    The GC type horizontal multistage boiler feed pump is a horizontal centrifugal pump, single suction, multistage and segmented. It has features such as high efficiency, wide performance range, safe and stable operation, low noise, long service life, and easy installation and maintenance. This type of pump belongs to an old model that is being phased out; the self-balancing DG and DGP type boiler feed pump series are products that meet national standards and replace the old GC series. This series of boiler feed pumps is suitable for transporting clean water or liquids with physicochemical properties at temperatures below 110°C.

    Product Description

    The GC type multistage boiler pump is a horizontal centrifugal pump, single suction and segmented multistage, commonly used for hot water replenishment and hot water circulation, featuring high efficiency, wide performance range, safe and stable operation, low noise, long service life, and easy installation and maintenance. It is used to transport clean water below 110°C or media with physical and chemical properties similar to clean water, widely applied in industrial and urban water supply and drainage, high-rise building pressurization, garden irrigation, fire protection pressurization, long-distance water transportation, heating, baths, and other cold and hot water circulation and pressurization systems, as well as auxiliary equipment, especially suitable for small boiler feed. Due to its simple structure and stable performance, the GC pump was one of the most used in the early stages of water pump development. With technological advances and improved manufacturing precision, this pump no longer meets many users' needs in terms of energy saving, flow, head, and efficiency, becoming an obsolete model. Currently, the most used boiler feed pumps are DG type pumps and DGP type self-balancing boiler feed pumps, both manufactured according to national standards with efficient and energy-saving hydraulic models, wide flow and head adjustment ranges, and significant energy-saving effects, basically replacing the GC thermal cycle/multistage boiler pumps.

    Performance Curve of GC Type Boiler Feed Pump

     

    Although the GC thermal cycle/multistage boiler pump is gradually being phased out by users, this pump has mature technology, simple maintenance, and still offers good cost performance under simple working conditions with low flow and head, such as in small boilers, garden irrigation, and fire protection pressurization. Our company is a veteran manufacturer of multistage pumps, independently established after the restructuring of Zhonglian Pump Industry, with more than 30 years of experience in research, development, and manufacturing of multistage pumps. With strong technical capability, extensive production experience, comprehensive inspection methods, a professional design and research team, and technical production personnel, it has become a key national high-tech enterprise in multistage pump equipment. Main products include: self-balancing multistage pumps, multistage boiler feed pumps, vertical multistage water pumps, mining multistage pumps, corrosion-resistant multistage pumps, among others. All produced multistage centrifugal pumps use computer-aided design and optimization, ensuring stable and reliable quality.

    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 。
