The IH end-suction pump, a marvel of engineering, stands as a single-stage, single-suction (axial suction) cantilever centrifugal pump. It is masterfully crafted to convey corrosive liquids possessing a viscosity akin to water, devoid of solid particles. Designed in exact accordance with the esteemed international standards ISO2858, this pump offers a vast array of performance benefits. Its hallmark features include an extensive performance range, remarkable efficiency, and effortless maintenance. In fact, its efficiency outshines the F-type pump by an average of 5 percent, making it a globally acclaimed energy-saving product.
The IH chemical pump is a versatile powerhouse, adept at withstanding transmission medium temperatures that range from -20 ºC to 105 ºC. It possesses the capability to transport mediums of even higher temperatures when enhanced with superior cooling measures, if necessary. This pump finds its niche in diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fibers. It is expertly designed to transport a variety of corrosive media, analogous to water, without pollution.
Main Design Features
Built to excel in high-pressure applications, this pump is equipped with flanges available in PN 10 and PN 16.
The innovative 'back pull-out' design facilitates the removal of hydraulic components seamlessly, eliminating the need to detach the pump body from the plant pipes.
Featuring a dynamically balanced closed impeller, the pump minimizes radial loads and ensures the seamless rotation of the impeller.
The suction profile is meticulously crafted to reduce NPSH, ensuring flawless operation even under demanding conditions.
The stainless steel shaft is meticulously engineered to endure bending-torsion loads, demonstrating exceptional durability.
Oversized ball bearings are employed to significantly reduce working noise while extending the service life of the pump.
An expansive selection of mechanical seals or gland packings (SES) is available, tailored to meet the specific requirements dictated by the fluid characteristics and usage conditions.

To expertly counterbalance axial thrust, our pump design features strategically placed wear rings at both the front and the back of the impeller. Additionally, a balance hole is elegantly situated on the back shroud of the impeller. In pumps where axial thrust is minimal, these components may not be necessary, offering a streamlined and efficient design.
Our high-precision casting impellers are designed to ensure superior performance. Available in robust materials like cast iron, stainless steel, and bronze, these impellers promise durability and reliability, making them an excellent choice for diverse applications.
The packing pump cover is innovatively equipped with stuffing designed for a soft packing seal. This allows for the circulation of pressurized water, facilitating seal cooling, lubrication, and cleaning to enhance performance and longevity.
Our range includes both single and double mechanical seals, each optimized to introduce pressurized water into the seal cavity, effectively rinsing away friction on the end surface and providing a cooling effect. According to specific needs, the sealed cavity can be customized to ISO3069 standards, accommodating advanced structures such as mechanical seals with corrugated pipes and expeller seals.
Flexible couplings
Flexible couplings, unlike their rigid counterparts, are engineered to handle slight movements such as vibrations and thermal expansions without sustaining damage. This adaptability makes them perfect for applications with unavoidable misalignments between drive and pump shafts. Additionally, their ability to absorb vibrations helps in significantly reducing operating noise. While their design is inherently more complex and costly, the protection they provide to shafts and bearings against damage and premature wear translates to substantial maintenance savings over time.
We employ durable wear-resisting disc couplings or pin couplings as part of our sophisticated pump systems.
