The IH end-suction pump is a cutting-edge, single-stage, single-suction cantilever centrifugal pump, meticulously engineered to handle corrosive liquids with water-like viscosity while being free of solid particles. It boasts international standards conformity, aligning with ISO2858 for unparalleled reliability. This pump stands out with its broad performance range, remarkable efficiency, and user-friendly maintenance. Notably, its efficiency surpasses that of the conventional F-type pump by an average of 5%, positioning it as a globally endorsed energy-saving marvel.
The IH chemical pump is adept at transmitting media across a temperature spectrum of -20 ºC to 105 ºC. For even higher temperature media, enhanced cooling measures can be employed, making it perfectly suited for a myriad of industries including chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber. It expertly handles all varieties of water-like corrosive media, ensuring no pollution or contamination, thus meeting the stringent demands of these industrial sectors.
Main Design Features
Engineered for high-pressure scenarios, this pump is compatible with flanges rated at PN 10 and PN 16, ensuring robust and reliable performance under demanding conditions.
The innovative "Back pull-out" design allows for hassle-free removal of hydraulic components without detaching the pump body from plant pipes, significantly simplifying maintenance processes.
A dynamically balanced closed impeller is incorporated to effectively minimize radial loads, ensuring the impeller rotates smoothly for optimal performance and longevity.
The carefully crafted suction profile is designed to reduce Net Positive Suction Head (NPSH), guaranteeing trouble-free operation even in the most challenging environments.
Crafted from stainless steel, the shaft is meticulously designed to endure bending-torsion loads, offering unmatched durability and longevity in demanding applications.
Equipped with oversized ball bearings, this pump significantly reduces operational noise while providing an extended service life, ensuring a quiet and efficient pumping experience.
A broad selection of mechanical seals or gland packings (SES) can be configured to precisely meet the fluid characteristics and operational conditions, offering tailored solutions for diverse industrial needs.

To achieve the perfect balance of axial thrust, we have ingeniously incorporated wear rings at both the front and rear of most impellers, accompanied by a strategically placed balance hole on the back shroud. However, in some of our pumps, the axial thrust is minimal, abolishing the need for a rear wear ring or balance hole.
Our precisely cast impellers, crafted with the utmost precision in materials such as cast iron, stainless steel, and bronze, are designed to consistently deliver exceptional performance.
The packing pump cover is meticulously equipped with a soft packing seal. This innovative design allows the stuffing to be cooled, lubricated, and cleaned by channeling water at a specific pressure, ensuring seamless operation.
The mechanical seal options feature both single and double mechanical seals. These state-of-the-art seals function by introducing a precise pressure of water into the sealing cavity, effectively rinsing the end surface to minimize friction while providing exceptional cooling. Additionally, we offer a versatile sealed cavity design that accommodates ISO3069 specifications, including mechanical seals with corrugated pipes and expeller seals.
Efficient and Adaptable Flexible Couplings
Flexible couplings stand out from rigid couplings with their remarkable ability to handle minor movements, such as vibrations and thermal expansion, without sustaining damage. This makes them the go-to choice for scenarios with unavoidable misalignment between drive and pump shafts. They excel in absorbing vibrations, significantly reducing operational noise. Though flexible couplings come with a more intricate and costly design, they offer the long-term advantage of safeguarding shafts and bearings from damage and premature wear, contributing to considerable maintenance cost savings.
For optimum durability, we utilize wear-resistant disc couplings or pin couplings.
