IH end-suction pump is a marvel of engineering, featuring a single-stage single-suction (axial suction) cantilever centrifugal design. It's expertly crafted to transport corrosive liquids with water-like viscosity, free of solid particles. Conforming to international standards ISO2858, it boasts a wide range of performance, high efficiency, and ease of maintenance. Compared to the F-type pump, its efficiency is elevated by an impressive 5%, making it a leading choice in global energy-saving innovations.
With a transmission medium temperature range of -20 ºC to 105 ºC, the IH chemical pump is versatile enough to handle higher temperatures with improved cooling measures if needed. It is ideal for diverse sectors such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers, effectively transporting a variety of corrosive fluids akin to water without contamination.
Main design features
Engineered for high-pressure applications, our pump is equipped with robust flanges in PN 10 and PN 16 to meet your demanding requirements.
The innovative 'Back pull-out' design facilitates the removal of hydraulic components without detaching the pump body from the plant pipes, ensuring seamless maintenance.
Its dynamically balanced closed impeller is meticulously designed to minimize radial loads, delivering smooth and flawless impeller rotation.
The suction profile is ingeniously crafted to lower NPSH, ensuring trouble-free operation even under the most demanding conditions.
The stainless steel shaft is engineered to endure bending-torsion stresses, reflecting a commitment to superior durability and performance.
Oversized ball bearings are integrated to deliver reduced operational noise and extended service life, underscoring reliability and user satisfaction.
Enjoy a broad selection of mechanical seals or gland packings (SES), meticulously configured to align with the fluid's unique characteristics and usage conditions.

To masterfully balance axial thrust, most of our pumps are ingeniously designed with both front and rear wear rings around the impeller. Additionally, the balance hole is strategically located on the back shroud of the impeller. In some uniquely designed pumps where the axial thrust is minimal, the need for a rear wear ring and balance hole has been skillfully eliminated, showcasing our commitment to efficiency and innovation.
Our high-precision casting impeller is meticulously crafted to ensure optimal performance. Available in robust materials such as cast iron, stainless steel, and bronze, these impellers provide unparalleled durability and reliability, catering to diverse application needs with excellence.
The packing pump cover comes expertly equipped with stuffing for a soft packing seal. This ingenious design allows the stuffing to channel water under certain pressure for effective seal cooling, lubrication, and cleaning, enhancing both performance and longevity.
For mechanical seals, we offer two sophisticated options: a single mechanical seal and a double mechanical seal. Water is introduced into the seal cavity under precise pressure to cleanse and cool the end surface friction, ensuring optimal performance. Our designs adhere to ISO3069 standards, allowing customization with other structures, such as mechanical seals with corrugated pipes and expeller seals, providing versatility to meet specific demands.
Flexible Couplings
In contrast to rigid couplings, our flexible couplings are expertly engineered to accommodate movements like vibrations and thermal expansions without incurring damage. This makes them an ideal solution for applications where unavoidable misalignment exists between drive and pump shafts. They excel in absorbing vibrations, thereby significantly reducing operational noise. While their design is more complex and costly upfront, the long-term savings on maintenance through protection against shaft and bearing damage are substantial, making them a valuable investment.
We proudly utilize high-quality wear-resisting disc couplings or pin couplings, ensuring exceptional performance and durability.
