Introducing the IH end-suction pump—a marvel of engineering excellence. This single-stage, single-suction (axial suction) cantilever centrifugal pump is adept at conveying corrosive liquids with a viscosity akin to water, all while ensuring no solid particles are present. Meticulously crafted to meet international standards ISO2858, it boasts an impressive spectrum of performance. Renowned for its high efficiency and simplified maintenance, this pump surpasses the F-type pump by an average of 5 percent in efficiency. It stands proudly as an internationally acclaimed energy-saving product.
The IH chemical pump is designed to handle a transmission medium temperature ranging from -20 ºC to 105 ºC. With appropriate cooling measures, it can even transport media at higher temperatures. This pump is the ideal choice for industries such as chemical processing, petroleum, metallurgy, electric power, paper manufacturing, food production, pharmaceuticals, and synthetic fibers. It efficiently transports various corrosive media that are similar to water, ensuring no pollution or contamination.
Main Design Features
Engineered for excellence, this pump is suitable for high-pressure applications with its robust flanges available in PN 10 and PN 16.
The innovative 'Back pull-out' design revolutionizes maintenance by allowing the removal of hydraulic components without detaching the pump body from the plant piping.
Equipped with a dynamically balanced, closed impeller, the pump minimizes radial loads, ensuring a smooth and seamless impeller rotation.
Crafted with a specialized suction profile, this pump is designed to significantly reduce NPSH, guaranteeing trouble-free operation even under demanding conditions.
The stainless steel shaft is engineered to endure the rigors of bending-torsion loads, ensuring durability and reliability.
Employing oversized ball bearings, this pump not only reduces operational noise but also promises an extended service life.
A vast selection of mechanical seals or gland packings (SES) is available, meticulously configured to meet the specific requirements of fluid characteristics and usage conditions.

To expertly balance axial thrust, our design incorporates wear rings both at the front and rear of the impeller. Additionally, a balance hole is meticulously placed on the impeller's back shroud. However, for certain pumps where axial thrust is minimal, the sophisticated design eliminates the need for a rear wear ring and balance hole, ensuring optimal performance without unnecessary components.
Our high-precision casting impeller guarantees exceptional performance with materials including robust cast iron, quality stainless steel, and durable bronze, each crafted to perfection.
The packing pump cover, thoughtfully equipped with high-grade stuffing, caters to a soft packing seal. This intelligent design allows the stuffing to channel water under particular pressure, ensuring efficient seal cooling, lubrication, and cleaning for enhanced operation.
Our pump offers versatility with two types of mechanical seals: single and double. Both species allow water at a specific pressure to be introduced into the seal cavity, effectively rinsing the end surface to minimize friction while imparting cooling effects. Additionally, you have the flexibility to adapt to a pre-determined ISO3069 size with structures such as mechanical seals featuring corrugated pipes and innovative expeller seals, tailored to meet your precise requirements.
Durable and Flexible Couplings
In contrast to rigid couplings, flexible couplings are engineered to accommodate movement, such as vibrations and thermal expansion, without sustaining damage. This makes them perfect for scenarios with unavoidable misalignment between drive and pump shafts. Their superior ability to absorb vibrations also contributes to reducing excessive operational noise. Despite their more intricate and costly design, the long-term savings on maintenance due to the protection they offer to shafts and bearings make them a wise investment.
We offer wear-resisting disc coupling or pin coupling, each designed to ensure durability and extended lifespan.
This versatile product is ingeniously designed for a broad range of applications across various industries. It plays a critical role in urban water supply and drainage systems, central heating systems, and serves numerous sectors including iron and steel metallurgy, oil refineries, and paper mills. Whether it’s oil, power, or chemical plants, our product ensures optimal performance and reliability. Its use extends to essential infrastructure projects like airport construction and textile mills. From sugar production to mining, from consumer drainage systems to air conditioning water supplies, and from agricultural irrigation to diverse water projects, this pump is engineered to meet the demands of the most challenging environments with unparalleled efficiency.
