The IH end-suction pump stands as a pinnacle of engineering precision, crafted as a single-stage, single-suction (axial suction) cantilever centrifugal pump. Designed to convey corrosive liquids with viscosities akin to water, it ensures smooth transfer without solid particles interference. Boasting international compliance with ISO2858 standards, it exemplifies a harmonious blend of wide-ranging performance, heightened efficiency, and effortless maintenance. Notably, its efficiency surpasses the conventional F-type pump by an average of 5%, establishing it firmly as a globally acclaimed energy-saving marvel.
Engineered to operate within a temperature range of -20 ºC to 105 ºC, the IH chemical pump effortlessly transports mediums of higher temperatures when equipped with advanced cooling measures. This adaptability makes it an ideal choice across a spectrum of industries—chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It seamlessly transfers corrosive media, maintaining purity akin to water, thus embodying versatility and reliability without pollution.
Main Design Features
Expertly crafted for high-pressure environments, with flanges available in PN 10 and PN 16, ensuring robust performance across demanding applications.
The innovative "Back pull-out" design redefines convenience by allowing the removal of hydraulic components without detaching the pump body from plant pipes, ensuring operational efficiency and ease of maintenance.
A dynamically balanced closed impeller, meticulously designed, reduces radial loads, facilitating smooth and unobstructed impeller rotation for optimal performance.
Engineered with a precision suction profile, it effectively diminishes NPSH, guaranteeing seamless operation even in the most challenging conditions.
A robust stainless steel shaft is crafted to endure bending-torsion loads, enhancing durability and reliability in every application.
The inclusion of oversized ball bearings not only minimizes working noise but also significantly extends the service life of the pump, ensuring long-term efficiency.
Offering a diverse selection of mechanical seals or gland packings (SES), each configured to align with fluid characteristics and operational conditions, caters to a wide range of functional requirements.

To expertly balance axial thrust, precision-engineered wear rings are positioned at both the front and back of most impellers, complemented by a strategically placed balance hole on the impeller's back shroud. In instances where the axial thrust is minimal, the design is streamlined by omitting the wear ring and balance hole at the back, ensuring optimal performance without unnecessary components.
Our high-precision casting impeller guarantees superior performance. Available in durable cast iron, corrosion-resistant stainless steel, and classic bronze, these materials ensure longevity and efficiency under various operating conditions.
The packing pump cover is ingeniously designed with stuffing for a soft packing seal, allowing the infusion of a controlled water pressure for efficient seal cooling, lubrication, and cleaning. This meticulous design enhances operational reliability and minimizes maintenance.
Our advanced mechanical seal options include both single and double configurations, designed for versatility and performance. Water is introduced under specific pressure into the seal cavity to rinse and cool end surface friction effectively. Furthermore, our design accommodates ISO3069 standards, offering flexible options like corrugated pipe and expeller seal adaptations for varied operational requirements.
Flexible Couplings
Flexible couplings are engineered to expertly manage movements, such as vibrations and thermal expansion, without sustaining damage. Ideal for scenarios with inevitable misalignment between drive and pump shafts, they significantly dampen vibrations, reducing operational noise. Although their design is more complex and costly, the long-term benefits include safeguarding shafts and bearings from damage and reducing maintenance costs, ensuring a sound investment.
Our selection includes wear-resistant disc coupling or pin coupling, tailored for durability and optimal performance.
