Between-the-bearings: Our state-of-the-art split-case pumps are expertly designed as "between-the-bearings" pumps. This sophisticated configuration mounts the impeller securely on a shaft, which is brilliantly supported by robust bearings on both sides, ensuring stability and superior performance.
Double-suction impeller: These split-case pumps stand out as the premier COMMON pump type featuring a double-suction impeller. This innovative design imposes significantly fewer loads on the bearings compared to traditional single-suction models, which draw water from only one side of the impeller, ensuring enhanced efficiency and longevity.
Our high-precision casting impeller guarantees unmatched performance, available in top-grade materials such as cast iron, stainless steel, and bronze, catering to diverse demanding applications with resilience.
Traditional packing seals have long been revered as the preferred sealing solution, employing rope-like materials that snugly wrap around the pump shaft to fill dead space and minimize fluid loss. However, fluid loss may amplify over time as the gland packing material wears down, potentially impairing regular lubrication and reducing the ease of replacement that is vital for optimal functionality.
Mechanical seals are the modern marvel preferred over traditional packing seals for an array of applications where leakage issues must be rigorously avoided. These durable seals are engineered to endure far more rigorous conditions, utilizing multiple sealing points to virtually eliminate leakage concerns.
Superior Flexible Couplings
Distinct from rigid couplings, our flexible couplings are designed to handle movement, such as vibrations and thermal expansion, without compromising performance. Perfect for applications with unavoidable misalignment between drive and pump shafts, they also serve to reduce excessive noise by absorbing vibrations. While their design is more complex and costly, the long-term maintenance savings, due to the protection they offer to the shaft and bearings from damage, make them an invaluable investment.
We integrate high-performance wear-resisting disc coupling or pin coupling, ensuring maximum durability and efficiency.
