The IH end-suction pump is an engineering marvel, a single-stage, single-suction (axial suction) cantilever centrifugal pump ideal for handling corrosive liquids with a viscosity akin to water, free from solid particles. Adhering to ISO2858 international standards, it boasts a wide performance range, remarkable efficiency, and simplified maintenance. Compared to the F-type pump, it achieves an efficiency boost of an average of 5%, making it a celebrated energy-saving solution on the global stage.
The IH chemical pump is engineered to operate with a transmission medium temperature ranging from -20 ºC to 105 ºC. It can accommodate higher temperature mediums with advanced cooling measures if needed, making it indispensable across industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers, effortlessly transporting a variety of corrosive media similar to water, all while maintaining impeccable purity.
Main Design Features
Engineered to excel in high-pressure scenarios, it offers flange compatibility with PN 10 and PN 16, ensuring robust and reliable performance.
The innovative "Back pull-out" design allows for the seamless removal of hydraulic components without the need to detach the pump body from the plant piping, ensuring minimal disruption and maximum convenience.
Equipped with a dynamically balanced closed impeller, this pump minimizes radial loads and guarantees smooth impeller rotation, enhancing operational efficiency and longevity.
Crafted with a suction profile optimized to lower NPSH, this pump is designed for flawless, trouble-free operation even under the most demanding conditions.
Featuring a stainless steel shaft, this pump is built to endure significant bending-torsion loads, providing unmatched durability and reliability.
Incorporating oversized ball bearings, the pump ensures reduced operational noise and extends the lifespan, promising a quiet, long-lasting performance.
A diverse selection of mechanical seals or gland packings (SES) can be configured to perfectly match the fluid characteristics and usage conditions, offering tailored solutions and enhanced adaptability.

To balance axial thrust with precision, wear rings are strategically positioned at both the front and back of most impellers, complemented by a balance hole on the rear shroud. For pumps where axial thrust is minimal, the back of the impeller might not feature a wear ring or balance hole, offering design flexibility.
Our high-precision casting impellers ensure optimal performance, crafted from materials like cast iron, stainless steel, and robust bronze for reliability and durability.
The packing pump cover comes equipped with a stuffing box designed for soft packing seals. This engineering allows a controlled amount of water pressure to enter for effective seal cooling, lubrication, and cleaning, enhancing the overall efficiency and longevity of the pump operation.
Our advanced sealing systems offer options like single and double mechanical seals. These seals use water pressure within the seal cavity to rinse and cool the end surface friction, ensuring smooth operation. Furthermore, customizations according to ISO3069 standards are possible, including structures with corrugated pipes and expeller seals, catering to diverse sealing needs.
Flexible Couplings
Flexible couplings provide a solution for systems requiring accommodation of movement, such as vibrations and thermal expansion, without sustaining damage. They are perfect for scenarios with slight misalignment between drive and pump shafts. By absorbing vibrations, they significantly reduce noise levels. Although they have a more intricate and costly design, the reduction in shaft and bearing wear means long-term maintenance cost savings.
We employ wear-resisting disc couplings or pin couplings to enhance durability and performance.
