Single-stage double-suction volute axial centrifugal pump, horizontal installation, driver (motor or engine) may be set on the left or right side of the pump (ie, outlet-oriented, the driver is counterclockwise in the left side, clockwise in the right side). |
Between-the-bearings: Split-case pumps are ingeniously engineered as "between-the-bearings" pumps. This clever design secures the impeller on a robust shaft, meticulously supported by bearings on both sides of the impeller, ensuring unparalleled stability and efficiency.
Double-suction impeller: Split-case pumps stand out as the only COMMON pump type boasting a highly efficient double-suction impeller. This advanced impeller design significantly reduces the strain on the bearings compared to a conventional single-suction impeller, which only draws water from one side.
Experience the excellence of high-precision casting impellers, designed to optimize performance. Crafted from quality materials such as cast iron, stainless steel, and bronze, these impellers promise durability and superior functionality.
Packing seals have long been the go-to sealing solution, utilizing rope-like materials that snugly fit around the pump shaft, effectively curbing fluid loss. Over time, as the gland packing wears, fluid loss may rise, disrupting lubrication and complicating replacements. Keeping it updated ensures optimal performance.
In modern applications where preventing leakage is paramount, mechanical seals are the preferred choice over traditional packing seals. These seals are renowned for their exceptional durability and resilience, expertly crafted to withstand rigorous conditions. With multiple sealing points, they drastically minimize leakage issues.
Flexible couplings
Flexible couplings, unlike their rigid counterparts, are expertly crafted to accommodate slight movements like vibrations and thermal expansion without incurring damage. This makes them indispensable for applications with inevitable misalignments between drive and pump shafts. Beyond flexibility, they effectively dampen vibrations and operating noise, although they incur a more complex, costly design. Nonetheless, they safeguard shafts and bearings from damage, offering long-term maintenance savings.
Our selection includes wear-resistant disc couplings or pin couplings, ensuring efficiency and durability.
