Between-the-bearings: Discover the engineering marvel of our split-case pumps, known as 'between-the-bearings' pumps. This innovative design positions the impeller on a shaft that is securely supported by robust bearings on both sides. This ensures enhanced stability and efficient performance, making our pumps a reliable choice for your needs.
Double-suction impeller: Our split-case pumps boast the distinction of being the only common pump type equipped with a double-suction impeller. This advanced feature dramatically reduces the loads imposed on the bearings compared to traditional single-suction designs. Experience superior efficiency and longevity with our innovative impeller technology.
Our high-precision casting impeller is a testament to performance excellence, crafted from premium materials such as cast iron, stainless steel, and bronze. This ensures unparalleled durability and reliability, providing you with peace of mind that your operations will run smoothly and efficiently.
Packing seals have long been the stalwart of sealing solutions, utilizing rope-like materials that snugly wrap around pump shafts, filling voids to minimize fluid loss. However, as time progresses, the gland packing may wear, increasing fluid loss, potentially affecting lubrication, and complicating replacement. Stay ahead with our cutting-edge sealing strategies.
In modern applications where leakage must be avoided, mechanical seals outshine traditional packing seals. With superior durability and design, our mechanical seals offer multiple sealing points to virtually eradicate leakage issues, providing robust protection and peace of mind across diverse uses.
Flexible couplings
Discover the advantages of flexible couplings, engineered to accommodate movement such as vibrations and thermal expansion without incurring damage. Ideal for applications with unavoidable shaft misalignment, they absorb vibrations to reduce operating noise. While more intricate and costly, the long-term savings in maintenance, due to their protective role in shielding shafts and bearings, are significant.
We utilize wear-resistant disc coupling or pin coupling, ensuring maximum durability and performance.
