The IH end-suction pump is a marvel of engineering, featuring a single-stage single-suction (axial suction) cantilever centrifugal design, perfectly crafted to transport corrosive liquids that mirror the viscosity of water, devoid of solid particles. Its mark, rated performance, and dimensional metrics align with the esteemed international standards ISO2858. This translates into a pump that offers an expansive range of capabilities, superior efficiency, and ease of maintenance. Noteworthy is its average efficiency boost of 5 percent over the traditional F-type pump, positioning it as a leading energy-saving product on the global stage.
This IH chemical pump can adeptly handle transmission medium temperatures ranging from -20 ºC to 105 ºC. It's engineered to manage even higher temperatures with enhanced cooling solutions if required, making it an ideal choice for industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber. It is particularly suited for transporting various corrosive media that resemble water in characteristics, ensuring an environmentally friendly operation.

To expertly balance axial thrust in our pumps, we incorporate strategically placed wear rings both at the front and rear of most impellers. Additionally, the back shroud of the impeller features a precision-engineered balance hole. However, in cases where the axial thrust is minimal, the rear wear ring and balance hole can be omitted, optimizing efficiency without compromising performance.
Our impellers boast high-precision casting techniques to ensure exemplary performance. Available in durable materials such as cast iron, stainless steel, and bronze, these impellers are crafted to meet your toughest demands and provide long-lasting, reliable service.
The packing pump cover is innovatively designed with a stuffing feature for a soft packing seal. This design allows a certain pressure of water to flow through, thereby facilitating effective seal cooling, lubrication, and cleaning for optimal operation.
Our advanced seal options include both single and double mechanical seals, engineered for superior performance. Water is introduced under a specific pressure into the seal cavity, which effectively rinses the end surface friction while providing necessary cooling. Moreover, our designs accommodate ISO3069 specifications, allowing for diverse adaptations including mechanical seals with a corrugated pipe or expeller seals, tailored to your exact needs.
Flexible couplings
In contrast to their rigid counterparts, flexible couplings are adept at managing slight movements, such as vibrations and thermal expansions, without sustaining damage. This makes them an ideal choice for applications where minor misalignments between the drive and pump shafts are unavoidable. They excel at absorbing vibrations, thereby diminishing excessive operational noise. Although their design is more intricate and costly, the long-term maintenance savings are significant, as they protect shafts and bearings from premature wear and damage.
We employ wear-resisting disc couplings or pin couplings, chosen for their exceptional durability and performance.
