Introducing the IH end-suction pump, a marvel of engineering in single-stage, single-suction (axial suction) cantilever centrifugal pumps. Expertly designed to handle corrosive liquids with a viscosity akin to water, devoid of solid particles, it adheres to the highest international standards, ISO2858. Embrace a world of exceptional performance, unmatched efficiency, and effortless maintenance. The IH pump boasts an average of 5% higher efficiency compared to the F-type pump, making it a leading choice for energy conservation on a global scale.
The IH chemical pump is a versatile powerhouse, working within a temperature range of -20 ºC to 105 ºC. For higher temperature media, enhanced cooling measures can be employed, making it ideal for industries like chemical, petroleum, metallurgy, and more. Whether for electric power, paper, food, pharmaceutical, or synthetic fiber production, it efficiently transports all sorts of corrosive media that are water-like and pollution-free.

To masterfully balance the axial thrust in our pumps, a sophisticated design integrates wear rings strategically placed both at the front and back of most impellers. A precision-engineered balance hole is expertly crafted on the back shroud of the impeller. In some models, where the axial thrust is inherently minimal, the design omits a rear wear ring and balance hole, signifying a streamlined approach for specific applications.
Our high-precision cast impellers are the hallmark of performance excellence, offered in cast iron, stainless steel, and bronze. This precision casting ensures that every pump delivers optimal performance and reliability, meeting the stringent demands of diverse industrial applications.
The pump's packing cover is meticulously equipped with stuffing, catering to the soft packing seal mechanism. This design allows the stuffing to channel specific water pressure for sealing, cooling, lubrication, and cleaning purposes, ensuring the pump operates efficiently and extends its operational lifespan.
We offer dual options for mechanical seals: the single mechanical seal and the double mechanical seal, each tailored for specific needs. Sealing efficiency is enhanced as water is introduced into the seal cavity under predetermined pressure, ensuring the end surfaces are rinsed and cooled effectively. For more specialized requirements, our adaptable design accommodates ISO3069-compatible structures, including mechanical seals with corrugated pipes and expeller seals.
Flexible Couplings
Flexible couplings are a marvel of engineering, designed to accommodate movement, such as vibrations and thermal expansion, without sustaining damage. Ideal for settings with unavoidable misalignment between drive and pump shafts, they absorb vibrations efficiently, mitigating excessive noise. Although they feature a more intricate and costly design, the long-term benefits include substantial maintenance savings, as they protect shafts and bearings from damage and premature wear.
For enhanced durability, we employ wear-resistant disc coupling or pin coupling, ensuring long-lasting performance and reliability in demanding environments.
This highly versatile product is expertly engineered for an array of crucial applications. It plays an indispensable role in urban water supply and drainage, seamlessly underpinning municipal water infrastructures and central heating systems. Esteemed sectors such as iron and steel metallurgy, oil refineries, and paper mills rely on its robust performance. Its functionality extends to pivotal industries like power plants, airport construction, and chemical plants, while it also supports textile mills and sugar manufacturing. Furthermore, this pump is vital in consumer drainage systems of plant mines, ensuring the efficient operation of air conditioning water supply systems, agricultural irrigation, and an extensive range of water-related projects.
