The IH end-suction pump stands as a remarkable feat of engineering, boasting a single-stage, single-suction (axial suction) cantilever centrifugal design. This pump is adept at handling corrosive liquids with a viscosity akin to water, all while ensuring that no solid particles are present. Built in strict adherence to the prestigious international standards of ISO2858, this pump is characterized by its exceptional performance range, superior efficiency, and simplified maintenance. In fact, it delivers an average of 5 percent higher efficiency compared to the traditional F-type pump, firmly establishing itself as a leading energy-saving product on the global stage.
The IH chemical pump is a versatile powerhouse capable of handling transmission medium temperatures ranging from -20 ºC to 105 ºC. With the potential for higher temperature media when equipped with enhanced cooling measures, this pump is ideal for a multitude of industries including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. Its design ensures the safe conveyance of various corrosive media similar to water, all while maintaining an unwavering commitment to preventing pollution.
Main Design Features
Engineered for high-pressure applications, this pump integrates flanges conforming to PN 10 and PN 16 standards, ensuring reliable performance even under intense conditions.
Featuring an innovative 'Back pull-out' design, this pump allows for the effortless removal of hydraulic components without necessitating the detachment of the pump body from your facility's piping system.
The dynamically balanced closed impeller is meticulously crafted to minimize radial loads, ensuring a smooth and seamless rotation for optimal performance.
Its uniquely engineered suction profile effectively reduces NPSH, guaranteeing trouble-free operation even in the most demanding conditions.
Constructed from robust stainless steel, the shaft is expertly designed to endure significant bending and torsion loads, enhancing overall durability and performance.
The inclusion of oversized ball bearings not only diminishes operational noise but also substantially extends the pump's service life, promising reliability and longevity.
A comprehensive selection of mechanical seals or gland packings (SES) is available, tailored to meet the specific demands of fluid characteristics and operational conditions, offering unmatched versatility and adaptability.

To impeccably balance axial thrust, our sophisticated system incorporates robust wear rings positioned both in front and behind the impeller, alongside an ingeniously placed balance hole on the back shroud of the impeller. For some pumps where the axial thrust is deemed minimal, the design strategically omits the rear wear ring and balance hole, optimizing efficiency without compromising performance.
Our high-precision casting impellers are meticulously crafted to ensure optimal performance. Available in cast iron, stainless steel, and bronze, these impellers embody both reliability and durability, meeting the diverse demands of various applications.
The packing pump cover is equipped with a specially designed stuffing for a soft packing seal. This innovative feature allows the stuffing to channel a precise pressure of water, serving the dual purpose of seal cooling and lubrication, as well as maintaining cleanliness.
Offering unmatched versatility, our system supports both single and double mechanical seals. These seals allow a calibrated pressure of water into the seal cavity, effectively reducing end surface friction while providing a cooling effect. Adhering to ISO3069 standards, our seals can adapt to a variety of structures, including those with corrugated pipes and expeller seals, ensuring that your specific needs are met with precision and excellence.
Flexible Couplings
Flexible couplings are engineered to seamlessly accommodate movement such as vibrations and thermal expansion, unlike their rigid counterparts. This adaptability makes them perfect for scenarios where there is inevitable misalignment between drive and pump shafts. Besides reducing excessive operating noise, flexible couplings absorb vibrations efficiently, translating to a quieter operation. While their design may be more complex and costly, the long-term benefits of protecting shafts and bearings from damage and premature wear translate to significant maintenance savings.
For optimal performance and durability, we utilize wear-resisting disc couplings or pin couplings, ensuring reliability and longevity in demanding applications.
