    Self-balancing multi-stage centrifugal pump ten advantages

    1. New structure
    The rotor parts with the symmetrical arrangement of the impeller make the axial thrust generated by the positive and reverse impeller in operation basically cancel each other, so that the balance plate device with small clearance, high pressure drop, easy erosion, easy wear and easy failure is not required to maintain the balance of the axial force, breaking through the traditional structure of the multistage pump.

    2. New technology
    Unique throttling, reducing device, odd-level balancing device, can also play the role of auxiliary support.

    3, high efficiency and energy saving
    Adopt advanced hydraulic model, self-developed energy-saving products; Because the pump rotor does not have the wear and axial pulsation of the balance disc, the neutrality of the impeller and guide vane is always in the best state, and the efficiency of the multistage pump structure will not decrease significantly with the wear of the balance disc and the forward movement of the rotor components. And there is no leakage of balanced water, reducing the volume loss, improving the operating efficiency of the pump as a whole, reducing the shaft power, and the efficiency is 2% to 3% higher than that of the ordinary multistage pump.

    4. High reliability
    Self-balanced axial force loads minimize pump wear and system interference. A very small part of the residual axial force is borne by the thrust bearing, so that the pump shaft is always in the tension state, the force state of the shaft is uniform, and the stress peak value is greatly reduced compared with the prototype structure, thus improving the rigidity and critical speed of the pump rotor, and significantly improving the smoothness and reliability of the pump rotor operation.

    5. High stability
    Through the best matching of symmetrical impeller and guide vane, as well as reasonable matching gap and wide axial throttle design, the pump can still maintain its high stability and operating efficiency after long-term operation.

    6. Good cavitation performance
    Optimized hydraulic model and structural design, special double suction structure of the first stage impeller, coupled with precision casting, reliable wear-resistant material, so that the pump has good anti-cavitation performance, the whole machine runs smoothly, low noise, the user does not need to configure additional pump or increase the height of the water tank.

    7, the machine seal strong reliability
    When the pump starts and stops, the rotor parts do not move axially, and there is no axial pulsation when working, which overcomes the problem of poor seal reliability that has been plaguing multistage pumps.

    8, easy maintenance
    The fast assembly and disassembly design allows the pump to replace seals and bearings without disassembling the pump body and inlet and outlet lines. There are no vulnerable parts such as balance plates in the pump, saving overhaul and inspection time.

    9. Low maintenance rate
    The use of silica sol precision casting process reduces the number of vulnerable parts and maintenance disassembly, extends the product life, and avoids a series of problems caused by too much disassembly to the maximum extent, and reduces the maintenance cost.

    10, strong applicability
    Advanced modular design, after a large number of use, long-term testing of local components, parts have a high degree of interchangeability. The small gap balancing disc device is eliminated, and the multi-stage pump with traditional structure is suitable for the occasions where the medium is more severe.

    Our company is the production of all kinds of pumps and pump boat professional manufacturers, with its unique professional technology to occupy the market, to provide users with satisfactory and qualified products, the implementation of lifelong service is my company's service purpose. We will take the principle of capital preservation and small profit, according to IS09001 international quality management system to provide you with good service. To this end, our company hereby makes the following commitments:


    1. Our company organizes production and testing according to national standards, industry standards and technical conditions stipulated in the contract, and runs strictly according to ISO9001 quality assurance system to ensure that unqualified products do not leave the factory.


    2, our company to provide users with free technical advice, according to user requirements to provide design solutions, and actively cooperate with the owner and supervision. After the equipment is put into operation, professional and technical personnel will be sent to assist in the management of on-site production.


    3, During the installation period, if necessary, the company can send professional and technical personnel to supervise and cooperate with the site to ensure the installation progress and quality. Our company is free to train operators for users, to the independent skilled operation, free to provide users with relevant operating procedures and rules and regulations.


    4, according to the design standards and design parameters of the equipment and operation indicators for acceptance assessment, and responsible for product performance monitoring, fail to meet the standards by our company is responsible for rectification until the standard.


    5, our company for the equipment warranty period: from the equipment installation and acceptance into operation and the owner issued a preliminary acceptance certificate from the date of operation 12 months, and lifelong maintenance. After the equipment is delivered through operation, during the warranty period, the quality problem of our equipment fails. After receiving your written notice, we will reply within half an hour, and we will send someone to the scene for maintenance and other after-sales services within 24 hours to ensure the normal operation of the unit. The warranty expires, our company only charges a certain cost for equipment maintenance and repair.


    6, the company's products are all implemented "three guarantees", the product in the "three guarantees" period is indeed a quality problem, strict performance of the contract stipulated in the liability. And at the time of delivery to provide this batch of products certificate, product specifications.


    7, our company according to the actual situation, guarantee to provide maintenance parts and according to user requirements, do a good job of maintenance services, to provide users with special tools and spare parts, this batch of products also implement the "three guarantees".


    8, our company regularly or irregularly telephone return visits (or on-site inspection), listen to user opinions, exchange relevant experience, and remote network guidance, the after-sales service to do better and more perfect.


    The DGP pump series is a horizontal self balancing centrifugal pump with a suction structure, which can be divided into single suction multi-stage structure and double suction multi-stage structure according to the suction form. The inlet and outlet of the pump are both vertically upward, and the inlet, middle, outlet, and secondary inlet sections of the pump are connected into one body by tightening bolts. The required pump head can be determined by increasing or decreasing the number of pump stages.


    The main components of a water pump include the inlet section, middle section, outlet section, secondary inlet section, positive guide vanes, and reverse guide vanesBlades, positive impellers, reverse impellers, shafts, throttling and pressure reducing devices, gear sleeves, bearing bodies, transition pipes, etc.
