Detailed Component Features
Between-the-bearings design

Between-the-bearings: Split-case pumps mount the impeller on a shaft supported by bearings on both sides, ensuring stability and reduced vibration.

High-precision casting impeller: Available in cast iron, stainless steel, and bronze to ensure performance across different media.

Sealing Solutions: Traditional packing seals minimize fluid loss using rope-like materials. For more demanding applications, Mechanical seals are preferred for their durability and leak-prevention capabilities.

Sealing System
Flexible Couplings

Flexible Couplings: We use wear-resisting disc or pin couplings. Unlike rigid types, these accommodate vibrations and thermal expansion, protecting shafts and bearings from premature wear.

Frequently Asked Questions
What are the primary advantages of the SOW series split-case design?
The horizontal split-case design allows for easy access to the internal components (bearings, seals, and impeller) without disconnecting the suction or discharge piping, significantly reducing maintenance time.
Which materials are available for the impeller?
We provide high-precision casting impellers in Cast Iron, Stainless Steel, and Bronze to adapt to different chemical properties of the transmission medium.
What is the maximum flow capacity of this pump series?
The SOW series is designed for large-scale operations with a flow range reaching up to 30,000 m³/hr.
Can these pumps handle high-temperature fluids?
The standard medium maximum temperature is ≤80°C. For specific high-temperature requirements, please consult our technical team for custom configurations.
Are different motor voltages supported?
Yes, the system supports a wide range of voltages including 380V, 415V, 3.3KV, 6KV, and 10KV to meet various industrial power standards.
How does the double-suction impeller improve performance?
The double-suction design balances axial forces automatically, which reduces the load on the bearings and increases the overall efficiency and lifespan of the pump.
