The IH end-suction pump is a marvel of engineering, featuring a single-stage single-suction (axial suction) cantilever centrifugal design. It is adept at transporting corrosive liquids with a viscosity akin to water, yet without solid particles. This pump embodies the gold standard as it adheres to the international norms ISO2858, boasting a vast range of performance capabilities, exceptional efficiency, and ease of maintenance. Notably, its efficiency is on average 5% higher than the traditional F-type pump, marking it as a flagship in the international energy-saving product lineup.
The IH chemical pump excels in handling transmission medium temperatures ranging from -20 ºC to 105 ºC. With enhanced cooling measures, it can even manage higher temperatures, making it perfect for diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. Its prowess lies in transporting various corrosive media similar to water, all without pollution.
Main Design Features
Engineered for high-pressure scenarios, this pump is equipped with robust flanges compliant with PN 10 and PN 16 standards.
The innovative "Back pull-out" design allows for the effortless removal of hydraulic parts, ensuring the pump body remains intact with the plant pipes, simplifying maintenance significantly.
The closed impeller is dynamically balanced to reduce radial loads, ensuring the impeller rotates smoothly and efficiently.
Crafted with a refined suction profile, this pump is designed to lower NPSH requirements, enabling seamless operation even in challenging conditions.
The stainless steel shaft is meticulously engineered to endure bending-torsion loads, offering unmatched durability and reliability.
Oversized ball bearings are integrated to diminish working noise and extend the service life of the pump, ensuring a quieter and longer-lasting operation.
A vast array of mechanical seals or gland packings (SES) are available, meticulously configured to match the fluid characteristics and usage conditions, delivering tailored sealing solutions.

To expertly manage and balance axial thrust, our pumps are ingeniously designed with wear rings strategically placed at both the front and rear of most impellers. The meticulously engineered balance hole is located on the back shroud of the impeller to optimize performance. However, for certain pumps where the axial thrust is minimal, the sophisticated design negates the need for rear wear rings and balance holes.
Our high-precision casting impeller ensures impeccable performance and is available in robust materials such as cast iron, stainless steel, and bronze, guaranteeing durability and reliability.
The packing pump cover is thoughtfully equipped with stuffing designed for a soft packing seal. This advanced stuffing system allows water to be introduced under specific pressure conditions to facilitate cooling, provide lubrication, and ensure thorough cleaning of the seal.
Our product offers versatility with both single and double mechanical seal options. These seals allow water to be introduced under a specific pressure into the seal cavity, effectively rinsing and cooling the end surface, reducing friction. Tailored to meet ISO3069 standards, the design can accommodate other structures, such as a mechanical seal with corrugated pipe and an expeller seal, ensuring adaptability and optimal performance.
Flexible Couplings
Unlike rigid couplings, our advanced flexible couplings are engineered to manage movement such as vibrations and thermal expansion without sustaining damage. They are ideal for scenarios involving unavoidable misalignment between the drive and pump shafts. By proficiently absorbing vibrations, these couplings minimize excessive noise, providing a quieter operation. While the design is more complex and costly, the long-term benefits in maintenance savings are significant, as they protect shafts and bearings from damage and wear.
We employ wear-resistant disc couplings or pin couplings to ensure superior performance and longevity.
