The IH End-Suction Pump is a highly advanced, single-stage, single-suction (axial suction) cantilever centrifugal pump designed for the efficient transportation of corrosive liquids with the viscosity akin to water, free from any solid particles. Engineered to meet the esteemed international standards ISO2858, this pump boasts an impressive array of features including a broad performance range, exceptional efficiency, and effortless maintenance. Compared to the F-type pump, it delivers an average efficiency increase of 5%, positioning it as a truly remarkable energy-saving solution that is globally recognized and promoted.
Expertly crafted for versatility, the IH Chemical Pump operates within a medium temperature range of -20 ºC to 105 ºC. For applications demanding higher temperatures, enhanced cooling solutions are available to ensure optimal functionality. This makes it an ideal choice across a diverse array of industries such as chemical, petroleum, metallurgy, electric power, paper manufacturing, food processing, pharmaceuticals, and synthetic fibers, offering reliable transportation of various corrosive media similar to water, all while ensuring zero pollution.
Main Design Features
Engineered for robustness, this pump is perfect for high-pressure applications, accommodating flanges in both PN 10 and PN 16 specifications.
The innovative 'Back Pull-Out' design facilitates the removal of hydraulic components without dismantling the pump body from the plant's piping system, thus enhancing ease of maintenance.
The dynamically balanced closed impeller is meticulously designed to minimize radial loads, ensuring smooth and efficient impeller rotation.
Featuring a meticulously designed suction profile, the pump ensures reduced NPSH (Net Positive Suction Head), guaranteeing hassle-free operation even in the most challenging conditions.
With a stainless steel shaft engineered to endure both bending and torsion loads, the pump promises unparalleled durability and reliability.
Equipped with oversized ball bearings, the pump operates with reduced noise levels and boasts an extended service life, making it a sound investment for long-term use.
Offering a vast selection of mechanical seals or gland packings (SES), the pump can be precisely configured to meet the specific requirements of the fluid's characteristics and operational conditions, ensuring maximum efficiency and adaptability.

To achieve a harmonious balance of axial thrust, our design incorporates wear rings both at the front and back of most impellers. The balance hole is strategically positioned on the back shroud of the impeller, ensuring optimal performance. In some cases, the axial thrust is minimal, eliminating the need for a rear wear ring and balance hole.
Our high-precision casting impellers are crafted to guarantee exceptional performance, available in premium materials such as cast iron, stainless steel, and bronze, meeting diverse operational needs.
The pump cover is innovatively equipped with packing, utilizing a soft packing seal. This design allows for the seamless passage of pressurized water, ensuring effective seal cooling, efficient lubrication, and thorough cleaning.
Our product range includes both single and double mechanical seals. These designs enable the introduction of pressurized water into the seal cavity, effectively rinsing and cooling the end surface. Versatile configurations are possible according to ISO3069 standards, including options like mechanical seals with corrugated pipes and expeller seals.
Durable Flexible Couplings
Flexible couplings, distinct from their rigid counterparts, adeptly manage movement such as vibrations and thermal expansion without sustaining damage. They are perfect for applications with inevitable misalignment between drive and pump shafts. Their ability to absorb vibrations significantly contributes to noise reduction. Though they feature a more intricate and costly design, they offer substantial maintenance savings by safeguarding shafts and bearings from premature damage and wear over time.
We implement either wear-resistant disc couplings or pin couplings for optimal functionality.
