Between-the-bearings Excellence: Our split-case pumps epitomize engineering precision with their innovative 'between-the-bearings' design. By mounting the impeller on a shaft supported by robust bearings on both sides, we ensure enhanced stability and longevity.
Revolutionary Double-suction Impeller: Experience the unique advantage of our split-case pumps, the only mainstream pumps featuring a double-suction impeller. This advanced design significantly reduces the loads on bearings compared to traditional single-suction impellers, enhancing efficiency and reliability.
Precision-crafted Impeller: Our high-precision casting impellers, available in cast iron, stainless steel, and bronze, promise unwavering performance and durability, meeting your diverse operational needs.
Traditional Packing Seals: A Time-tested Solution: Known for their reliability, packing seals utilize rope-like materials to wrap around the pump shaft, effectively filling gaps and minimizing fluid loss. Over time, these materials may wear, impacting lubrication and ease-of-replacement.
Durable Mechanical Seals: Choose mechanical seals for superior durability and leak prevention. Built to endure rigorous conditions, these seals offer advanced multi-point sealing solutions to virtually eliminate leakage, making them indispensable for demanding applications.
Versatile Flexible Couplings
Innovative Flexible Couplings: Offering a sophisticated solution for systems with unavoidable misalignment, our flexible couplings adeptly handle vibrations and thermal expansion, preventing damage. They excel in noise reduction and can lead to long-term maintenance savings despite their more complex and costly design.
Advanced Wear-resistant Disc or Pin Coupling: We incorporate state-of-the-art wear-resisting disc or pin couplings into our designs for enhanced protection and prolonged service life.
