Between-the-Bearings Excellence: Split-case pumps are renowned as 'between-the-bearings' champions. This design strategically mounts the impeller on a shaft, elegantly supported by robust bearings on both sides, ensuring enhanced stability and performance.
Double-Suction Impeller Innovation: Split-case pumps stand alone as the only COMMON pump variant featuring an advanced double-suction impeller. This ingenious design significantly reduces the load on bearings compared to conventional single-suction impellers, which draw water from just one side.
High-Precision Casting Impeller: Engineered to perfection, our high-precision casting impellers assure outstanding performance. Available in cast iron, stainless steel, and bronze, they promise durability and reliability.
Packing Seals: For years, packing seals have been the go-to solution, using rope-like materials to wrap around the pump shaft. They fill gaps to minimize fluid loss; however, as wear and tear set in, fluid loss can increase, affecting lubrication and ease of replacement, crucial for optimal function.
Mechanical Seals: In modern applications, where avoiding leakage is paramount, mechanical seals outperform traditional packing seals. Crafted for durability, they feature multiple sealing points to almost entirely eradicate leakage concerns.
Flexible Couplings
Flexible Coupling Advantages: Unlike their rigid counterparts, flexible couplings deftly handle movement, such as vibrations and thermal expansion. Ideal for scenarios with unavoidable misalignment, they absorb vibrations, reducing noise. Although their design is more complex and costly, the protection they offer to shafts and bearings from damage and premature wear results in significant maintenance savings over time.
Wear-Resisting Couplings: Our selection includes wear-resisting disc couplings or pin couplings, designed for robust performance.
