported medium temperature from 0℃ to 80℃ and an allowable inlet pressure of 0.6MPa.

    The GS high-efficiency and energy-saving double-suction open design centrifugal pump is mainly suitable for factories, cities, mines, power plants, agricultural fields, hydraulic projects, among others. It can also use new wear-resistant structural materials and flow passage components (for example, the impeller can be made of cast steel and brass) to transport river sediments and waters of similar quality. It has a wide flow range and is one of the most versatile centrifugal pumps.

     

           Image 1 Technical advantages of the GS high-efficiency and energy-saving double-suction open design centrifugal pump 
     

    　　Advantage one: high efficiency

    　　The GS high-efficiency and energy-saving double-suction open design centrifugal pump uses a stepped arrangement structure of the two halves of the impeller blades, which changes the blade frequency (frequency of the blades passing through the pump body tongue), reducing the liquid flow pulse (approximately a reduction of 0.1% to 0.4% in head). This makes the liquid flow more stable, with higher efficiency, less vibration, and more stable and reliable operation.

    　　Advantage two: low pulsation

    　　The GS high-efficiency and energy-saving double-suction open design centrifugal pump introduces excellent domestic and international hydraulic models, uses CFD (computational fluid dynamics) analysis methods for specific optimization and improvement; its performance indicators far exceed the industry level, reaching an advanced international level with a very high efficiency exceeding 92%.

    　　Advantage three: low cavitation margin

    　　The inlet edge shape of the blades of the GS high-efficiency double-suction centrifugal pump is optimized with a convex arc design, increasing the flow passage area at the inlet, reducing the inlet velocity, and increasing the pressure at the inlet edge, which improves the cavitation margin.

    　　The blade head adopts an aerodynamic wing-type design, which reduces flow impact loss and vortices, not only increasing the maximum efficiency but also expanding the high-efficiency zone, with uniform pressure distribution and better cavitation resistance performance.

    　　Advantage four: improved reliability

    　　The high-head and high-efficiency open design pump uses a double volute design, the pump body and cover are reinforced with ribs, and the structure is optimized using ANSYS mechanical analysis software. The pump casing has high strength, and each GS high-efficiency double-suction open design centrifugal pump undergoes strict hydraulic testing according to the GB/T5656 standard "Technical conditions for centrifugal pumps" to ensure quality and performance.

    　　Advantage five: high adaptability

    　　The high-efficiency double-suction open design centrifugal pump has a wide high-efficiency zone that can meet a greater variety of user requirements; additionally, we adopt a two-wheel impeller configuration so that the pump has excellent selectivity, greatly ensuring that the user's operating point can be within the high-efficiency range.

    　　The pump's inlet and outlet flanges can be processed according to GB, ISO, DIN, BS, ANSI standards, among others.

    　　Pump casing channel: ultra-slippery energy-saving coatings, wear-resistant and corrosion-resistant coatings, among others, can be selected.

    　　For transporting high-temperature media, the GS-R type structure can be used, with a central support and water-cooled bearing housing.

    　　Shaft sealing system: can perform packing sealing, single-face interchangeable sealing, and can also be configured according to user requirements with mechanical seals in sets, double-face mechanical seals, and standard AP682 flushing system.

    　　Bearing lubrication system: can use grease lubrication or light oil lubrication for flexible selection.

    　　Bearing cooling system: depending on the medium temperature, natural cooling or water cooling can be chosen for the bearing housing.

    　　Remote monitoring: the bearing housing is equipped with interfaces for temperature and vibration measurement, facilitating remote monitoring.

    　　Advantage six: high parts universality

    　　Except for some parts such as the pump body, cover, and impeller, the rest use modular design, achieving parts standardization. The coaxial system bearing components, sealing parts, sleeves, and retaining rings are interchangeable, facilitating mass production of the pump.

    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 。
