The IH end-suction pump is a brilliantly engineered, single-stage, single-suction (axial suction) cantilever centrifugal pump, skillfully designed to convey corrosive liquids with a viscosity similar to that of water, all while ensuring the absence of solid particles. Crafted according to the prestigious international standards ISO2858, it boasts an impressive wide range of performance, elevated efficiency, and unparalleled ease of maintenance. The IH pump triumphs with an average 5% efficiency boost compared to the conventional F-type pump, heralding it as a highly acclaimed energy-saving product on the global stage.
The IH chemical pump is expertly crafted to transport media at temperatures ranging from -20 ºC to 105 ºC. With optional enhanced cooling measures, it adeptly handles even higher temperatures. This versatile pump is a perfect fit for a myriad of industries, including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber sectors. It excels in transporting all variants of corrosive media analogous to water while ensuring zero contamination.
Main Design Features
Expertly engineered for high-pressure applications, this pump accommodates flanges in both PN 10 and PN 16 configurations.
The innovative "back pull-out" design allows seamless removal of hydraulic components without detaching the pump body from the plant piping systems.
A dynamically balanced closed impeller is meticulously designed to minimize radial loads, ensuring smooth and efficient impeller rotation.
The suction profile is astutely crafted to reduce NPSH, facilitating trouble-free operation even under the most demanding conditions.
Constructed with a robust stainless steel shaft, it is engineered to endure significant bending-torsion loads with resilience.
Oversized ball bearings are employed to diminish operational noise and extend the pump's service life remarkably.
Offering a large and diverse selection of mechanical seals or gland packings (SES), these components are customized to meet the exact fluid characteristics and specific conditions of use.

To expertly balance axial thrust, our innovative design features wear rings strategically placed at both the front and back of the impeller in most models. Additionally, a sophisticated balance hole is positioned on the back shroud of the impeller. For select pump models where the axial thrust is minimal, the design elegantly omits the wear ring and the balance hole at the rear of the impeller.
Our impellers, crafted with high precision through advanced casting techniques, ensure unparalleled performance. Choose from premium materials such as robust cast iron, sleek stainless steel, or classic bronze to meet your specific needs.
The pump cover is meticulously equipped with packaging designed for soft packing seals. This setup allows the introduction of pressurized water, facilitating effective seal cooling, lubrication, and cleaning, thus enhancing the overall performance and longevity of the pump.
Available in both single and double configurations, our mechanical seals are adaptable and efficient. They utilize pressurized water to enter the seal cavity, where they expertly rinse the friction surfaces and provide cooling. Depending on your requirements, the seal cavity can be customized to conform to ISO3069 standards, including options like mechanical seals with corrugated pipes and innovative expeller seals.
Durable and Adaptable Flexible Couplings
Unlike their rigid counterparts, flexible couplings offer remarkable adaptability to accommodate movements such as vibrations and thermal expansion without sustaining damage. This makes them ideal for scenarios where slight misalignment between the drive and pump shafts is unavoidable. Their ability to absorb vibrations also contributes to a reduction in operational noise. Despite their intricate and costlier design, flexible couplings provide long-term maintenance savings by safeguarding shafts and bearings from damage and premature wear.
For optimal reliability, we utilize wear-resistant disc or pin couplings, ensuring durability and efficiency in our applications.
