Equipped with a double-suction impeller, this pump minimizes axial force, enhancing its operational efficiency. Using advanced CAD hydraulic modeling, it achieves an optimal design that guarantees outstanding performance. The incorporation of a prototype impeller, alongside the option for a modified impeller, allows adaptation to various working conditions, significantly boosting efficiency.
Crafted with precision, the pump's double volute design effectively reduces radial forces, ensuring minimal bearing stress and extending lifespan. Installation is simplified with automatic pump cover calibration, and the relative positioning of the motor’s and pump’s inlets and outlets can be adjusted to meet site-specific requirements. The pump operates without swirl at the inlet, ensuring smooth performance and minimal loss. Precision casting ensures the pump casing and impeller surfaces are remarkably smooth, providing superior anti-cavitation properties and high efficiency.

Revolutionary Between-the-Bearings Design: Our split-case pumps embody the exclusive 'between-the-bearings' architecture. This innovation mounts the impeller on a shaft held firmly by bearings on each side, ensuring stability and precision.
Ingenious Double-Suction Impeller: Unique to split-case pumps, our double-suction impeller significantly reduces bearing loads compared to single-suction designs, enhancing performance and reliability for all your needs.
Exquisite High-Precision Casting: Our impellers, crafted from top-grade cast iron, stainless steel, or bronze, guarantee exceptional performance and durability, catering to your specific requirements.
Traditional Packing Seals: Time-tested packing seals utilize robust rope-like materials to securely wrap around the pump shaft, minimizing fluid loss. Although effective, they may wear over time, increasing fluid loss and complicating maintenance.
Advanced Mechanical Seals: Choose mechanical seals for superior durability and leak prevention. These modern seals feature multiple sealing points, offering robust protection and enduring resilience in demanding applications.
Flexible Couplings
Dynamic Flexible Couplings: Designed to accommodate essential movement like vibrations and thermal expansion, flexible couplings ensure seamless operation. Though more complex and costly, they deliver maintenance savings by preventing premature wear and reducing operating noise.
Durable Coupling Choices: Opt for our wear-resisting disc or pin couplings for enhanced performance and longevity.
