The IH end-suction pump is a cutting-edge, single-stage, single-suction (axial suction) cantilever centrifugal pump, expertly designed for conveying corrosive liquids with a viscosity comparable to water, ensuring no solid particles are present. It proudly adheres to international standards ISO2858 for mark, rated performance, and size. This pump showcases an impressive range of performance capabilities, exceptional efficiency, and remarkably easy maintenance. Its efficiency is an average of 5 percent higher compared to the traditional F-type pump, making it a globally recognized and promoted energy-saving solution.
The transmission medium temperature of the IH chemical pump ranges from -20 ºC to 105 ºC, with the capability to handle even higher temperatures through improved cooling measures when needed. This makes it ideal for industries such as chemical processing, petroleum refining, metallurgy, electric power, paper production, food and beverage, pharmaceuticals, and synthetic fiber manufacturing. It is designed to transport a variety of corrosive media that are similar to water, without causing any pollution.
Main Design Features
Exceptionally suited for high-pressure applications, our pump features robust flanges available in PN 10 and PN 16.
With an innovative "Back pull-out" design, it allows for the effortless removal of hydraulic components without disconnecting the pump body from the plant pipes, ensuring seamless maintenance.
A dynamically balanced closed impeller is incorporated to minimize radial loads, guaranteeing smooth and efficient impeller rotation.
The suction profile is meticulously crafted to reduce NPSH, facilitating trouble-free operation even in the most demanding conditions.
Designed with a resilient stainless steel shaft, it is engineered to withstand significant bending-torsion loads, enhancing durability.
Equipped with oversized ball bearings, the pump significantly reduces working noise and extends its service life, providing reliability and comfort.
Offering a comprehensive selection of mechanical seals or gland packings (SES), the pump is configured to meet the unique requirements of fluid characteristics and operating conditions, ensuring optimal performance.

To effectively balance axial thrust, our design includes wear rings both at the front and back of most impellers, with a balance hole strategically positioned on the back shroud. For pumps where axial thrust is minimal, the design smartly omits the rear wear ring and balance hole, optimizing performance efficiently.
Our high-precision casting impeller is masterfully crafted to guarantee top-notch performance. Available in durable materials such as cast iron, stainless steel, and bronze, it ensures reliability and longevity.
The pump cover equipped with a packing seal is ingeniously designed for soft packing applications, allowing water under certain pressure to pass through for efficient seal cooling, lubrication, and cleaning.
Offering both single and double mechanical seals, our system allows water under controlled pressure to enter the seal cavity, effectively rinsing the end surface to reduce friction and provide cooling. With the flexibility to accommodate ISO3069 standards, our design includes options like a mechanical seal with a corrugated pipe and an expeller seal for specific requirements.
Flexible Couplings
Designed to outperform rigid couplings, our flexible couplings adeptly handle movement such as vibrations and thermal expansion, preventing damage. Ideal for scenarios with inherent misalignment between drive and pump shafts, they excel at absorbing vibrations and minimizing operational noise. Although their sophisticated design may entail higher costs, the long-term benefits include significant maintenance savings as they protect shafts and bearings from damage and early wear.
Our solutions utilize wear-resistant disc couplings or pin couplings, ensuring durability and optimal performance.
