Product Description

Product Description

Introducing the SOW series: the epitome of modern engineering in the realm of horizontal single-stage split-casing double-suction centrifugal pumps. Meticulously designed to embody the latest generation of split-casing technology, this pump boasts an unparalleled combination of an extensive model range, innovative design, and remarkable performance. Its architecture is not only reliable but also crafted for simplicity in maintenance, ensuring an extended lifespan. Currently, our SOW series features 46 sophisticated models and encompasses 390 foundational specifications. Utilizing advanced impeller designs, both prime and modified, alongside cutting-edge adaptations, it offers a comprehensive performance spectrum, guaranteeing high efficiency and meeting the diverse demands of users across various operations. With impeccable manufacturing techniques and stringent quality control measures, this product has achieved a pioneering position in the domestic market. It rigorously adheres to international benchmarks, namely ISO2548C, GB3216C, GB/T5657 standards, assuring its superior quality and performance.

Engineered with precision, the double-suction impeller significantly minimizes axial force, enhancing the longevity and efficiency of operation. The use of CAD hydraulic modeling ensures optimal design, delivering outstanding performance. Furthermore, the inclusion of both prototype and modified impellers allows for adaptability across diverse working conditions, further boosting efficiency and operational effectiveness.
Designed for durability and efficiency, the pump features a double volute form to effectively reduce radial force, thereby minimizing bearing stress and extending the life of the pump. Its ease of installation and automatic calibration of the pump cover make it user-friendly, while its adaptable design allows for modifications to the relative positions of the pipeline, motor, and pump in accordance with user requirements. The pump's inlet is engineered to minimize turbulence, ensuring smooth operation and reduced energy loss. Precision casting results in a sleek pump casing and impeller surface, delivering superior anti-cavitation properties and heightened efficiency.

Between-the-Bearings Excellence: Our split-case pumps are ingeniously designed as "between-the-bearings" models. This sophisticated arrangement features the impeller mounted on a robust shaft, supported by resilient bearings on both sides, ensuring optimal stability and performance.

Revolutionary Double-Suction Impeller: Uniquely distinguished as the only common pump type sporting a double-suction impeller, our split-case pumps impose significantly less strain on bearings compared to single-suction alternatives, effectively enhancing longevity and reliability.

High-Precision Casting Brilliance: Our meticulously crafted impeller, available in cast iron, stainless steel, and bronze, guarantees superior performance, providing unwavering durability and unmatched precision in every operation.

 

Enduring Packing Seals: Renowned for their extensive use, packing seals ingeniously utilize rope-like materials that encircle the pump shaft, effectively filling voids and curbing fluid loss. However, as they age, increased leakage may occur, potentially hindering lubrication and ease of replacement.

Advanced Mechanical Seals: Favored for their superior durability and efficiency, mechanical seals are the premier choice for applications demanding minimal leakage. These advanced seals employ multiple sealing points, virtually eradicating leakage and providing enhanced resilience over traditional options.

 

Versatile Flexible Couplings
Dynamic Flexible Couplings: Unlike their rigid counterparts, flexible couplings adeptly accommodate movement, including vibrations and thermal expansion, without sustaining damage. Ideal for situations with unavoidable shaft misalignment, they effectively absorb vibrations, reducing operating noise. Though their design is complex and more costly, the long-term savings in maintenance due to their protective nature far outweigh the initial investment.

Our Selection: Employing wear-resistant disc or pin couplings ensures enhanced durability and sustained performance.
