The IH end-suction pump is a sophisticated, single-stage, single-suction (axial suction) cantilever centrifugal pump. It's expertly crafted for conveying corrosive liquids with a viscosity akin to water, all while ensuring no solid particles are present. This pump's design, rated performance, and dimensions align with the prestigious international standards ISO2858. It boasts a remarkable suite of features such as vast operational capabilities, exceptional efficiency, and hassle-free maintenance. Compared to the traditional F-type pumps, the IH pump's efficiency is enhanced by an impressive 5 percent, making it a leader in the international arena for energy-saving solutions.
The IH chemical pump is engineered for versatility, with a transmission medium temperature range from -20 ºC to a robust 105 ºC. It can adeptly handle media at even higher temperatures with enhanced cooling measures when required. This makes it an ideal choice for industries like chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It excels in transporting an array of corrosive media similar to water, ensuring no contamination.
Main Design Features
Engineered for high-pressure scenarios, this pump is compatible with flanges in PN 10 and PN 16, catering to demanding applications.
The innovative "Back pull-out" design allows for the seamless removal of hydraulic components without the need to detach the pump body from the plant pipes, ensuring efficient maintenance.
A dynamically balanced closed impeller is incorporated to significantly minimize radial loads, ensuring a smooth and stable rotation of the impeller.
The suction profile is meticulously designed to decrease Net Positive Suction Head (NPSH), guaranteeing trouble-free operation even in the most challenging conditions.
The stainless steel shaft is crafted to endure complex bending-torsion loads, providing superior durability and reliability.
Equipped with oversized ball bearings, this pump operates with reduced noise levels while ensuring an extended service life.
Customers can choose from a wide array of mechanical seals or gland packings (SES), tailored to meet the specific demands of fluid characteristics and usage conditions.

To ingeniously balance axial thrust, our sophisticated design includes wear rings positioned both at the front and rear of most impellers. Additionally, a strategically placed balance hole resides on the back shroud of the impeller. For certain pump models where axial thrust is minimal, the design allows for an optimized structure devoid of rear wear rings and balance holes.
Our impellers boast high-precision casting which is pivotal in ensuring exceptional performance. Crafted meticulously from durable materials such as cast iron, stainless steel, and bronze, they promise robust reliability and longevity.
The packing pump cover is thoughtfully equipped with stuffing for a soft packing seal. To enhance its functionality, water under specific pressure can be directed into the stuffing for seal cooling, lubrication, and cleaning, ensuring optimal performance and longevity.
We offer both single and double mechanical seals, providing flexibility in mechanical sealing options. Water under regulated pressure passes into the seal cavity to rinse the end surface friction effectively while providing essential cooling. Our versatile solutions accommodate ISO3069 standards with designs like mechanical seals featuring corrugated pipes and expeller seals for tailored application needs.
Flexible Couplings
In contrast to rigid couplings, flexible couplings are designed to accommodate movement, such as vibrations and thermal expansion, without sustaining damage. This makes them the perfect choice for setups where a degree of misalignment is unavoidable between the drive and pump shafts. Not only do they adeptly absorb vibrations to minimize excessive operating noise, but their ingenious design also translates to long-term maintenance savings by protecting shafts and bearings, despite their more complex and costly design.
Our selection includes wear-resistant disc couplings and pin couplings, ensuring durability and efficiency in various challenging environments.
