Between-the-bearings: Split-case pumps define engineering excellence by utilizing the 'between-the-bearings' design. This innovative setup mounts the impeller on a shaft, meticulously supported by bearings on both sides, ensuring unparalleled stability and efficiency.
Double-suction impeller: Unique to split-case pumps, the double-suction impeller is a hallmark innovation that significantly reduces bearing loads. Unlike traditional designs that draw water from a single side, this advanced impeller design optimizes performance by drawing in water from both sides.
Our high-precision casting impeller, crafted from premium materials such as cast iron, stainless steel, and bronze, guarantees superior performance and durability, making it an indispensable component in our pump design.
Packing seals have long been the sealing solution of choice, utilizing robust rope-like materials to wrap around the pump shaft, filling gaps and minimizing fluid loss. However, as these materials wear over time, fluid loss may increase, potentially affecting lubrication and the ease of replacement, which are crucial for optimal performance.
Mechanical seals are the modern solution, favored in applications where leak prevention is paramount. Compared to traditional packing seals, they offer enhanced durability and are engineered to withstand rigorous use. Their multiple sealing points effectively minimize leakage, making them a superior choice in demanding conditions.
Flexible couplings
Flexible couplings excel in accommodating movement, such as vibrations and thermal expansion, unlike their rigid counterparts. Ideal for situations with unavoidable misalignment between drive and pump shafts, they effectively absorb vibrations, reducing operational noise. Though complex and initially costly, their ability to safeguard shafts and bearings results in significant maintenance savings over time.
Our choice of wear-resisting disc or pin couplings ensures long-term reliability and performance, further enhancing the durability of our cutting-edge pump systems.
