Introducing the IH end-suction pump, a pinnacle of engineering excellence. This single-stage, single-suction (axial suction) cantilever centrifugal pump is expertly crafted to convey corrosive liquids with a viscosity akin to water, while eliminating solid particles. It adheres to the prestigious ISO2858 international standards, ensuring unparalleled quality. The IH pump stands out with its extensive performance range, remarkable efficiency, and effortless maintenance. On average, it boasts a 5% improvement in efficiency over the traditional F-type pump, marking it as a globally recognized energy-saving marvel.
The IH chemical pump excels in versatility, with a transmission medium temperature range of -20 ºC to 105 ºC. It is capable of transporting higher temperature media with enhanced cooling measures when required. This pump is indispensable across a multitude of industries, including chemical processing, petroleum, metallurgy, electric power, paper production, food processing, pharmaceuticals, and synthetic fibers. It adeptly handles various corrosive mediums similar to water, ensuring zero pollution and maintaining the integrity of your processes.
Main Design Features
Expertly designed for high-pressure applications, the IH pump comes equipped with robust flanges in PN 10 and PN 16.
Our innovative "Back pull-out" design allows for seamless maintenance, enabling you to remove hydraulic components without detaching the pump body from the plant piping. This feature ensures minimal downtime and maximized operational efficiency.
The dynamically balanced closed impeller is meticulously engineered to minimize radial loads, providing a smooth and stable rotation of the impeller, ensuring a long-lasting, efficient performance.
Crafted with precision, the suction profile is optimized to reduce NPSH, facilitating trouble-free operation even in the most demanding conditions.
The pump features a stainless steel shaft, specifically designed to endure bending-torsion loads, guaranteeing exceptional durability and reliability in your operations.
Equipped with oversized ball bearings, the IH pump offers significantly reduced operating noise and an extended service life, ensuring a quieter and more efficient working environment.
Choose from an extensive selection of mechanical seals or gland packings (SES) tailored to meet the specific requirements of your fluid characteristics and operational conditions, ensuring optimal performance and adaptability.

To achieve the perfect balance of axial thrust, our design incorporates wear rings both at the front and rear of most impellers. The back shroud includes a strategically placed balance hole. However, in cases where the pump's axial thrust is minimal, these features become optional, ensuring maximum efficiency without unnecessary components.
Our impellers, crafted with high-precision casting, guarantee superior performance and are available in robust materials such as cast iron, gleaming stainless steel, and lustrous bronze.
The packing pump cover is fitted with high-quality stuffing suited for a soft packing seal. This design allows water to be introduced under pressure, providing essential seal cooling, lubrication, and cleaning, ensuring optimal performance and longevity.
Offering a choice between single and double mechanical seals, our pumps are engineered for versatility. The introduction of pressurized water into the seal cavity reduces friction and enhances cooling. Designed to ISO3069 standards, our sealed cavities can adapt to various configurations, including mechanical seals with corrugated pipes and expeller seals, for tailored applications.
Flexible Couplings
Unlike their rigid counterparts, flexible couplings are designed to absorb movement such as vibrations and thermal expansion, protecting your system from potential damage. They are perfect for applications where unavoidable misalignment exists between the drive and pump shafts. By dampening vibrations, they also help reduce operational noise. Although more complex and costly, the long-term maintenance savings from protecting shafts and bearings make flexible couplings a wise investment.
To enhance durability and performance, we employ wear-resisting disc couplings or precision-engineered pin couplings, tailored for your specific needs.
