The IH end-suction pump is a marvel of engineering, designed as a single-stage, single-suction (axial suction) cantilever centrifugal masterpiece. It excels in transporting corrosive liquids with viscosities akin to water and without any solid particulates. Conforming to the esteemed international standards ISO2858, it offers an expansive range of performance, unmatched efficiency, and effortless maintenance. Remarkably, its efficiency surpasses the F-type pump by an average of 5%, positioning it as a frontrunner in the global movement for energy-efficient solutions.
Expertly crafted for versatility, the IH chemical pump operates within a medium temperature range of -20 ºC to 105 ºC. With enhanced cooling options available, it can easily handle even higher temperature media. This adaptability makes it ideal for diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It reliably transports a variety of corrosive media that are water-like yet pollution-free.

To masterfully balance axial thrust, our design incorporates sophisticated wear rings both at the forefront and rear of most impellers, complemented by a strategically positioned balance hole on the back shroud. For certain pumps with less significant axial thrust, our innovation eliminates the need for rear wear rings and balance holes, enhancing efficiency.
Our high-precision casting impeller is engineered with excellence to ensure top-tier performance, available in robust materials such as cast iron, sleek stainless steel, and durable bronze.
The pump cover for our packing pump is expertly fitted with stuffing, facilitating a soft packing seal. This meticulously designed stuffing allows for the introduction of water under a certain pressure, ensuring effective seal cooling, optimal lubrication, and thorough cleaning, enhancing the longevity and reliability of the pump.
Our mechanical seal options include a single mechanical seal and a double mechanical seal. These advanced seals allow water under controlled pressure to enter the seal cavity, effectively rinsing the end surface friction while providing a cooling effect. According to specific needs, the sealed cavity can be adapted to meet ISO3069 predetermined size standards with alternative structures, such as mechanical seals with corrugated pipes and expeller seals, offering flexibility and precision.
Flexible couplings
In contrast to rigid couplings, our flexible couplings are designed to adeptly accommodate movements like vibrations and thermal expansion without incurring damage. Their suitability shines in applications with inevitable slight misalignments between drive and pump shafts. By adeptly absorbing vibrations, they significantly reduce excess operating noise. Despite a more intricate, costlier design, the long-term benefits of flexible couplings include maintenance savings due to their protection of shafts and bearings from damage and premature wear.
Our selection features wear-resisting disc coupling or pin coupling, each designed for exceptional durability and performance.
