ODM/OEM

  • 01Research and innovation ability

    Our company has strong design and development capabilities, and can customize and technically upgrade various slurry pump products.
    At present, we have four ceramic pump research centers dedicated to making up the technical gaps in high-wear-resistance pump products. Our company follows the international advanced design theory, adopts new special ceramic materials, standardizes the production process, improves the manufacturing accuracy, further enhances the reliability of the products, and has created new products and new technologies with independent intellectual property rights. Our pump products have a number of technical patents, which are reliable, durable, efficient and energy-saving, and have created significant benefits for enterprises and society. Now our company has four series of nearly 100 models of industrial pump products, which are widely used in factories, mines, power stations, metallurgy, chemical industry and urban and rural water supply and drainage and fire extinguishing systems, and are favored by users at home and abroad.

  • 02Independent casting ability

    The strong independent casting ability guarantees the dimensional accuracy and quality of castings, and can also meet the needs of customers for mass customization and personized production.
    Our company cooperated with Sinosteel Luoyang Institute of Refractories Research Co., Ltd to establish a joint venture company, and has mastered the process technology of new ceramic material, and applied and promoted it in industrial pump products. New ceramic material has obvious advantages in terms of wear resistance, corrosion resistance, and high temperature resistance. It has also made major breakthroughs in extending service life of wet parts. Since the foundry workshop was put into production, our company has also become a research and development and production output base for new ceramic material. In the future, we will continue to absorb advanced ceramic technology at home and abroad to create a high-end platform for the development and application of industrial new materials, and contribute to the new material industry.

  • 03Production and processing ability

    There is advanced production equipment in the whole-process machining center, which have high measurement accuracy and can make product more stable and more durable.
    Shandong Zhanggu attaches great importance to the production of slurry pumps and their accessories, and has established a world-class processing center, assembly workshop and testing center. Processing equipment mainly includes: drilling machines, punching machines, CNC machining centers, five-axis machining centers, dynamic balance detectors, three-coordinate measuring instruments, etc. After a series of manufacturing processes such as casting, heat treatment, lathing, reheat treatment, painting and oiling treatment, assembly, and trial run, our pump products have a service life longer than similar products in the industry.

Sintering Process of Special Ceramic Material

Sintering (Firing) of ceramic materials is the method involving consolidation of ceramic powder particles by heating the “green” compact part to a high temperature below the melting point, when the material of the separate particles difuse to the neghbouring powder particles.

PRODUCTION PROCESS

FAQ

  • Q1What is cavitation?

    The increase velocity of the water entering a pump will cause a reduction in pressure within a unit. If this pressure falls too low, some of the water will vaporize, forming bubbles entrained in the liquid. These bubbles collapse violently as they move to areas of higher pressure creating the noise and vibration from the pump.

  • Q2How do you know if the pump is cavitating?

    The pump is cavitating if knocking noises and vibrations (like pumping gravel) can be heard when it is operating. Other signs may be erratic power consumption and fluctuations or reductions in pump output.

  • Q3If I put a bigger motor on my pump, will it pump more?

    No. The amount of water and the pressure (head) that a centrifugal pump produces is related to the rotational speed, impeller diameter and size of the impeller vanes.

  • Q4What is a centrifugal pumps minimum flow rate?

    There is no standard which establishes precise limits for minimum flow in pumps. Most centrifugal pumps should not be used at a flow rate less than 50% of the best efficiency point. If the system requires a flow rate of 50% or less then use a recirculation line to increase the flow through the pump keeping the flow low in the system. If a pump operates at at very low flows, it could overheat badly and cause noise, vibration, cavitation and mechanical damage.

  • Q5What happens if you do not have enough submergence?

    The end of the suction pipe is not submerged deeply enough, a vortex will form at the surface and cause air to be entrained in the pump reducing the pump capacity.

  • Q6What is the Best Efficiency Point (BEP)?

    The best efficiency point B.E.P. this is the point at which the pump is the most efficient and operates with the least vibration and noise. This is often the point for which pumps are rated and which is indicated on the nameplate. The pump will consume the power corresponding to its B.E.P. rating at this point.
