The IH end-suction pump stands out as a single-stage, single-suction (axial suction) cantilever centrifugal pump, specifically crafted to convey corrosive liquids with a viscosity akin to water, all while ensuring zero solid particles. It is meticulously designed in strict accordance with international standards ISO2858, featuring a broad spectrum of performance capabilities, heightened efficiency, and user-friendly maintenance. This pump boasts an impressive enhancement in efficiency, with an average increase of 5 percent over the traditional F-type pump, firmly establishing it as a globally recognized energy-saving marvel.
The IH chemical pump is engineered to handle transmission medium temperatures ranging from -20 ºC to 105 ºC. For applications demanding higher temperatures, enhanced cooling measures can be efficiently incorporated. This pump stands as an indispensable tool across various industries, including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber sectors, adeptly transporting diverse corrosive media akin to water, without contamination.
Main Design Features
Engineered for high-pressure applications, the pump is equipped with flanges in PN 10 and PN 16, ensuring robust performance under demanding conditions.
The innovative 'Back pull-out' design allows for the seamless removal of hydraulic parts without detaching the pump body from the plant pipes, facilitating effortless maintenance.
Featuring a dynamically balanced closed impeller, this pump significantly reduces radial loads, ensuring the smooth and efficient rotation of the impeller.
The suction profile is expertly designed to minimize NPSH, guaranteeing trouble-free operation even in the most challenging conditions.
Crafted from stainless steel, the shaft is meticulously designed to endure bending-torsion loads, promising durability and resilience.
The oversized ball bearings not only diminish operational noise but also prolong the service life, promising a quieter and more enduring performance.
A vast selection of mechanical seals or gland packings (SES) is available, tailored to suit the fluid's characteristics and operational conditions, ensuring optimal performance and reliability.

To ingeniously balance axial thrust, our design features wear rings both at the front and back of the impeller for most models. A smartly placed balance hole on the back shroud further enhances this balance. In certain pump designs, where axial thrust is negligible, these components, such as the rear wear ring and balance hole, are intentionally omitted to optimize performance.
Our state-of-the-art, high-precision casting impeller guarantees superior performance. Crafted in materials like cast iron, stainless steel, and bronze, these impellers are designed to cater to diverse applications with exceptional durability and efficiency.
The meticulously engineered packing pump cover comes equipped with premium stuffing tailored for a soft packing seal. This advanced sealing system allows the passage of pressurized water to ensure optimal cooling, lubrication, and cleaning of the sealing surfaces, thereby extending the longevity of the pump.
Our product line offers both single and double mechanical seal options, each capable of handling specific pressures within the seal cavity. This configuration ensures the end surface remains clean and cool during operation, minimizing friction. Additionally, the design supports ISO3069 specifications for customized seal cavity dimensions, including innovative solutions such as corrugated pipe mechanical seals and expeller seals, ensuring adaptability to varied operational requirements.
Versatile and Durable Flexible Couplings
Flexible couplings stand out for their ability to accommodate movement, such as vibrations and thermal expansion, without sustaining damage. This flexibility makes them perfect for applications with potential misalignment between drive and pump shafts. Not only do they absorb vibrations effectively, reducing noise, but they also offer long-term maintenance savings despite their complex and costly designs, as they safeguard the shaft and bearings from damage and premature wear.
Our selection includes wear-resistant disc coupling and pin coupling, both engineered for durability and efficiency.
