The IH End-Suction Pump is a marvel of engineering, combining the elegance of single-stage, single-suction (axial suction) cantilever centrifugal design to effectively handle corrosive liquids. Ideal for fluids with viscosities similar to water and free of solid particles, this pump adheres to international ISO2858 standards. It dazzles with its wide performance range, unmatched efficiency, and effortless maintenance. Compared to the F-type pump, it boasts an impressive 5% increase in efficiency, positioning itself as a globally recognized energy-saving product.
Engineered for resilience, the IH Chemical Pump handles transmission medium temperatures ranging from -20 ºC to 105 ºC, and can accommodate even higher temperatures with enhanced cooling measures if needed. It is an indispensable tool across diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It is perfect for transporting various corrosive media akin to water, all while ensuring zero pollution.
Main Design Features
Expertly designed for high-pressure applications, the IH Pump comes equipped with robust flanges available in PN 10 and PN 16.
Our innovative “Back Pull-Out” design revolutionizes maintenance, allowing you to effortlessly remove hydraulic components without disturbing the pump body from its existing pipeline configuration.
With a dynamically balanced closed impeller, this pump minimizes radial loads, ensuring a seamless, smooth rotation and heightened operational efficiency.
The meticulously designed suction profile is engineered to lower NPSH, guaranteeing trouble-free functionality even in the most demanding environments.
Crafted from high-quality stainless steel, the shaft is designed to endure both bending and torsion loads, offering unparalleled durability.
Our oversized ball bearings are designed to significantly reduce operational noise, extending the service life of the pump to new heights.
With a vast array of mechanical seals and gland packings (SES) tailored to the specific requirements of fluid characteristics and application conditions, you can trust this pump to meet all your needs with precision.

To expertly balance axial thrust, our design incorporates wear rings both at the front and back of most impellers, complemented by a strategically placed balance hole on the impeller's back shroud. In certain models where the axial thrust is minimal, we optimize efficiency by omitting the rear wear ring and balance hole, ensuring peak performance without excess components.
Our high-precision casting impeller guarantees exceptional performance, crafted meticulously from premium materials such as cast iron, stainless steel, and bronze, offering durability and reliability.
The packing pump cover is ingeniously fitted with stuffing for a soft packing seal, allowing pressurized water to flow through, serving the dual purpose of cooling and lubrication while efficiently cleaning the seal.
We offer two variants of mechanical seals: single and double. These are designed to allow pressurized water into the seal cavity, effectively rinsing and cooling the friction surfaces. For tailored solutions, we accommodate the use of ISO3069-compatible structures, including options like mechanical seals with corrugated pipes and expeller seals.
Flexible Couplings
Distinct from rigid couplings, our flexible couplings adeptly handle movement such as vibrations and thermal expansions without damage, making them perfect for scenarios with inevitable misalignment between drive and pump shafts. Their vibration-absorbing capabilities contribute to reducing operational noise. While the design may be more intricate and costly, the long-term maintenance savings due to enhanced protection of shafts and bearings from damage and wear are substantial.
We employ durable wear-resisting disc couplings or pin couplings for superior performance.
