Our IH end-suction pump exemplifies engineering excellence, a single-stage, single-suction (axial suction) cantilever centrifugal pump crafted to convey corrosive liquids with water-like viscosity, devoid of solid particles. It is engineered to meet the rigorous standards of ISO2858, offering a broad spectrum of performance, superior efficiency, and effortless maintenance. Compared to the F-type pump, its efficiency is approximately 5% higher, solidifying its status as an internationally acclaimed energy-saving marvel.
The IH chemical pump is adept at handling transmission medium temperatures from -20 ºC to 105 ºC. It can accommodate even higher temperatures with enhanced cooling mechanisms when needed. This versatility makes it ideal for industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fiber. It's designed to transport a variety of corrosive media that are akin to water, ensuring no contamination occurs.
Main Design Features
Engineered for high-pressure applications, this pump is compatible with flanges in PN 10 and PN 16, ensuring versatility and reliability.
Our innovative "Back pull-out" design allows seamless removal of hydraulic components without detaching the pump body from the plant pipes, streamlining maintenance and reducing downtime.
Featuring a dynamically balanced closed impeller, this pump minimizes radial loads, ensuring smooth and efficient impeller rotation for optimal performance.
Designed with a specialized suction profile, it effectively reduces NPSH, guaranteeing trouble-free operation even under the most demanding conditions.
The robust stainless steel shaft is engineered to endure bending-torsion loads, ensuring unmatched durability and operational stability.
Equipped with oversized ball bearings, this pump ensures reduced operational noise and a prolonged service life, enhancing user experience and reliability.
Offering a wide array of mechanical seals or gland packings (SES), the pump is tailored to meet the fluid characteristics and usage conditions, ensuring optimal performance and adaptability.

Our innovative pump design features a dual wear ring system, strategically placed at the front and rear of most impellers to expertly balance axial thrust. Additionally, the back shroud of the impeller hosts a precision-engineered balance hole. In instances where axial thrust is negligible, our design omits the rear wear ring and balance hole, ensuring optimal performance without unnecessary components.
The high-precision casting of our impellers guarantees exceptional performance, with material options available in robust cast iron, durable stainless steel, and luxurious bronze, tailored to meet diverse application needs.
The pump cover is thoughtfully designed with a packing system that includes a soft packing seal, which seamlessly integrates stuffing. This design allows for the introduction of pressurized water to facilitate seal cooling, enhance lubrication, and ensure thorough cleaning, promoting longevity and efficiency.
Our sophisticated sealing solutions offer both single and double mechanical seal options. These systems are equipped to introduce water under pressure into the seal cavity, effectively rinsing friction surfaces and providing superior cooling. We also accommodate ISO3069 standards, offering adaptable designs such as corrugated pipe mechanical seals and expeller seals, meeting varied and specific requirements with precision.
Flexible Couplings
Crafted for excellence, flexible couplings provide an advanced solution for absorbing movement such as vibrations and thermal expansion, without damage. Ideal for setups where drive and pump shafts are slightly misaligned, they effectively minimize operating noise. Despite the intricate and costly design, they offer remarkable maintenance savings by safeguarding shafts and bearings from damage and premature wear.
Our commitment to durability leads us to utilize wear-resistant disc couplings or pin couplings, ensuring reliability and longevity in performance.
