This state-of-the-art innovation represents the newest generation of split-casing double-suction pumps, exhibiting an impressive array of features including an impeccable spectrum, advanced model design, and superior performance. Crafted with an innovative and robust structure, it ensures effortless maintenance and a remarkable lifespan. Presenting a comprehensive range of 46 models and 390 basic specifications, our SOW pump stands as a testament to versatility and high performance. By incorporating both prime and modified impeller options, along with adaptable cutting types, it delivers an extensive efficiency and performance range within its spectrum, precisely accommodating user demands across varying workflow and head requirements. Meticulously manufactured under stringent quality control, this product achieves a leading position in domestic markets. The pump series adheres to esteemed standards such as ISO2548C, GB3216C, and GB/T5657, assuring quality and reliability.

Engineered for excellence, this pump features a double-suction impeller that significantly minimizes axial force. The integration of a CAD-engineered hydraulic model ensures optimal design and exceptional performance. Enhancing its adaptability, the pump can utilize both a prototype and modified impeller to suit diverse working conditions, thereby maximizing efficiency.
Designed with precision, the pump incorporates a double volute form to effectively reduce radial force, resulting in minimized bearing force and extended lifespan. Its installation process is remarkably straightforward, featuring automatic calibration of the pump cover. The relative positioning of the motor, pump inlet, and outlet pipelines can be customized to align with user-specific site requirements. Offering swirl-free inlet, smooth operation, and minimal loss, the pump excels in performance. With precision casting, the surfaces of the pump casing and impeller are exquisitely smooth, providing exceptional anti-cavitation capabilities and superior efficiency.

Between-the-bearings: Our state-of-the-art split-case pumps feature an innovative 'between-the-bearings' design. This revolutionary setup mounts the impeller on a shaft, expertly supported by bearings on both sides, ensuring exceptional stability and performance.

Double-suction impeller: Uniquely, split-case pumps are the only widely-used pumps with an efficient double-suction impeller. This superior design imposes significantly fewer loads on the bearings compared to single-suction impellers, delivering reliable and smooth operation.

Our high-precision casting impeller guarantees remarkable performance. Crafted from premium materials such as cast iron, stainless steel, and bronze, it exemplifies quality and durability.

 

Packing seals have been the industry staple for sealing solutions over the years. These seals employ rope-like materials to wrap around the pump shaft, effectively reducing fluid loss by filling dead spaces. However, as time progresses, wear may increase fluid loss and compromise lubrication, necessitating regular maintenance to retain optimal functionality.

Mechanical seals offer a modern, superior alternative to traditional packing seals, especially in applications where leakage prevention is crucial. These advanced seals boast enhanced durability and are designed to withstand substantial wear, utilizing multiple sealing points to virtually eradicate leakage issues.

 

Flexible couplings
In contrast to rigid couplings, flexible couplings adeptly handle slight movements such as vibrations and thermal expansion, thus avoiding any damage. This adaptability makes them perfect for scenarios with inherent misalignment between drive and pump shafts. Their ability to absorb vibrations also helps reduce operational noise. Although the design is more intricate and costly, the long-term maintenance savings, achieved through protection against shaft and bearing damage, make flexible couplings a wise investment.

For optimal performance, we implement wear-resisting disc couplings or pin couplings, ensuring durability and efficiency.
