Between-the-bearings: Dive into the world of efficiency with our split-case pumps, ingeniously designed as 'between-the-bearings' marvels. This advanced setup mounts the robust impeller on a shaft, artfully supported by bearings on both sides, ensuring optimal performance and longevity.
Double-suction impeller: Unleash the power of split-case technology, the only COMMON pump design equipped with a double-suction impeller. This sophisticated feature significantly reduces the load on the bearings compared to a single-suction impeller, fostering a more balanced and efficient operation.
Our high-precision casting impeller guarantees exceptional performance, crafted meticulously from premium materials such as cast iron, stainless steel, and bronze, ensuring durability and reliability for every application.
Packing seals have reigned as the go-to sealing solution for decades, utilizing rope-like materials to embrace the pump shaft snugly. While efficient initially, these seals may show increased fluid loss over time due to wear, potentially affecting lubrication and ease of replacement.
Mechanical seals are the modern-day champions over traditional packing seals, particularly in scenarios where leakage must be avoided. Renowned for their durability, these seals employ multiple sealing points to virtually eliminate leakage, enduring far more rigorous conditions than their older counterparts.
Flexible couplings
In contrast to rigid couplings, flexible couplings shine in their ability to accommodate movement like vibrations and thermal expansion without damage. Ideal for situations with unavoidable misalignment between drive and pump shafts, they adeptly absorb vibrations, reducing operational noise. Though more complex and costly, the design preserves shafts and bearings from harm and wear, offering maintenance savings over time.
Our commitment to quality is evident in our use of wear-resisting disc or pin couplings, ensuring superior performance and longevity.
Our Reliable Water Pump with Split-Casing is the epitome of versatility and efficiency, finding its place in a myriad of critical applications.
