The IH end-suction pump stands as a beacon of innovation, embodying a single-stage, single-suction (axial suction) cantilever centrifugal design. It is engineered to transport corrosive liquids with a viscosity akin to water, free of solid particles. This marvel aligns with the esteemed international standards of ISO2858, offering an expansive spectrum of performance, enhanced efficiency, and straightforward maintenance. Notably, it boasts an average efficiency that is 5% superior to the F-type pump, representing a significant stride in globally promoted energy-saving solutions.
The IH chemical pump is a versatile powerhouse, capable of transmitting medium temperatures ranging from -20 ºC to 105 ºC. With additional cooling measures, it efficiently handles higher temperature mediums. This makes it an indispensable asset across diverse industries—chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber—specializing in the safe transport of various corrosive media, akin to water, without causing pollution.

To expertly balance axial thrust, our innovative design includes wear rings both in front and at the back of most impellers, complemented with a strategically placed balance hole on the impeller's back shroud. For pumps where axial thrust is minimal, they are crafted without the need for a rear wear ring and balance hole, maintaining efficiency without compromise.
Our high-precision casting impeller guarantees superior performance and reliability, crafted from robust materials such as cast iron, stainless steel, and bronze to meet diverse application needs.
The packing pump cover is ingeniously equipped with soft packing seals. The stuffing allows for water under specific pressure to circulate for cooling, lubrication, and cleaning, ensuring the pump operates smoothly and efficiently.
Our mechanical seals come in two sophisticated types: single and double. A controlled water pressure enters the seal cavity, cleansing the end surface to reduce friction and provide excellent cooling. Customization is available with predetermined ISO3069 structures, including mechanical seals with corrugated pipes and expeller seals, to meet your precise requirements.
Flexible Couplings
Flexible couplings, unlike their rigid counterparts, excel in accommodating movement, such as vibrations and thermal expansion, without sustaining damage. This capability makes them perfect for scenarios with inherent misalignment between drive and pump shafts. Their impressive vibration absorption significantly reduces operating noise. Despite a more complex and costly design, flexible couplings offer substantial maintenance savings by safeguarding shafts and bearings against premature wear and damage.
We incorporate wear-resisting disc coupling or pin coupling for optimal performance.
