The IH end-suction pump, a marvel of engineering, is a single-stage, single-suction (axial suction) cantilever centrifugal pump. It is designed to transport corrosive liquids with water-like viscosity, devoid of solid particles. It adheres to international standards ISO2858 for performance and sizing, making it a pinnacle of global energy efficiency. With a remarkable efficiency boost of approximately 5 percent over the F-type pump, it stands as a leader in the international arena for energy-saving solutions, offering an extensive performance range, exceptional efficiency, and effortless maintenance.
The IH chemical pump boasts a wide operational temperature range from -20 ºC to 105 ºC and can handle higher temperatures with enhanced cooling measures if needed. It is ideally suited for diverse industries including chemical processing, petroleum refinement, metallurgy, electric power generation, paper production, food processing, pharmaceuticals, and synthetic fibers. This versatile pump is designed to transport all types of corrosive media, maintaining water-like purity without contamination.
Main Design Features
Engineered for high-pressure applications, this pump is equipped with robust flanges suitable for PN 10 and PN 16 ratings.
The innovative "Back pull-out" design allows for easy maintenance by enabling the removal of hydraulic parts without dismantling the entire pump body from the plant's piping system.
Featuring a dynamically balanced closed impeller, this pump minimizes radial loads, ensuring smooth and seamless impeller rotation.
Its suction profile is meticulously crafted to lower NPSH, ensuring reliable, trouble-free operation even in the most demanding conditions.
Built with a robust stainless steel shaft, this pump is designed to endure significant bending and torsional loads, promising durability.
The pump's oversized ball bearings are engineered to significantly reduce operational noise and provide an extended service lifespan.
A diverse selection of mechanical seals or gland packings (SES) is available, tailored to meet the specific requirements dictated by fluid characteristics and usage conditions.

To masterfully balance axial thrust, our design includes wear rings strategically positioned at both the front and rear of the majority of the impeller. Additionally, a precision-engineered balance hole is situated on the impeller's back shroud. However, for pumps where axial thrust is minimal, the design is streamlined—eliminating the need for rear wear rings and balance holes.
Our high-precision casting impeller guarantees superior performance, crafted from robust materials such as cast iron, stainless steel, and bronze to meet diverse industrial demands.
The packing pump cover is innovatively equipped with specialized stuffing for a soft packing seal. This design permits the passage of water under certain pressure for essential seal cooling, lubrication, and cleaning, ensuring optimal performance and longevity.
The pump offers versatility with both single and double mechanical seal options. Water under specific pressure enters the seal cavity, efficiently rinsing and cooling the end surface friction. For enhanced adaptability, the design accommodates ISO3069 prescribed structures, such as those using corrugated pipe seals and expeller seals.
Advanced Flexible Couplings
Flexible couplings stand out by accommodating movement, such as vibrations and thermal expansion, without sustaining damage, making them ideal for applications with unavoidable misalignment between drive and pump shafts. Their ability to absorb vibrations effectively reduces excessive operating noise. While they feature a more intricate and costly design, the protection they offer against shaft and bearing damage translates to substantial maintenance savings over time.
Utilizing wear-resistant disc coupling or pin coupling, we ensure durability and exceptional performance.
