    Product Description

    The SAP series of horizontal double-suction split casing centrifugal pumps is a single-stage, double-suction, horizontal split casing clean water centrifugal pump, designed according to national standard norms. It is an efficient and energy-saving product, featuring a simple structure and excellent performance. Its series grade, standardization, and universality are high. This pump has advanced performance, stable, safe, and reliable operation. New structures and new materials are used in its design, making it suitable for transporting various types of 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 SAP series of horizontal double-suction split casing centrifugal pumps is mainly suitable for factories, cities, mines, power plants, agricultural fields, hydraulic projects, among others. It can also use wear-resistant new structure materials and flow components (for example, the impeller can be made of cast steel and brass) to transport rivers with sediments and waters of similar quality. It has a wide flow range and is one of the most widely used centrifugal pumps.

    Introduction to the structure of the SAP series of horizontal double-suction split casing centrifugal pumps

    1. The SAP series of horizontal double-suction split casing centrifugal pumps is installed horizontally, with the inlet and outlet located below the pump shaft, perpendicular to the shaft in the horizontal direction. During maintenance, it is not necessary to dismantle the inlet and outlet pipes or the electric motor. From the transmission direction, the pump rotates clockwise (according to user needs, it can also rotate counterclockwise).

    2. The main parts of the SAP double-suction centrifugal pump include: pump body, pump cover, impeller, shaft, double-suction sealing ring, shaft sleeve, etc. Except for the shaft, which is made of high-quality carbon steel, the other main parts are made of cast iron, cast steel, or stainless steel.

    3. The body and cover of the SAP double-suction centrifugal pump form the impeller working chamber. There are threaded holes on the inlet and outlet flanges to install vacuum and pressure gauges. At the bottom of the inlet and outlet flanges, there are threaded holes for drainage.

    4. The impeller of the SAP double-suction centrifugal pump, which has passed the static balance test, is fixed to the shaft by a sleeve and nuts on both sides of the sleeve. The axial position can be adjusted by the sleeve nuts. The axial force of the impeller is balanced thanks to the symmetrical arrangement of its blades and the water inlet on both sides.

    5. The bearings of the SAP double-suction centrifugal pump are radial ball bearings. The bearings are mounted inside the bearing housing, installed at both ends of the pump body, and lubricated with grease.

    6. The double-suction sealing ring of the SAP centrifugal pump is used to reduce water leakage from the pump pressure chamber to the suction chamber.

    7. The SAP double-suction centrifugal pump is directly driven by an electric motor through an elastic coupling, and when necessary, it can also be driven by an internal combustion engine.

    8. The shaft seal of the SAP double-suction centrifugal pump is a soft packing seal (mechanical seal can also be equipped if necessary). To prevent air from entering the pump and to cool and lubricate the sealing chamber, a packing ring is installed between the packings. During pump operation, a small amount of high-pressure water flows through a trapezoidal groove on the opening surface of the pump cover into the packing chamber, acting as a water seal.

    9. Rotation direction of the SAP double-suction centrifugal pump: viewed from the motor end towards the pump, the SAP series rotates counterclockwise, with the inlet on the left and the outlet on the right; if it rotates clockwise, the inlet is on the right and the outlet on the left.

    10. Scope of supply of the SAP double-suction centrifugal pump: complete supply of split casing centrifugal pump, electric motor, base, coupling, short inlet and outlet pipes, etc.

    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 。
