The IH end-suction pump represents the epitome of single-stage, single-suction (axial suction) cantilever centrifugal pump technology. Designed for the conveyance of corrosive liquids with viscosities akin to water, this innovative pump efficiently handles fluids without solid particles. Built in compliance with international standards ISO2858, it boasts an impressive array of performance features, including an extensive performance range, exceptional efficiency, and effortless maintenance. Its efficiency surpasses the F-type pump by an average of 5 percent, marking it as a standout member of globally endorsed energy-saving technologies.
Engineered for versatility, the IH chemical pump operates over a transmission medium temperature range of -20 ºC to 105 ºC. With improved cooling measures, it even accommodates higher temperature media, making it ideal for diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber. It adeptly transports all kinds of corrosive media similar to water, ensuring no pollution and reliable performance across applications.
Main Design Features
Crafted for high-pressure scenarios, featuring robust flanges available in PN 10 and PN 16, this pump is engineered to withstand demanding conditions.
Innovatively designed with a "Back pull-out" feature, this pump allows seamless removal of hydraulic components without detaching the pump body from the plant pipes, ensuring maximum convenience.
Equipped with a dynamically balanced closed impeller, the design minimizes radial loads and guarantees smooth, reliable impeller rotation.
The suction profile is meticulously designed to reduce NPSH, ensuring trouble-free operation even in the most challenging conditions.
A stainless steel shaft is crafted to endure bending-torsion loads, ensuring durability and long-lasting performance.
Featuring oversized ball bearings, the pump delivers reduced operational noise and an extended service life, highlighting its robust and reliable design.
Offers a comprehensive selection of mechanical seals or gland packings (SES), tailored to meet the specific requirements of the fluid characteristics and usage conditions, ensuring optimal adaptability and performance.

To meticulously balance axial thrust, most of our impellers are innovatively engineered with wear rings positioned both at the front and back, complemented by a strategically placed balance hole on the back shroud. In some instances where axial thrust remains minimal, the design elegantly eschews the need for a back wear ring and balance hole.
Our high-precision casting impeller is a marvel of engineering, meticulously crafted to ensure optimal performance. Available in cast iron, stainless steel, and bronze, these materials guarantee durability and longevity.
The pump cover is designed with packing that includes a soft packing seal. For enhanced sealing efficiency, the stuffing is engineered to facilitate a flow of water under certain pressure, aiding in cooling, lubrication, and cleaning.
Our state-of-the-art mechanical seals come in two varieties: single and double. Both are designed to introduce water at a specified pressure into the seal cavity, effectively rinsing the end surface to reduce friction and enhance cooling. We provide adaptable sealed cavity designs conforming to ISO3069 standards, accommodating other structures such as mechanical seals with corrugated pipes and expeller seals.
Flexible couplings
Flexible couplings, unlike their rigid counterparts, are expertly crafted to accommodate essential movements such as vibrations and thermal expansion without sustaining damage. These features make them indispensable for applications that involve unavoidable misalignment between the drive and pump shafts. Additionally, their ability to absorb vibrations significantly reduces operational noise. While the design is more complex and costly, the superior protection of shafts and bearings against damage and premature wear results in substantial maintenance savings over time.
Our commitment to quality is reflected in our use of wear-resisting disc couplings or pin couplings, ensuring enduring performance and reliability.
