The IH end-suction pump, a marvel of engineering, is a single-stage, single-suction (axial suction), cantilever centrifugal pump. It expertly conveys corrosive liquids with a viscosity similar to water, free from solid particles. Its performance, marked and rated in strict accordance with international standards ISO2858, boasts a wide performance range. This pump is not only high in efficiency but also easy to maintain, offering an impressive average efficiency increase of 5 percent compared to the F-type pump. It stands as an internationally promoted energy-saving product.
The IH chemical pump is equipped to handle transmission media temperatures ranging from -20 ºC to 105 ºC. Capable of transporting media at even higher temperatures when enhanced with advanced cooling measures, this pump is indispensable across industries such as chemical processing, petroleum, metallurgy, electric power, paper production, food processing, pharmaceuticals, and synthetic fibers. It proficiently transports a variety of corrosive media similar to water without causing pollution.
Main Design Features
Expertly crafted for high-pressure applications, the pump features robust flanges rated at PN 10 and PN 16.
The innovative 'Back pull-out' design facilitates the removal of hydraulic components without necessitating the detachment of the pump body from plant piping.
A dynamically balanced closed impeller is incorporated to minimize radial loads, ensuring seamless impeller rotation.
Ingeniously designed suction profile minimizes NPSH, guaranteeing trouble-free operation even under demanding conditions.
The stainless steel shaft is meticulously engineered to endure significant bending-torsion loads.
Oversized ball bearings are employed to significantly reduce operational noise and extend the pump's service life.
A vast array of mechanical seals or gland packings (SES) are available, each carefully configured to meet the specific characteristics and usage conditions of the fluid.

To artfully balance the axial thrust in our pumps, we incorporate wear rings both at the forefront and rear of most impellers, complemented by a precision-crafted balance hole on the impeller's back shroud. However, for certain models with naturally lower axial thrust, the design is optimized to exclude rear wear rings and balance holes, enhancing efficiency without compromising performance.
Our impellers, forged with high-precision casting techniques, boast exceptional performance and durability. You can select from a range of materials including robust cast iron, corrosion-resistant stainless steel, and durable bronze to perfectly suit your specific application needs.
The packing pump cover is ingeniously equipped with stuffing designed for a soft packing seal. This allows for the introduction of pressurized water to the stuffing, effectively ensuring seal cooling, lubrication, and cleaning, thus extending the lifespan and functionality of the pump.
We offer two sophisticated types of mechanical seals: single and double. These seals operate with a designated pressure of water introduced into the seal cavity, meticulously rinsing the end surface to reduce friction while providing a cooling effect. Furthermore, our design accommodates ISO3069 standards for adapting sealed cavities to specific requirements, including options like corrugated pipe mechanical seals and expeller seals.
Flexible Couplings
Unlike their rigid counterparts, flexible couplings elegantly accommodate slight movements such as vibrations and thermal expansion without sustaining damage. This flexibility makes them ideal for scenarios involving unavoidable misalignment between drive and pump shafts. They not only absorb vibrations, reducing operational noise, but also offer long-term maintenance savings by protecting shafts and bearings from wear and tear, despite a more intricate and costly initial design.
Our pumps are enhanced with wear-resisting disc couplings or pin couplings, ensuring reliability and longevity in demanding environments.
