The IH end-suction pump is an outstanding single-stage, single-suction (axial suction) cantilever centrifugal pump, designed to efficiently convey corrosive liquids with viscosities akin to water, devoid of solid particles. Crafted to meet international standards ISO2858, it offers a broad spectrum of performance, exceptional efficiency, and effortless maintenance. With an efficiency boost averaging 5% over the F-type pump, it stands out as a globally recognized energy-saving marvel.
The IH chemical pump is engineered to handle transmission medium temperatures ranging from -20 ºC to 105 ºC. For higher temperature media, enhanced cooling solutions can be applied, making it ideal for use in the chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber industries. It is perfect for transporting all sorts of corrosive media that are similar to water and free from pollutants.

To ensure superior balance of axial thrust, most of our impellers boast strategically positioned wear rings at both the front and the back. These are complemented by an innovative balance hole located on the back shroud of the impeller. In certain cases where the axial thrust is minimal, the design simplifies by omitting the rear wear ring and balance hole, offering efficiency without unnecessary components.
Our high-precision casting impellers are the epitome of performance assurance, crafted from premium materials like cast iron, stainless steel, and bronze. This meticulous manufacturing ensures not only durability but also optimizes the pump's overall efficiency and reliability.
The pump cover, with its sophisticated design, incorporates high-quality stuffing for a soft packing seal. By channeling pressurized water through the stuffing, we achieve optimal seal cooling, outstanding lubrication, and effective cleaning—ensuring your pump operates seamlessly.
Our pumps come with versatile sealing options, featuring both single and double mechanical seals. By introducing pressurized water into the seal cavity, they not only rinse friction surfaces but also provide essential cooling. Additionally, the design is compatible with ISO3069 specifications, accommodating other innovative structures like corrugated pipe and expeller seal, according to your precise sealing needs.
Flexible Couplings
Flexible couplings excel in scenarios where slight movement is inevitable, such as vibrations or thermal expansion, without causing damage. Perfect for systems with unavoidable misalignment between drive and pump shafts, they efficiently dampen vibrations, lowering operational noise. While their advanced design may be complex and pricier, the long-term savings in maintenance due to shaft and bearing protection are invaluable.
Our selection includes wear-resistant disc couplings and robust pin couplings for superior performance.
