Between-the-bearings: Experience the superior engineering of split-case pumps, known as 'between-the-bearings' pumps. This innovative design mounts the impeller on a shaft supported by bearings on both sides, providing unrivaled stability and performance.
Double-suction impeller: Discover the exclusive advantage of split-case pumps featuring the unique double-suction impeller. This design significantly reduces the load on bearings compared to single-suction impellers, ensuring a longer-lasting and more efficient operation.
The high-precision casting impeller ensures outstanding performance and durability, crafted from premium materials such as cast iron, stainless steel, and bronze, tailored to meet your demanding standards.
Packing seals have been the go-to sealing solution for years, utilizing rope-like materials that encircle the pump shaft to minimize fluid loss. Although effective, the gland packing may wear over time, potentially increasing fluid leakage and affecting lubrication or ease of replacement.
Embrace the advantages of mechanical seals preferred in various applications where leakage is a concern. These modern seals are more robust than traditional options, featuring multiple sealing points to nearly eradicate any leakage issues, providing reliability and peace of mind.
Flexible couplings
Flexible couplings offer unmatched versatility compared to rigid couplings, accommodating vibrations and thermal expansions without damage. Ideal for scenarios with unavoidable misalignment, they absorb vibrations to reduce noise, although they come with a more complex and costly design. Their ability to protect shafts and bearings from damage results in significant maintenance savings over time.
We proudly utilize wear-resisting disc coupling or pin coupling, ensuring durability and optimal performance in even the most challenging conditions.
