The IH end-suction pump by Shanghai Semhai Pump Co., Ltd. is a marvel of engineering—a single-stage, single-suction (axial suction), cantilever centrifugal pump. It's expertly designed to convey corrosive liquids with a viscosity similar to water, ensuring no solid particles disrupt its smooth operation. This cutting-edge pump meets the international ISO2858 standards for mark, rated performance, and sizing, boasting a broad performance range, elevated efficiency, and ease of maintenance. Notably, it achieves an average 5% higher efficiency compared to the F-type pumps, positioning it as an internationally acclaimed energy-saving solution.
The IH chemical pump showcases exceptional versatility with its operational temperature range from -20 ºC to 105 ºC. For even higher temperature mediums, enhanced cooling measurements can be applied, making it ideal for industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It adeptly handles transporting all kinds of corrosive media akin to water, safeguarding against pollution and ensuring seamless performance across diverse sectors.
Main Design Features
Engineered for high-pressure applications, the IH pump is compatible with flanges rated in PN 10 and PN 16, ensuring robust and reliable performance.
The innovative "Back pull-out" design enables the effortless removal of hydraulic parts without detaching the pump body from the plant pipelines, enhancing operational efficiency and maintenance simplicity.
Featuring a dynamically balanced closed impeller, this pump significantly minimizes radial loads, facilitating the smooth and seamless rotation of the impeller.
The suction profile is meticulously crafted to lower NPSH, ensuring trouble-free, uninterrupted operation even under the most demanding conditions.
Crafted from stainless steel, the shaft is designed to expertly withstand bending-torsion loads, offering unparalleled durability and strength.
Oversized ball bearings are integrated to provide reduced working noise and an extended service life, ensuring a tranquil and long-lasting operational experience.
A vast selection of mechanical seals or gland packings (SES) is available, carefully configured to align with the fluid's characteristics and the conditions of use, offering tailored solutions for optimal performance.

To masterfully balance axial thrust, the majority of the impeller is ingeniously designed with wear rings positioned both in front and at the back, while the back shroud of the impeller features a strategic balance hole. However, for pumps where axial thrust is minimal, there is no necessity for a rear wear ring and balance hole.
The impeller boasts high-precision casting to guarantee optimal performance, available in top-quality materials such as cast iron, stainless steel, and bronze.
The packing pump cover comes adeptly equipped with stuffing for a soft packing seal. The stuffing may channel a certain pressure of water, ensuring seal cooling, lubrication, and cleanliness.
Choose between single mechanical seal and double mechanical seal options, both engineered for high efficiency. Water is introduced into the seal cavity at a specified pressure to cleanse and cool the friction-prone end surface. Adapt to specific needs by utilizing the cavity to form various ISO3069 structures, such as the advanced mechanical seal with corrugated pipe or the expeller seal.
Flexible Couplings
Flexible couplings offer superior adaptability over rigid couplings by accommodating vibrations and thermal expansion without sustaining damage. Perfect for applications requiring misalignment between drive and pump shafts, they excel in minimizing excessive operating noise by absorbing vibrations. Though more intricate and costly, their ability to protect shafts and bearings from early wear translates to maintenance cost savings over time.
Our selection includes wear-resisting disc couplings or pin couplings for enhanced durability.
