The IH end-suction pump stands as a pinnacle of engineering excellence, offering a single-stage, single-suction (axial suction), cantilever centrifugal design. This innovative pump is crafted to handle corrosive liquids with viscosities akin to water, all while deftly avoiding solid particles. Adhering to the esteemed international standards ISO2858, this pump boasts a broad spectrum of performance capabilities. It combines high efficiency with effortless maintenance, achieving an impressive average efficiency increase of 5% compared to the traditional F-type pump. As a leading energy-saving solution on the global stage, our product sets new benchmarks in performance.
The IH chemical pump is engineered for versatility, capable of handling transmission medium temperatures ranging from -20 ºC to 105 ºC. With advanced cooling measures, it can manage even higher temperatures, making it ideal for a diverse array of industries including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fiber. Our pump excels at transporting a multitude of corrosive media with water-like characteristics while ensuring minimal pollution-a testament to its superior design and functionality.
Main Design Features
Expertly crafted for high-pressure scenarios, our pump is compatible with PN 10 and PN 16 flange systems, ensuring robust and reliable functionality in demanding environments.
Our ingenious 'Back pull-out' design revolutionizes maintenance by allowing seamless removal of hydraulic components without detaching the pump body from the plant's piping infrastructure.
Featuring a dynamically balanced closed impeller, our pump minimizes radial loads, guaranteeing smooth and efficient impeller rotation, thus optimizing the pump's longevity and reliability.
The precision-engineered suction profile is tailored to reduce NPSH, ensuring uninterrupted and trouble-free operation, even in the most challenging and demanding conditions.
Constructed from premium stainless steel, our shafts are designed to endure significant bending-torsion loads, providing unparalleled durability and performance.
Equipped with oversized ball bearings, our pump significantly reduces operational noise while extending its service life, delivering a quiet, cost-effective, and long-lasting solution.
Our extensive array of mechanical seals or gland packings (SES) is thoughtfully configured to meet the unique requirements of varied fluid characteristics and operational conditions, offering unmatched versatility and protection.

To expertly balance axial thrust, our design incorporates wear rings strategically placed both in front and at the rear of most impellers, complemented by a balance hole on the impeller's back shroud. In certain models where the axial thrust is minimal, we thoughtfully exclude the rear wear ring and balance hole, ensuring efficiency and precision.
Our impellers, crafted with high-precision casting, guarantee exceptional performance and durability. Available in robust materials such as cast iron, stainless steel, and bronze, these impellers are engineered to meet the highest standards of quality and reliability.
The packing pump cover is ingeniously designed with soft packing seals and stuffing, allowing for the infusion of water at controlled pressure. This not only ensures effective seal cooling but also provides lubrication and cleaning, enhancing the pump's operational efficiency.
Offering versatility, we provide both single and double mechanical seal options. Water, introduced at a specific pressure into the seal cavity, diligently cleanses and cools the end surface friction. Designed in accordance with ISO3069 standards, these seals can be complemented by advanced structures like corrugated pipe and expeller seal, adapting effortlessly to your needs.
Flexible couplings
Flexible couplings stand out for their ability to handle movement such as vibrations and thermal expansion, protecting the system from misalignments between the drive and pump shafts. By absorbing vibrations, they not only reduce noise but also contribute to a quieter operation. Although they involve a more intricate and costly design, the long-term benefits include significant maintenance savings, as they safeguard the shaft and bearings from damage and premature wear.
We utilize wear-resistant disc couplings or pin couplings to ensure durability and optimal performance, enhancing the overall resilience and longevity of our pumps.
