The IH end-suction pump is a marvel of engineering, boasting a single-stage single-suction (axial suction) cantilever centrifugal design. It is meticulously crafted to convey corrosive liquids with a viscosity akin to water, free of solid particles. With its design marking, rated performance, and sizing aligned with international standards ISO2858, this pump stands out for its expansive performance range, extraordinary efficiency, and simplicity of maintenance. It outperforms the competition, with an average efficiency increase of 5% compared to the traditional F-type pump, establishing itself as a beacon in the global movement toward energy-saving solutions.
The IH chemical pump is designed for versatility, operating efficiently at a medium temperature range from -20 ºC to 105 ºC. For mediums with a higher temperature, enhanced cooling measures ensure optimal performance. This makes it an ideal choice across diverse industries including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber sectors. Whether transporting corrosive media or ensuring clean operations, this pump delivers unparalleled efficiency and reliability in handling water-like, non-polluting fluids.
Main Design Features
Engineered for high-pressure scenarios, it comes equipped with robust flanges in PN 10 and PN 16, ensuring adaptability and resilience in demanding applications.
The innovative "Back pull-out" design feature allows for seamless removal of hydraulic components without the need to detach the pump body from the plant pipes, ensuring minimal downtime and maximum convenience.
Its dynamically balanced closed impeller is specifically designed to minimize radial loads, providing smooth, uninterrupted rotation and heightened operational efficiency.
With a suction profile meticulously designed to lower NPSH, it guarantees trouble-free operation even in the most challenging conditions.
The stainless steel shaft is engineered to endure bending and torsion loads, promising durability and robust performance under pressure.
Oversized ball bearings are incorporated to significantly reduce working noise and extend the service life of the pump, ensuring a quiet and long-lasting operation.
A wide array of mechanical seals or gland packings (SES) is available, customized to meet the specific requirements of fluid characteristics and usage conditions, ensuring optimal adaptability and performance.

To masterfully counterbalance axial thrust, our design includes precise wear rings positioned both at the front and rear of most impellers, complemented by a strategically placed balance hole on the impeller's back shroud. For pumps where axial thrust is minimal, these components are omitted, ensuring optimized functionality without unnecessary parts.
Our high-precision casting impeller is a testament to superior performance and durability, available in a selection of robust materials such as cast iron, stainless steel, and elegant bronze, catering to a variety of needs and environments.
The packing pump cover is adeptly equipped with well-engineered stuffing for a soft packing seal. It ingeniously allows water to pass through at a certain pressure, ensuring efficient seal cooling, lubrication, and cleaning, maintaining the pump's optimal operation.
Our advanced seal solutions include single and double mechanical seal options. Water is guided into the seal cavity under controlled pressure, serving to cleanse the end surface friction and deliver a cooling effect. For versatility, we offer customization to meet ISO3069 standards, including options like corrugated pipe mechanical seals and expeller seals, perfectly tailored to your specific requirements.
Flexible Couplings
Flexible couplings stand out by allowing a certain degree of movement such as vibrations and thermal expansion without sustaining damage, making them indispensable for cases of unavoidable misalignment between drive and pump shafts. Their ability to absorb vibrations greatly reduces operational noise, offering a quieter experience. Although they entail a more complex and costly design, the long-term benefits include significant maintenance savings as they prevent damage and premature wear to shafts and bearings.
Our preference is for wear-resistant disc coupling or pin coupling, ensuring unmatched durability and reliability in demanding scenarios.
