Between-the-Bearings: Discover the engineering marvel that is the split-case pump, a true 'between-the-bearings' masterpiece. Ingeniously designed, its impeller is mounted on a shaft with bearings gracefully supporting both sides, ensuring robust, balanced performance.
Double-Suction Impeller: Dive into the uniqueness of split-case pumps, celebrated for their exclusive double-suction impeller design. This ingenious feature dramatically reduces loads on bearings, compared to single-suction impellers that draw water from only one side. Experience the benefits of enhanced durability and efficiency.
High-Precision Casting: Elevate performance with our impeccably crafted impeller, available in the finest materials—cast iron, stainless steel, and bronze. Each piece is a testament to precision, ensuring supreme performance and reliability.
Packing Seals: For generations, packing seals have been the go-to solution for sealing needs, employing rope-like materials that carefully encase the pump shaft. While effective, they naturally wear over time, potentially leading to increased fluid loss and challenges with lubrication and replacement. Choose wisely for optimal performance.
Mechanical Seals: In applications where leakage is not an option, mechanical seals reign supreme. Engineered for durability, they withstand rigorous conditions far better than traditional seals. With multiple sealing points, they nearly eradicate leakage, offering peace of mind and reliability in every operation.
Flexible Couplings
Flexible Couplings: Unlike their rigid counterparts, flexible couplings excel in adapting to movement, such as vibrations and thermal expansion. Perfect for scenarios with inevitable misalignments, they also reduce noise. While their design may be more complex and costly, the long-term maintenance savings and protection offered to shafts and bearings make them an invaluable investment.
We employ premium wear-resisting disc or pin couplings to ensure enduring performance.
