The IH end-suction pump is a marvel of engineering, offering a single-stage, single-suction (axial suction) cantilever centrifugal design. It is expertly crafted to convey corrosive liquids with a viscosity akin to water, all while ensuring no solid particles interfere with its operation. Engineered following the esteemed ISO2858 international standards, this pump boasts an impressive array of features including a broad performance range, remarkable efficiency, and effortless maintenance. Its efficiency surpasses the F-type pump by an average of 5%, establishing it as a leading energy-saving product on the global stage.
The IH chemical pump is versatile, capable of handling transmission medium temperatures ranging from -20 ºC to 105 ºC with ease. For even higher temperature mediums, enhanced cooling methods are available. This makes it an ideal choice across industries like chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers, effectively transporting a wide variety of corrosive media similar to uncontaminated water.
Main Design Features
Engineered for high-pressure applications, the pump is compatible with flanges in both PN 10 and PN 16, ensuring robustness and reliability.
The innovative 'Back pull-out' design allows for the removal of hydraulic parts without dismantling the pump body from the plant pipes, enhancing convenience and reducing downtime.
With a dynamically balanced closed impeller, the pump minimizes radial loads, ensuring smooth and efficient rotation for optimal performance.
Featuring a meticulously designed suction profile, this pump significantly reduces NPSH, ensuring seamless operation even under demanding conditions.
The stainless steel shaft is engineered to withstand substantial bending-torsion loads, providing durability and longevity.
Oversized ball bearings are employed to reduce noise levels and extend the service life of the pump, ensuring whisper-quiet, long-term operation.
A vast selection of mechanical seals or gland packings (SES) are available, tailored to meet the specific fluid characteristics and operational requirements, ensuring adaptability and precision for varied applications.

To ensure optimal performance and minimize axial thrust, our design incorporates wear rings strategically positioned both at the front and rear of most impellers. Additionally, a balance hole is thoughtfully integrated into the back shroud of the impeller. For certain models where axial thrust is minimal, the absence of a rear wear ring and balance hole is deliberate, as it is not required for efficient function.
Our high-precision casting impeller is crafted to guarantee exemplary performance. Available in robust materials such as cast iron, stainless steel, and bronze, these impellers are designed for durability and reliability.
The packing pump cover is ingeniously equipped with soft packing seals, which allow water at a certain pressure to flow through. This not only cools and lubricates the seals but also ensures they remain clean, enhancing the overall efficiency and longevity of the pump.
Our pumps offer versatility with two types of mechanical seals: single and double. Designed to accommodate a certain water pressure, these seals efficiently cleanse friction surfaces while providing a cooling effect. They are engineered to fit ISO3069 standards with customizable configurations like corrugated pipe seals and expeller seals, according to specific requirements.
Reliable Flexible Couplings
Flexible couplings provide a distinct edge over rigid couplings by accommodating movement such as vibrations and thermal expansion, without sustaining damage. They're perfect for scenarios with unavoidable misalignment between drive and pump shafts. Their ability to absorb vibrations not only reduces excessive operating noise but also enhances the longevity of shaft and bearings, offering significant maintenance savings despite a more intricate, costlier design.
We incorporate wear-resisting disc couplings or pin couplings to ensure durability and efficiency.
