The IH end-suction pump from Shanghai Semhai Pump Co., Ltd. is a remarkable single-stage, single-suction (axial suction) cantilever centrifugal pump. It is engineered to efficiently convey corrosive liquids with a viscosity akin to water, devoid of solid particles. Modeled in compliance with the global ISO2858 standards, it showcases an impressive array of performance capabilities, heightened efficiency, and effortless maintenance. With an efficiency boost averaging 5% over traditional F-type pumps, this pump stands as a beacon of energy conservation and innovation on the international stage.
The IH chemical pump's transmission medium is capable of handling temperatures from -20 ºC to 105 ºC. For applications requiring higher temperatures, enhanced cooling options ensure optimal performance. This pump is perfect for diverse industries such as chemicals, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It adeptly manages the conveyance of a wide array of corrosive media, all while ensuring the purity of water-like substances without pollution.
Main Design Features
Engineered for high-pressure scenarios, this pump is compatible with flanges rated at PN 10 and PN 16, ensuring versatility and reliability.
Featuring a 'back pull-out' design, this pump facilitates the removal of hydraulic components without necessitating the disassembly of the pump body from plant piping, streamlining maintenance procedures.
The impeller is dynamically balanced and enclosed to minimize radial loads, ensuring seamless and efficient rotation, thereby enhancing the pump's operational longevity.
Crafted with a suction profile that effectively reduces NPSH, this design guarantees trouble-free operation even under the most challenging conditions.
The stainless steel shaft is meticulously designed to endure bending-torsion loads, ensuring durability and reliability in demanding applications.
Oversized ball bearings are incorporated to significantly reduce operational noise while extending the pump's service life, offering a whisper-quiet, reliable performance.
A vast array of mechanical seals and gland packings (SES) are available, tailored to the specific characteristics and conditions of the fluid in use, ensuring a comprehensive sealing solution for every application.

To expertly counteract axial thrust, our design features wear rings both at the front and rear of most impellers, complemented by a strategically placed balance hole on the back shroud of the impeller. For pumps where axial thrust is minimal, the use of rear wear rings and balance holes becomes unnecessary, streamlining the design.
Our high-precision casting impeller is crafted to guarantee superior performance. It is available in an array of robust materials such as cast iron, stainless steel, and bronze, ensuring both durability and reliability.
The packing pump cover is ingeniously designed with stuffing for a soft packing seal. This setup allows water under certain pressure to flow through, providing essential cooling, lubrication, and cleaning to the seal, enhancing its lifespan and effectiveness.
Our mechanical seal solutions include two options: single and double mechanical seals. By introducing water at a specific pressure into the seal cavity, we effectively rinse the end surface friction while providing a cooling effect. This flexibility allows adaptation to various ISO3069 structures, including mechanical seals with corrugated pipes and expeller seals, matching specific requirements seamlessly.
Flexible Couplings
Flexible couplings provide a perfect solution for systems requiring movement accommodation, such as vibrations and thermal expansion, without risking damage. They are ideal for slight misalignments between drive and pump shafts, effectively absorbing vibrations, and minimizing operating noise. Although more complex and costly, these couplings protect shafts and bearings from damage and premature wear, translating into significant maintenance savings over time.
For optimal performance, we employ wear-resisting disc couplings or pin couplings, chosen for their durability and ability to withstand demanding conditions.
This exceptional product finds its versatile application across a multitude of domains, ensuring efficiency and reliability. It's extensively employed in urban water supply and drainage systems, offering optimal solutions for central heating and drainage projects.
