The IH end-suction pump represents a remarkable evolution in pump technology. As a single-stage, single-suction (axial suction) cantilever centrifugal pump, it is masterfully engineered to handle corrosive liquids possessing a viscosity akin to water, devoid of solid particles. Crafted with precision, this pump adheres to the prestigious international standards ISO2858, showcasing an array of impressive attributes: a vast spectrum of performance capabilities, superior efficiency, and effortless maintenance. Remarkably, the IH pump's efficiency outshines the F-type pump by an average of 5 percent, making it a globally recognized leader in energy-saving technology.
Capable of transporting media at temperatures ranging from -20 ºC to 105 ºC, the IH chemical pump is engineered to manage even higher temperatures with advanced cooling solutions when needed. It is the ideal choice for diverse industries, including chemical, petroleum, metallurgy, electric power, paper production, food processing, pharmaceuticals, and synthetic fibers, adept at conveying a multitude of corrosive media that share water's non-pollutant characteristics.
Main Design Features
Engineered for demanding high-pressure applications, this pump is equipped with flanges that comply with PN 10 and PN 16 standards, ensuring robust performance under pressure.
The innovative 'Back pull-out' design allows for convenient maintenance, enabling the removal of hydraulic components without disassembling the pump body from the operational piping system.
A dynamically balanced closed impeller ensures minimal radial loads, promoting seamless rotation and enhanced operational stability.
Optimized suction profile ingeniously designed to minimize NPSH, ensuring reliable performance even in challenging conditions.
Constructed from resilient stainless steel, the shaft is meticulously designed to endure bending and torsion loads, promising durability and strength.
Oversized ball bearings are integrated to diminish operational noise and extend the service life, guaranteeing a quieter and more reliable pump experience.
A diverse selection of mechanical seals or gland packings (SES) is available, carefully configured to align with the distinct characteristics of the fluid and its usage conditions, providing optimal protection and efficiency.

To impeccably balance axial thrust, our design ingeniously incorporates wear rings both at the front and rear of most impellers, complemented by a balance hole strategically situated on the back shroud. However, for pumps where axial thrust is minimized, these components are not necessary, ensuring a streamlined design without the need for a rear wear ring or balance hole.
Our high-precision casting impeller ensures impeccable performance. Crafted from premium materials such as cast iron, stainless steel, and bronze, these impellers provide reliability and durability.
The packing pump cover is meticulously equipped with stuffing for a soft packing seal. This design allows the stuffing to access a controlled pressure of water, facilitating seal cooling, lubrication, and cleaning for optimal functionality.
Our advanced design offers two prominent mechanical seal types: single and double mechanical seals. These systems allow pressurized water to flow into the seal cavity, effectively rinsing the end surface friction while providing a cooling effect. Flexibility in design permits adaptation to the ISO3069 standard, including configurations like mechanical seals with corrugated pipes and expeller seals, catering to diverse demands.
Flexible couplings
Flexible couplings, unlike their rigid counterparts, are designed to endure movements such as vibrations and thermal expansions without sustaining damage. This makes them the perfect choice for applications where a slight misalignment between the drive and pump shafts is unavoidable. Additionally, their ability to absorb vibrations significantly reduces excessive operating noise. While they require a more complex and costly design, the long-term benefits include substantial maintenance savings as they safeguard shafts and bearings from damage and early wear.
We proudly utilize wear-resistant disc couplings or pin couplings to ensure enduring performance and reliability.
