As the latest evolution in the realm of split-casing double-suction pumps, it proudly boasts a perfect spectrum, exceptional models, and unmatched performance. Its innovative and reliable structure promises not only ease of maintenance but also a commendably long lifespan. The SOW pump line includes an impressive array of 46 models and 390 foundational specifications. By employing both prime and modified impellers, alongside cutting-edge technology, it delivers a broad-based spectrum characterized by high efficiency and a versatile performance range. This ensures that it adeptly meets any user need across various work flows and head parameters. Meticulously crafted and subjected to stringent quality controls, this product stands as a leader in the domestic market, meeting and surpassing ISO2548C, GB3216C, and GB/T5657 standards.

Experience the engineering marvel of our double-suction impeller, meticulously designed to minimize axial force, ensuring smooth and efficient operation. The CAD hydraulic model refines this design to perfection, offering exceptional performance. With the addition of a prototype impeller, users have the flexibility to switch to a modified impeller to suit diverse working conditions, thereby elevating efficiency and adaptability.
Engineered for excellence, this pump incorporates a double volute form that expertly manages radial force, minimizing bearing stress and extending the pump's lifespan. Installation is a breeze, with features like automatic calibration of the pump cover and the adaptable positioning of the motor and pump inlets and outlets to suit specific site requirements. The pump boasts a swirl-free inlet, guaranteeing smooth operation and minimal loss. Precision casting ensures that both the pump casing and impeller surfaces are exquisitely smooth, enhancing significant anti-cavitation performance and maximizing efficiency.

Detailed Photos

Between-the-bearings: Our exceptional split-case pumps, also known as 'between-the-bearings' pumps, ingeniously mount the impeller on a shaft that is masterfully supported by bearings on both sides. This innovative design ensures seamless and efficient operation.

Double-suction impeller: Experience the unparalleled performance of split-case pumps, the only widespread pump type boasting a double-suction impeller. This advanced feature significantly reduces the load on bearings, unlike single-suction impellers that draw water from only one side, ensuring robust and reliable functionality.

Our high-precision casting impeller guarantees outstanding performance. Available in premium materials such as cast iron, stainless steel, and bronze, it ensures durability and reliability for all your needs.

Packing seals have been the cornerstone of sealing solutions for many years. These rope-like materials adeptly wrap around the pump shaft, effectively filling dead spaces and minimizing fluid loss. However, as the gland packing material wears over time, fluid loss may increase, potentially affecting lubrication and ease of replacement.

Mechanical seals are the top choice over traditional packing seals in applications where leakage must be strictly avoided. These advanced seals are remarkably more durable, crafted to withstand serious challenges. With multiple sealing points, they virtually eradicate leakage issues, offering peace of mind and superior performance.

Versatile Couplings
In stark contrast to rigid couplings, flexible couplings elegantly handle movement such as vibrations and thermal expansion without sustaining damage. Perfect for applications with unavoidable misalignment between drive and pump shafts, they also excel in reducing excessive operating noise. While they entail a more intricate and costly design, their ability to protect shafts and bearings results in substantial maintenance savings over time.

Our commitment to durability is evident with our use of wear-resistant disc or pin couplings, ensuring longevity and reliable performance in demanding conditions.

Product Application

This exceptional product showcases its versatility by being extensively utilized across a multitude of sectors, including urban water supply and drainage systems, central heating systems, and drainage networks. Its applications further extend to iron and steel metallurgy companies, oil refineries, paper mills, and power plants. Moreover, it plays a pivotal role in airport construction, chemical plants, textile mills, and sugar mills, while also supporting consumer drainage systems in plant mines. The pump's reliability and efficiency make it an ideal choice for air conditioning systems with water supply needs, as well as agricultural irrigation.
