The IH end-suction pump is a marvel of modern engineering, representing a single-stage, single-suction (axial suction) cantilever centrifugal pump. It is expertly crafted to handle corrosive liquids with viscosities akin to water, all while ensuring that no solid particles interfere. Its hallmark features include adherence to international ISO2858 standards for marking, rated performance, and size, positioning this pump as a leader in efficiency and maintenance ease. With performance ranges that cater to diverse needs and a remarkable efficiency boost of up to 5% over traditional F-type pumps, this is a globally celebrated energy-saving solution.
Designed for versatility, the IH chemical pump can handle transmission medium temperatures ranging from -20 ºC to 105 ºC. For applications demanding even higher temperatures, enhanced cooling measures can be introduced. This adaptability makes it an ideal choice for industries such as chemical processing, petroleum refining, metallurgy, electric power generation, paper manufacturing, food production, pharmaceuticals, and synthetic fiber production. It is adept at transporting a variety of corrosive media that are similar to water, all without causing any pollution.
Main Design Features
Engineered for excellence, this pump is perfectly fitted for high-pressure applications, compatible with flanges in PN 10 and PN 16.
The innovative 'Back pull-out' design allows for hassle-free removal of hydraulic components without disturbing the pump's connection to plant pipes, ensuring zero downtime and maintenance ease.
A dynamically balanced closed impeller minimizes radial loads, ensuring the impeller rotates smoothly and efficiently for optimal performance.
The suction profile is meticulously designed to reduce NPSH, ensuring seamless and trouble-free operation even under the most demanding conditions.
Crafted from robust stainless steel, the shaft is built to withstand substantial bending-torsion loads, ensuring durability and reliability.
Oversized ball bearings are utilized to greatly reduce operating noise and extend the overall service life of the pump, promising a quieter and longer-lasting solution.
With a vast selection of mechanical seals or gland packings (SES) available, configurations can be tailored to perfectly match the fluid characteristics and specific use conditions, ensuring optimal performance.

To expertly balance axial thrust, our design incorporates wear rings both at the front and rear of most impellers, complemented by a balance hole located on the impeller's back shroud. For certain pumps with minimal axial thrust, the sophisticated engineering eliminates the need for rear wear rings and balance holes.
Our impellers, crafted with high-precision casting, guarantee exceptional performance. Available in robust materials like cast iron, stainless steel, and bronze, they ensure durability and efficiency.
The packing pump cover is equipped with premium stuffing, designed for a reliable soft packing seal. This innovative stuffing allows the controlled passage of pressurized water for enhanced seal cooling, lubrication, and cleaning.
Our mechanical seals come in two versatile types: single and double. By channeling water under precise pressure into the seal cavity, friction on the end surface is minimized while ensuring effective cooling. Customization is key, and our seals can adapt to ISO3069 standards or feature structures like corrugated pipe mechanical seals and expeller seals, tailored to your specifications.
Advanced Flexible Couplings
Unlike their rigid counterparts, flexible couplings adeptly manage slight movements—such as vibrations and thermal expansions—without sustaining damage. Perfect for applications with minor misalignments between drive and pump shafts, they excel in vibration absorption and noise reduction. Although they feature a more intricate, costlier design, their capacity to protect shafts and bearings from damage and premature wear results in significant maintenance savings over time.
We proudly utilize wear-resistant disc couplings or pin couplings for enhanced durability and performance.
