Expertly crafted to handle corrosive liquids akin to water, free from solid particles, this remarkable pump aligns with the distinguished international standards of ISO2858. Revel in its expansive performance range, exceptional efficiency, and effortless maintenance. Witness a remarkable efficiency increase of approximately 5% over traditional F-type pumps, making it a globally recognized, energy-efficient powerhouse.
The IH chemical pump is engineered for versatility, with a transmission medium temperature range from -20 ºC to 105 ºC. It can accommodate higher temperatures with advanced cooling measures, making it an ideal choice for industries such as chemical manufacturing, petroleum, metallurgy, electric power, paper production, food processing, pharmaceuticals, and synthetic fibers. Seamlessly transport various corrosive media akin to water without compromising quality or causing pollution.
Main Design Features
Engineered for excellence in high-pressure applications, the pump comes with robust flanges in PN 10 and PN 16, ensuring optimal performance and reliability.
With a revolutionary 'Back pull-out' design, maintenance becomes a breeze as hydraulic components can be effortlessly removed without disengaging the pump body from the plant pipelines.
Experience the precision of a dynamically balanced closed impeller, meticulously crafted to minimize radial loads and guarantee the smoothest rotation of the impeller.
Our suction profile is expertly designed to reduce NPSH, ensuring seamless operation even under the most demanding conditions.
The stainless steel shaft is a testament to durability, engineered to withstand the rigors of bending-torsion loads, ensuring long-lasting performance.
Oversized ball bearings are incorporated to provide whisper-quiet operation and significantly extend the service life of the pump.
A vast selection of mechanical seals or gland packings (SES) is available, meticulously configured to meet the specific requirements of fluid characteristics and application conditions, offering unparalleled customization.

In a strategic endeavor to balance axial thrust, our pumps feature wear rings positioned both at the forefront and rear of the majority of the impeller, complemented by a balance hole meticulously designed into the back shroud of the impeller. This intricate design ensures optimal performance. For certain pumps where the axial thrust is minimal, the innovative design allows for the exclusion of wear rings and balance holes at the back of the impeller, maintaining efficiency without unnecessary components.
Our high-precision casting impeller is a testament to superior performance and quality, crafted meticulously from premium materials such as cast iron, stainless steel, and bronze, ensuring reliability and durability in every application.
The packing pump cover is expertly equipped with stuffing for a soft packing seal, which ingeniously allows the passage of water under a certain pressure for effective seal cooling, lubrication, and cleaning, ensuring seamless operation and longevity.
Our pumps offer a versatile choice between single and double mechanical seals, each designed to accommodate specific needs. Water is introduced at a controlled pressure into the seal cavity, effectively rinsing the end surface friction while providing a cooling effect. Our seals are engineered to be adaptable, capable of conforming to the ISO3069 standard or accommodating other advanced structures, including mechanical seals with corrugated pipes and expeller seals, according to specific requirements.
Flexible Couplings
Unlike their rigid counterparts, flexible couplings are engineered to accommodate certain movements, such as vibrations and thermal expansion, without sustaining damage. This makes them particularly ideal for applications where an unavoidable misalignment exists between the drive and pump shafts. Their impressive ability to absorb vibrations not only reduces excessive operational noise but also extends the lifespan of the components they protect. Though they embody a more intricate and costly design, the investment is justified through significant maintenance savings over time, as they preserve the integrity of shafts and bearings, preventing damage and premature wear.
Our exemplary use of wear-resisting disc couplings and pin couplings underscores our commitment to durability and performance excellence.
