    Product Description

           The plunger pump, as a typical representative of reciprocating pumps, performs a reciprocating linear movement of the plunger to create a periodic volume change in the pump chamber, achieving suction and discharge of the fluid. When the plunger moves backward, the volume of the pump chamber expands forming a negative pressure, the suction valve opens to draw in the fluid; when the plunger moves forward, the chamber compresses generating high pressure, the discharge valve opens to push the fluid. Our company produces the 3P series of high-pressure plunger pumps in two forms: fixed and mobile, with more than one hundred models and specifications, precisely adapting to different usage conditions. They can be used in hydraulic presses, valve pressure testing, oil pressure, high-pressure cleaning, coal mining, oil drilling, water jet cutting, oil fracturing, water injection in oil fields, among others, and are widely applied in the chemical, fertilizer, light industry, food, salt mine water injection, emulsions, and other industrial fields.

           Image 1 Main features of the 3P series horizontal high-pressure plunger pump

              1. Driving part (see figure 2-1)

    The driving end is entirely a closed-box casting structure, with good rigidity, simple mechanism, and symmetrical design. According to the lubrication method, it is divided into splash lubrication and pressure lubrication; the driving part is driven by an electric motor or diesel engine through a pulley or gearbox to operate the high-pressure reciprocating pump. The rubber triangular belt uses a new narrow V-belt, the crankcase has an oil reservoir at the bottom to store lubricant, which lubricates by splash during the reciprocating movement of the crankshaft and connecting rod. The crankshaft ends use roller bearings, the big end of the connecting rod has thin-walled bearings, the small end uses tin bronze bushings, the cross pin and cross hole have dynamic fit, and the intermediate rod is sealed with a rubber ring with a frame structure to prevent lubricant leakage at the driving end. The plunger surface is treated with a special spraying process, the sealing packing uses packings made of new carbon fibers, adjusted by a pressure nut.

     

     

             2. Hydraulic part (see figure 2-2)

    The pump body material is selected according to the user's need to transport various high-pressure liquids, using forged carbon alloy steel, stainless steel, etc. The inlet and outlet valves use flat, conical, or ball valves, made of high-quality stainless steel. The main components such as valve seat, valve core, valve sleeve, and seal body are all made of stainless steel.

            

              3. The structure of the hydraulic end varies according to the transported medium, flow, and pressure, with the following forms:

    A. For pumps with pressure below 25 MPa and small flow. Features: the inlet and outlet valves are identical and interchangeable, simple mechanism, few sealing surfaces, it is the most common hydraulic end structure.

    B. For pumps with pressure below 25 MPa and small flow. Features: when disassembling the inlet valve, it is not necessary to disassemble the outlet valve, but the pump head weight increases, and the flanges and sealing surfaces are more than in structure A.

    C. For pumps with pressure below 25 MPa and medium flow. Features: the inlet and outlet manifold is separated from the pump head, which reduces the head weight but increases the sealing surfaces.

    D. For pumps with pressure below 25 MPa and large flow. Features: the inlet and outlet valves are very easy to assemble and disassemble, the pump head is modular type.

    E. For pumps with pressure above 25 MPa. Features: uses combined valves to effectively prevent cracking of the pump head.

            1. High pressure and high efficiency: optimization of the plunger structure and flow path design to achieve high pressure (such as 6 MPa) and large flow (25 L/min), suitable for high-pressure scenarios such as oil and gas extraction and chemical industry.

    2. Noise resistance and accurate diagnosis: uses Gammatone sound spectrum technology to extract fault signals in strong noise, with a fault diagnosis accuracy of over 90% with small samples, reducing the risk of false positives.

    3. Long-life sealing: the polytetrafluoroethylene composite sealing ring is corrosion-resistant and low friction, with a service life of more than 1000 hours, suitable for acidic, alkaline, and organic solvent environments.

    4. Intelligent adaptation to complex conditions: integrates sensors to monitor pressure and temperature in real time, supports adaptive adjustment and remote maintenance, improving energy efficiency.

    5. Energy saving and environmental protection: optimizes the collection and transportation process to reduce surface construction costs by 20%, combining technologies such as ethane recovery to reduce resource waste.

    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 。
