The IH end-suction pump represents the pinnacle of engineering with its single-stage, single-suction (axial suction) cantilever centrifugal design. Expertly crafted to transport corrosive liquids with a viscosity akin to water, this remarkable pump excludes any solid particles, ensuring a smooth and efficient operation. It adheres to the esteemed international standards of ISO2858, showcasing a broad spectrum of performance capabilities. Boasting exceptional efficiency and effortless maintenance, the IH pump outperforms traditional F-type pumps by an average of 5%, establishing itself as a leading energy-saving innovation globally.
The IH chemical pump is engineered for versatility, handling transmission medium temperatures ranging from -20 ºC to an impressive 105 ºC. With enhanced cooling measures, it can even manage mediums at higher temperatures. This makes it ideal for a multitude of industries, including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber sectors. It excels in the transportation of various corrosive media that mirror water without causing pollution, making it an indispensable asset in industrial applications.
Main Design Features
Engineered for high-pressure applications, this pump offers flanges available in PN 10 and PN 16, making it adaptable to a variety of demanding industrial environments.
The innovative "Back pull-out" design allows for the effortless removal of hydraulic components without the need to disconnect the pump body from the plant pipes, facilitating seamless maintenance.
The closed impeller is dynamically balanced to minimize radial loads, ensuring smooth rotation and optimal performance, which enhances the pump's reliability and longevity.
The expertly designed suction profile significantly reduces NPSH (Net Positive Suction Head) requirements, enabling trouble-free operation even in challenging conditions.
Crafted from durable stainless steel, the pump's shaft is engineered to withstand bending-torsion loads, enhancing its durability and operational efficiency.
Oversized ball bearings are incorporated to significantly reduce operational noise and extend the service life of the pump, ensuring a quieter and more dependable performance.
With a vast selection of mechanical seals or gland packings (SES), the pump can be tailored to meet the specific requirements of various fluid characteristics and operating conditions, ensuring exceptional versatility and effectiveness.

To masterfully balance axial thrust, our design incorporates wear rings both at the front and rear of the majority of the impeller, with a precision-engineered balance hole on the back shroud. For pumps where axial thrust is minimal, these elements are strategically omitted, maintaining efficiency without unnecessary components.
Our high-precision casting impeller guarantees exceptional performance, available in robust materials such as cast iron, stainless steel, and bronze, catering to a wide range of demanding applications.
The packing pump cover is ingeniously equipped with stuffing designed for a soft packing seal. This mechanism allows for a certain pressure of water to pass through, facilitating seal cooling, lubrication, and cleaning with utmost efficiency.
Offering versatility, we provide both single and double mechanical seals. These configurations allow a precise pressure to permeate the seal cavity, effectively rinsing end surface friction and enhancing cooling. Our designs also adapt to ISO3069 standards, accommodating advanced structures like corrugated pipe mechanical seals and expeller seals.
Reliable and Adaptive Flexible Couplings
In contrast to rigid counterparts, flexible couplings are adept at absorbing vibrations and thermal expansions, making them perfect for scenarios with slight misalignments between drive and pump shafts. They not only reduce operating noise but also feature a more sophisticated, albeit costlier design. However, the enhanced durability they offer translates to long-term maintenance savings by protecting shafts and bearings from damage and premature wear.
Our commitment to durability is evident in our choice of resilient wear-resisting disc couplings or pin couplings.
