The IH end-suction pump stands out as a single-stage, single-suction (axial suction) cantilever centrifugal pump, meticulously crafted for conveying corrosive liquids with a viscosity akin to water, free from solid particles. Designed to meet the prestigious international ISO2858 standards, this pump showcases an impressive array of characteristics including an expansive performance range, remarkable efficiency, and straightforward maintenance. On average, it boasts a 5% higher efficiency compared to the conventional F-type pump, making it a beacon in international energy-saving initiatives.
The IH chemical pump excels in versatility with its medium transmission temperature range from -20 ºC to 105 ºC. It's adaptable for higher temperature mediums with enhanced cooling measures if required, making it suitable for a diverse range of industries including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber sectors. It is designed to transport various corrosive media that resemble water without causing pollution, embodying reliability and efficiency.
Main Design Features
Expertly engineered for high-pressure applications, the pump features robust flanges in PN 10 and PN 16, ensuring reliable performance under demanding conditions.
With its innovative "Back pull-out" design, this pump allows for the convenient removal of hydraulic components without detaching the pump body from the plant pipes, streamlining maintenance processes.
Equipped with a dynamically balanced closed impeller, the pump minimizes radial loads and ensures the smooth, uninterrupted rotation of the impeller, enhancing operational stability.
The suction profile is meticulously designed to minimize NPSH, enabling trouble-free operation even in the most challenging of conditions, offering peace of mind and reliable performance.
Crafted from stainless steel, the shaft is precisely engineered to endure bending-torsion loads, ensuring durability and long-lasting performance.
Oversized ball bearings are incorporated to significantly reduce operational noise and extend the service life of the pump, contributing to a quieter, more efficient work environment.
Offering a wide array of mechanical seals or gland packings (SES), this pump can be configured to meet the specific requirements of fluid characteristics and usage conditions, ensuring optimal performance tailored to your needs.

To impeccably balance axial thrust, our innovative design includes wear rings strategically placed at both the front and rear of the impeller for a majority of models. The balance hole is ingeniously positioned on the back shroud of the impeller. For certain pumps where axial thrust is minimal, the need for a rear wear ring and balance hole is gracefully eliminated.
Our high-precision casting impeller is crafted to excellence, guaranteeing unparalleled performance. Choose from premium materials including cast iron, stainless steel, and bronze, tailored to ensure the utmost reliability and durability.
The packing pump cover is meticulously fitted with stuffing designed for a soft packing seal. This ingenious setup allows a controlled pressure of water to pass through, providing essential seal cooling, lubrication, and cleaning, upholding the pump's efficiency and longevity.
For the mechanical seal, we offer both single and dual mechanical seal options. A precisely controlled water pressure enters the seal cavity, effectively rinsing the end surface to minimize friction and deliver an exceptional cooling effect. Depending on your needs, the seal cavity can be adapted to accommodate ISO3069 standards with structures such as the sophisticated corrugated pipe mechanical seal and the efficient expeller seal.
Flexible Couplings
Flexible couplings stand out against their rigid counterparts by accommodating some degree of movement, such as vibrations and thermal expansion, without incurring any damage. They are the perfect choice for scenarios where unavoidable misalignment exists between drive and pump shafts. Their superior vibration absorption not only reduces excessive operating noise but also comes with a more intricate, albeit costlier, design. Nevertheless, their ability to safeguard shafts and bearings from damage and premature wear ultimately results in significant maintenance savings over time.
Our selection includes wear-resistant disc couplings and pin couplings, offering you robust solutions for your demanding applications.
