Introducing the IH end-suction pump, a marvel of single-stage, single-suction (axial suction) cantilever centrifugal pump technology. This exceptional pump is designed to convey corrosive liquids with a viscosity akin to water, and does so without any solid particles. Conforming to the esteemed international standards ISO2858, this pump stands out with its remarkable attributes: a broad performance range, unmatched efficiency, and simplified maintenance. Compared to the F-type pump, it boasts an average efficiency increase of 5 percent, positioning it as a globally endorsed, energy-saving powerhouse.
The IH chemical pump excels in handling transmission medium temperatures ranging from -20 ºC to 105 ºC, and can adeptly manage higher temperatures with enhanced cooling measures when required. This pump is indispensable in industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It transports a variety of corrosive media, akin to water, efficiently and without contamination.
Main Design Features
Engineered for high-pressure applications, this pump is equipped with robust flanges available in PN 10 and PN 16, ensuring versatile adaptability.
The revolutionary 'Back pull-out' design allows for seamless removal of hydraulic components without dismantling the pump body from plant pipes, streamlining maintenance.
Featuring a dynamically balanced closed impeller, this design minimizes radial loads, ensuring a flawlessly smooth rotation of the impeller for optimal performance.
The suction profile is meticulously crafted to lower NPSH, guaranteeing trouble-free operation even in the most demanding conditions.
The stainless steel shaft is expertly engineered to endure bending-torsion loads, delivering unwavering strength and reliability.
Equipped with oversized ball bearings, this pump ensures reduced operational noise and extends its service life significantly, promising durability.
Offering an extensive selection of mechanical seals or gland packings (SES), these are configured precisely according to the fluid's characteristics and operational conditions, enhancing adaptability and performance.

To ingeniously balance axial thrust, our design incorporates wear rings both at the front and rear of most impellers, complemented by a balance hole on the impeller's back shroud. For pumps with minimal axial thrust, we ingeniously eliminate the need for a rear wear ring and balance hole, optimizing efficiency.
Crafted with precision, our high-precision casting impellers redefine performance. Choose from premium materials such as cast iron, stainless steel, and bronze, tailored to meet your specific needs.
Our pump cover is meticulously equipped with packing for a soft packing seal. The intelligent design allows stuffing to channel a controlled pressure of water for effective seal cooling, lubrication, and cleaning, ensuring seamless operations.
Explore versatility with our single and dual mechanical seal options. These seals efficiently channel a specific water pressure into the cavity, providing impeccable surface friction rinse and cooling effects. Adapt to your requirements with ISO3069 compliant structures, including corrugated pipe mechanical seals and expeller seals.
Flexible Couplings
Experience the innovation of flexible couplings. Unlike rigid variants, these couplings gracefully accommodate movements such as vibrations and thermal expansion, preventing damage. Perfect for applications with unavoidable misalignment, they excel in vibration absorption, significantly reducing operational noise. While their design is complex and costlier, the protection they offer to shafts and bearings from damage and early wear ensures substantial long-term maintenance savings.
We incorporate wear-resisting disc couplings or pin couplings, exemplifying durability and reliability.
