The IH end-suction pump is a marvel of engineering, designed as a single-stage, single-suction (axial suction) cantilever centrifugal pump. It effortlessly conveys corrosive liquids with a viscosity akin to water, ensuring no solid particles interfere. This pump's mark, rated performance, and size adhere to the esteemed international standards of ISO2858. Boasting a wide range of performance, it shines with high efficiency and ease of maintenance. On average, it's a remarkable 5 percent more efficient compared to the F-type pump, earning its spot as an internationally recognized energy-saving marvel.
The IH chemical pump is versatile in its temperature handling, proficiently managing transmission medium temperatures from -20 ºC to 105 ºC. For those needing even higher temperatures, it can be equipped with enhanced cooling measures. This makes it an ideal choice across industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It excels at transporting various corrosive media that mimic water, all without causing any pollution.

To masterfully balance axial thrust, our design incorporates wear rings positioned both at the front and back of most impellers, complemented by a strategically placed balance hole on the impeller's back shroud. For pumps with minimal axial thrust, these components at the impeller's back are ingeniously omitted, ensuring performance efficiency.
Our high-precision casting impeller is the epitome of excellence, crafted to ensure optimal performance. Available in robust materials such as cast iron, stainless steel, and bronze, each impeller is designed to meet the highest standards of reliability and durability.
The pump cover, thoughtfully equipped with soft packing, serves as the ultimate shield for sealing. This packing is designed to accommodate a controlled flow of water, aiding in seal cooling, lubrication, and thorough cleaning to maintain optimal function.
With two types of mechanical seals—single and double—our innovative design allows water under controlled pressure to enter the seal cavity, effectively rinsing and cooling it. For enhanced versatility, the design can incorporate ISO3069 compliant structures, such as mechanical seals with corrugated pipes and expeller seals, to precisely meet varied requirements.
Flexible Couplings: Experience the advanced engineering of our flexible couplings, crafted to seamlessly accommodate motion and vibrations.
Our state-of-the-art flexible couplings are engineered to elegantly manage slight movements like vibrations and thermal expansions, preventing damage and maintaining alignment between drive and pump shafts. Their vibration-absorbing nature minimizes operational noise, delivering a quieter experience. While their design is sophisticated and costlier, they offer long-term maintenance savings by protecting shafts and bearings from damage and wear.
Our engineering excellence extends to the use of wear-resisting disc couplings and pin couplings, ensuring durability and reliability in every application.
