Introducing the IH end-suction pump, a marvel in modern engineering. This single-stage, single-suction (axial suction) cantilever centrifugal pump is designed to convey corrosive liquids with water-like viscosity, ensuring no solid particles are present. Built to meet the renowned international standards of ISO2858, it boasts an expansive range of performance features, high efficiency, and effortless maintenance. Uniquely, its efficiency surpasses the F-type pump by an impressive average of 5 percent, positioning it as a globally recognized energy-saving solution.
Our IH chemical pump is adept at handling transmission medium temperatures ranging from -20 ºC to 105 ºC. Should you require higher temperature transport, our enhanced cooling measures ensure seamless operation. This pump finds its ideal application across diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers, effortlessly transporting an array of corrosive media akin to water, all without causing pollution.
Main Design Features
Engineered to excel in high-pressure applications, these pumps are available with flanges in both PN 10 and PN 16 options.
Equipped with a 'Back pull-out' design, it allows for easy removal of hydraulic components without necessitating the disassembly of the pump body from plant piping.
The dynamically balanced closed impeller is crafted to minimize radial loads, ensuring the impeller rotates smoothly and efficiently.
A meticulously designed suction profile significantly reduces NPSH, guaranteeing trouble-free operation even in the most demanding conditions.
Constructed with a robust stainless steel shaft, it is engineered to resist the rigorous bending and torsion loads.
Oversized ball bearings are incorporated to ensure reduced operational noise and extend the pump's service life significantly.
We offer a broad selection of mechanical seals or gland packings (SES), each configured to meet the specific requirements of the fluid's characteristics and operational conditions.

To masterfully balance axial thrust, our design ingeniously incorporates wear rings on both the front and back of most impellers, while a balance hole graces the back shroud of the impeller. For pumps where axial thrust is minimal, these components are thoughtfully omitted, streamlining the design without compromising functionality.
Our high-precision casting impellers are meticulously crafted to ensure unparalleled performance. Available in robust materials such as cast iron, sleek stainless steel, and enduring bronze, they stand as a testament to quality and durability.
The packing pump cover comes equipped with expertly installed stuffing for a soft packing seal. This advanced design allows for a controlled flow of water into the stuffing to maintain optimal seal cooling, lubrication, and cleaning, ensuring seamless operation.
Our mechanical seals come in two sophisticated varieties: single and double. These seals utilize water at a precise pressure to enter the seal cavity, providing essential rinsing and cooling to the end surface friction. Adaptable to form ISO3069 structures, they can incorporate corrugated pipe seals and expeller seals to meet varied demands.
Flexible Couplings
Flexible couplings, distinct from their rigid counterparts, excel in accommodating movements like vibrations and thermal expansion without incurring damage. They are the ideal choice for scenarios with inevitable misalignment between drive and pump shafts, adeptly absorbing vibrations to minimize operating noise. While their intricate design may incur higher costs, the long-term maintenance savings, thanks to their ability to safeguard shafts and bearings from damage and wear, make them a worthwhile investment.
We utilize advanced wear-resisting disc couplings and robust pin couplings for superior performance.
