Between-the-Bearings: Embrace the epitome of engineering elegance with our Split-case Pumps, renowned as "between-the-bearings" marvels. These pumps feature a meticulously mounted impeller on a robust shaft, gracefully supported by bearings on both sides, ensuring optimal balance and efficiency.
Double-Suction Impeller: Our Split-case Pumps stand out as the quintessential choice, being the only common pump type equipped with a sophisticated double-suction impeller. This innovative design significantly reduces the load on bearings compared to the traditional single-suction impellers, elevating performance and longevity.
Our high-precision casting impeller is the cornerstone of unwavering performance, crafted meticulously in materials such as cast iron, stainless steel, and bronze to meet diverse demands with reliability and durability.
Packing Seals: For decades, packing seals have been the go-to sealing solution. These seals employ durable, rope-like materials that snugly wrap around the pump shaft, effectively filling dead space to minimize fluid loss. However, as time passes, the gland packing material may wear down, leading to increased fluid loss, impaired lubrication, and potentially hindering ease-of-replacement.
Mechanical Seals: In modern applications where leakage is not an option, mechanical seals reign supreme over traditional packing seals. Renowned for their durability, these advanced seals are crafted to endure rigorous conditions. With multiple sealing points, they ensure leakage issues are virtually eliminated, guaranteeing seamless operation.
Advanced Flexible Couplings
Unlike their rigid counterparts, flexible couplings are engineered to gracefully accommodate movement, such as vibrations and thermal expansion, without incurring damage. Ideal for settings where unavoidable misalignment occurs between drive and pump shafts, these couplings excel in absorbing vibrations and reducing operating noise. While their sophisticated design may be more complex and costly, the long-term maintenance savings due to protection of shafts and bearings from damage and wear make them an invaluable investment.
We implement wear-resisting disc or pin couplings for superior performance.
