Between-the-bearings: The innovative engineering of split-case pumps, often described as "between-the-bearings," is a testament to their superior design. This configuration features the impeller expertly mounted on a shaft, robustly supported by bearings on both sides, ensuring optimal stability and performance.

Double-suction impeller: Distinguished as the only common pump type with a double-suction impeller, split-case pumps stand out in the crowd. This unique design significantly reduces the load placed on bearings, compared to single-suction configurations, offering enhanced durability and reliability by drawing water efficiently from both sides of the impeller.

Crafted with precision, the high-precision casting impeller guarantees top-tier performance. Available in cast iron, stainless steel, and bronze, each crafted material ensures superior quality and longevity, meeting diverse operational needs with excellence.

 

Packing seals: A time-tested sealing solution, packing seals have been widely implemented for their simplicity and effectiveness. These rope-like materials encircle the pump shaft, adeptly filling gaps to minimize fluid loss. However, over time, wear can increase fluid escape, potentially impacting proper lubrication and ease of replacement.

Mechanical seals: Favored for their superior performance, mechanical seals provide an advanced alternative to traditional packing seals, especially in applications where preventing leakage is critical. Engineered to endure rigorous conditions, these seals utilize multiple sealing points, confidently minimizing leakage and ensuring lasting durability.

 

Flexible couplings
Flexible couplings offer remarkable versatility, accommodating movements such as vibrations and thermal expansion without incurring damage. Ideal for situations where misalignment between drive and pump shafts is unavoidable, they also help in reducing operational noise by absorbing vibrations. Although they feature a more complex and costly design, the long-term benefits include reduced maintenance costs due to their ability to protect shafts and bearings from damage and premature wear.

We incorporate advanced wear-resisting disc or pin couplings, engineered for maximum resilience and performance.
