The IH end-suction pump from Shanghai Semhai Pump Co., Ltd. is a state-of-the-art, single-stage, single-suction (axial suction) cantilever centrifugal marvel, designed to convey corrosive liquids with water-like viscosity sans solid particles. Crafted to align with the esteemed ISO2858 international standards, this pump boasts a stunning array of features including a vast performance spectrum, exceptional efficiency, and hassle-free maintenance. Notably, it shines with an impressive 5 percent efficiency boost over the F-type pump, making it a globally recognized energy-saving innovation.
The IH chemical pump is engineered to handle transmission medium temperatures ranging from -20 ºC to 105 ºC, and if necessary, its adaptability allows the transport of even higher temperature mediums with enhanced cooling solutions. Perfectly suited for diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers, it excels at transporting various corrosive media akin to water, all the while ensuring zero pollution.
Main Design Features
Uncompromising in its adaptability, this pump is ideal for high-pressure applications with its robust flanges rated at PN 10 and PN 16, ensuring reliable performance.
The innovative 'Back pull-out' design facilitates easy removal of hydraulic components, eliminating the need to detach the pump body from plant pipes during maintenance.
Equipped with a dynamically balanced closed impeller, this pump minimizes radial loads, ensuring a seamless and smooth rotation of the impeller under all conditions.
Its suction profile is meticulously designed to significantly reduce NPSH, guaranteeing trouble-free operations even in the most demanding conditions.
Constructed with a high-grade stainless steel shaft, it is built to endure and excel under significant bending-torsion loads.
The use of oversized ball bearings results in remarkably low working noise levels and extends the service life of the pump exponentially.
A broad selection of mechanical seals or gland packings (SES) is available, each meticulously configured to meet the unique requirements of fluid characteristics and operational conditions, thereby ensuring optimal performance.

To expertly balance the axial thrust in our pumps, we incorporate wear rings both in front and at the back of most impellers, complemented by a balance hole on the back shroud of the impeller. In pumps where the axial thrust is not significant, these components are unnecessary, ensuring a streamlined design without a wear ring and balance hole at the back.
The high-precision casting of our impeller is meticulously crafted to guarantee peak performance. We offer a choice of robust materials, including cast iron, durable stainless steel, and elegant bronze.
Our packing pump cover is ingeniously fitted with stuffing for the soft packing seal. This design allows for a specific pressure of water to circulate through the stuffing, ensuring optimal seal cooling, effective lubrication, and thorough cleaning.
Offering versatility, we provide single and double mechanical seals. These seals operate by channeling water under a certain pressure into the seal cavity, which rinses the end surface friction and provides a cooling effect. For enhanced customization, our design accommodates ISO3069 structures, such as a mechanical seal with a corrugated pipe and expeller seal, for a tailored fit.
Flexible Couplings
Flexible couplings are engineered to endure slight movements such as vibrations and thermal expansions, making them perfect for situations where unavoidable misalignment occurs between drive and pump shafts. Their ability to absorb vibrations significantly reduces operational noise. Although they entail a more intricate and costly design, the long-term benefits are substantial, as they safeguard the shaft and bearings from undue harm and wear, thereby reducing maintenance costs over time.
Our commitment to quality is demonstrated through the use of wear-resistant disc couplings or pin couplings, both designed to withstand rigorous operational demands.
