This latest-generation pump is celebrated for its comprehensive spectrum, exceptional design, and superior performance. With an innovative and trustworthy structure, it promises ease of maintenance and longevity. Our SOW pump range comprises an impressive 46 models and 390 essential specifications, featuring prime and modified impellers as well as cutting-edge designs. This broad spectrum ensures high efficiency and exceptional performance across a wide range of applications, tailored precisely to meet user demands at any operational point. Meticulously crafted with stringent quality control, this product stands at the forefront of domestic industry standards, adhering to ISO2548C, GB3216C, and GB/T5657 guidelines.
Equipped with a double-suction impeller, our pump minimizes axial force, ensuring optimal operational efficiency. The CAD hydraulic model employed in its design guarantees peak performance, while the adaptable nature of the prototype impeller, paired with its modification capabilities, allows it to meet diverse operational requirements and enhance performance.
Designed with double volute form based on force analysis, our pump significantly reduces radial forces, resulting in minimal bearing strain and extended longevity. Installation is a breeze, with automatic pump cover calibration. The relative positioning of the motor and pump in relation to the pipeline can be customized to suit specific user site requirements. The pump inlet is engineered to prevent swirl, ensuring smooth operation with minimal loss. Precision casting delivers ultra-smooth surfaces on the pump casing and impeller, enhancing anti-cavitation properties and boosting efficiency.

Between-the-bearings: Discover the engineering marvel that is the split-case pump! Designed as a "between-the-bearings" pump, this innovative creation rests the impeller on a robust shaft, fortified by bearings strategically positioned on both sides. This ensures remarkable stability and efficient operation.
Double-suction impeller: Experience the unparalleled efficiency of split-case pumps, which stand out as the only COMMON type equipped with a double-suction impeller. This exceptional feature dramatically reduces the load on bearings, offering a superior advantage over single-suction impellers that only draw water from one side.
Our high-precision casting impeller guarantees optimum performance, crafted meticulously with materials such as cast iron, stainless steel, and bronze for unmatched durability and reliability.
Packing seals have long been revered as the quintessential sealing solution, utilizing rope-like materials to envelop the pump shaft, filling voids, and minimizing fluid loss. However, as the gland packing material gradually wears, increased fluid loss, impaired lubrication, and hindered ease-of-replacement may occur, impacting performance.
In modern applications where leakage is a critical concern, mechanical seals have emerged as the preferred choice over traditional packing seals. These advanced seals boast enhanced durability, crafted to endure rigorous conditions, and employ multiple sealing points to nearly eradicate leakage issues.
Flexible couplings
Unlike rigid counterparts, flexible couplings are designed to handle movements such as vibrations and thermal expansion without incurring damage. Perfect for scenarios with unavoidable misalignment between drive and pump shafts, they excel in reducing excessive noise and offer long-term maintenance savings despite a more complex and costly design.
For ultimate durability and performance, we incorporate wear-resisting disc couplings or pin couplings, ensuring our systems remain resilient against wear and tear.
