The IH end-suction pump is a marvel of engineering—a single-stage, single-suction (axial suction) cantilever centrifugal pump, masterfully designed to convey corrosive liquids with a viscosity akin to water, all while excluding solid particles. This pump boasts compliance with international standards ISO2858, ensuring exemplary performance, reliable efficiency, and effortless maintenance. With an average efficiency increase of 5% over the F-type pump, this pump is an exemplar of energy-saving innovation, championed on the global stage.
The IH chemical pump is designed to handle transmission medium temperatures ranging from -20 ºC to 105 ºC. With enhanced cooling measures, it can even manage higher temperatures, making it an ideal choice for diverse applications in chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber industries. It is perfectly suited to transport various corrosive media, akin to water, without any pollution.
Main Design Features
Engineered for high-pressure applications, this pump accommodates flanges in both PN 10 and PN 16, ensuring versatility and robustness in demanding environments.
The innovative 'back pull-out' design of this pump allows the hydraulic components to be removed effortlessly, without detaching the pump body from the plant pipes, revolutionizing maintenance processes.
Featuring a dynamically balanced closed impeller, this pump minimizes radial loads, ensuring the impeller spins with unparalleled smoothness and stability.
The carefully crafted suction profile is optimized to reduce NPSH, guaranteeing trouble-free operation even under the most challenging conditions.
Constructed with a robust stainless steel shaft, this pump is built to withstand the rigors of bending-torsion loads, promising durability and reliability.
Equipped with oversized ball bearings, this pump delivers reduced operational noise and extends the service life, providing a whisper-quiet experience.
Offering an extensive selection of mechanical seals or gland packings (SES), this pump can be tailored to meet the specific fluid characteristics and usage conditions, ensuring optimal performance and adaptability.

To expertly balance axial thrust, our advanced design features wear rings positioned both at the front and rear of most impellers, complemented by a strategically placed balance hole on the back shroud of the impeller. For some pumps where the axial thrust remains minimal, the engineering design cleverly omits the rear wear ring and balance hole for optimized performance.
Our high-precision casting process delivers impellers that guarantee exceptional performance, crafted meticulously from premium materials including cast iron, stainless steel, and bronze, ensuring durability and reliability in every pump operation.
The pump cover, enhanced with a robust packing seal, incorporates stuffing that facilitates a soft packing seal solution. This ingenious design allows for the introduction of a controlled water pressure, ensuring effective seal cooling, lubrication, and cleaning, thereby enhancing the pump's operational longevity.
Offering versatility in mechanical seal options, our pumps boast both single and double mechanical seals. By introducing a regulated water pressure into the seal cavity, they efficiently rinse the end surface friction while providing a vital cooling effect. Tailored to demands, our design accommodates ISO3069 specified structures, including the innovative use of mechanical seals with corrugated pipes and expeller seals, for a customizable sealing solution.
Flexible couplings
Designed for adaptability, flexible couplings accommodate movement such as vibrations and thermal expansion without sustaining damage, making them perfect for scenarios with unavoidable misalignment between drive and pump shafts. Their ability to absorb vibrations translates to reduced operational noise. Despite a more intricate and costlier design, the long-term maintenance savings are significant, as they extend the life of shafts and bearings by preventing damage and premature wear.
Our selection of robust wear-resistant disc and pin couplings ensures optimal durability and performance, tailored to withstand the rigors of demanding pump applications.
