Product Description

The SOW series horizontal single-stage split-casing double-suction centrifugal pump stands as a beacon of innovation and excellence in the realm of split-casing pumps. This latest generation marvel is meticulously crafted with an impeccable spectrum, a superb model, and unparalleled performance. Its structure exudes innovation and reliability, ensuring effortless maintenance and an extended service life. Our esteemed SOW pump line boasts an impressive array of 46 models and 390 fundamental specifications. With the integration of prime impellers, modified impellers, and cutting-edge designs, the spectrum is comprehensive, offering superior efficiency and an extensive performance range. This allows users to seamlessly meet their needs across various work flow points and head requirements. Through meticulous manufacturing and stringent quality control, this product has ascended to a domestic leadership position. The series dutifully adheres to ISO2548C, GB3216C, and GB/T5657 standards.

The design incorporates a double-suction impeller, masterfully crafted to minimize axial force, ensuring optimal performance. With the CAD hydraulic model, the pump's design is refined to perfection, offering superior performance. The inclusion of a prototype impeller, alongside the versatile modified impeller, allows the pump to adeptly adapt to diverse working conditions, significantly boosting efficiency.
In response to force conditions, the pump is designed with a double volute form to mitigate radial force, resulting in minimal bearing stress and enhanced longevity. The installation process is simplified, with automatic calibration of the pump cover. The relative positioning of the motor and pump's input and output pipelines can be tailored to meet specific user site requirements. The pump's inlet is swirl-free, ensuring smooth operation and minimal loss. Precision casting results in an impeccably smooth surface on the pump casing and impeller, delivering exceptional anti-cavitation performance and remarkable efficiency.

Between-the-bearings: Our split-case pumps are expertly engineered as 'between-the-bearings' pumps, where the impeller is strategically mounted on a shaft supported by robust bearings on both sides, ensuring unmatched stability and efficiency.

Double-suction impeller: The split-case pumps in our collection stand out as the quintessential choice featuring a double-suction impeller. This design innovation significantly reduces the bearing load compared to single-suction alternatives, facilitating enhanced durability and performance.

High-precision casting impeller: Crafted for excellence, our impellers boast high-precision casting to ensure optimal performance. Available in premium materials like cast iron, stainless steel, and bronze, they promise exceptional reliability and longevity.

 

Packing seals: A trusted sealing solution, packing seals have been the go-to choice for many years, utilizing rope-like materials to wrap around the pump shaft, effectively minimizing fluid loss. However, wear over time may cause increased fluid loss and impact lubrication or ease of replacement, requiring careful maintenance.

Mechanical seals: Preferred for their superior performance and durability, mechanical seals are the modern solution against leakage issues. They offer multiple sealing points, effectively reducing leak possibilities, making them ideal for demanding applications where leakage prevention is paramount.

 

Flexible couplings
Flexible couplings: Unlike their rigid counterparts, our flexible couplings excel in accommodating movement such as vibrations and thermal expansions without sustaining damage. Ideal for applications with unavoidable misalignment, they also dampen operating noise. Though their design may be more intricate and costly, the long-term maintenance savings and protection offered to shafts and bearings are considerable.

We use wear-resisting disc coupling or pin coupling for optimal performance and durability in demanding applications.
