Introducing the IH end-suction pump, an exceptional single-stage, single-suction (axial suction) cantilever centrifugal masterpiece. Specifically crafted for conveying corrosive liquids, its viscosity mirrors that of water and it remains free from solid particles. Engineered in alignment with international standards ISO2858, this marvel boasts a broad spectrum of performance, unparalleled efficiency, and effortless maintenance. Astoundingly, it elevates efficiency by an average of 5% compared to the F-type pump, marking it as a globally acclaimed energy-saving innovation.
The IH chemical pump is versatile, adeptly handling transmission media temperatures from -20 ºC to 105 ºC. With advanced cooling measures, it can even transport higher temperature media. This makes it perfect for a plethora of industries-chemical, petroleum, metallurgy, electric power, paper, food, pharmaceuticals, and synthetic fibers. It delivers corrosive media akin to water, all without pollution, ensuring seamless industrial applications.
Main Design Features
Expertly built for high-pressure applications, equipped with robust flanges in PN 10 and PN 16, ensuring peak performance in demanding environments.
The ingenious 'Back pull-out' design enables swift removal of hydraulic components without detaching the pump body from plant pipes, ensuring minimal disruption and maximum convenience.
A dynamically balanced closed impeller expertly minimizes radial loads, guaranteeing smooth, reliable rotation and extending the longevity of the impeller.
The precision-engineered suction profile significantly reduces NPSH, ensuring trouble-free operation even in the most demanding conditions.
Crafted from stainless steel, the shaft is designed to endure bending-torsion loads, ensuring durability and reliability throughout its service life.
Oversized ball bearings not only diminish operational noise but also promise an extended service life, enhancing overall user experience.
A vast selection of mechanical seals or gland packings (SES) is available, meticulously chosen to meet the specific requirements of fluid characteristics and operational conditions.

To expertly balance axial thrust, our pumps feature precision-engineered wear rings positioned both in front and at the rear of the impeller, complemented by a balance hole strategically located on the back shroud of the impeller. While some pumps have minimal axial thrust and do not require these components, this innovative design element ensures optimal performance and reliability.
Our high-precision casting impellers are meticulously crafted to guarantee exceptional performance, available in premium materials such as cast iron, stainless steel, and bronze.
The packing pump cover is adeptly fitted with stuffing to facilitate a soft packing seal. This mechanism allows the stuffing to pass through a regulated pressure of water, providing essential seal cooling, lubrication, and cleaning.
Offering versatility, we provide both single and double mechanical seals. These seals introduce water into the seal cavity under specific pressure, ensuring the end surface is rinsed and cooled to perfection. Adhering to ISO3069 standards, we accommodate various structures such as mechanical seals with corrugated pipes and expeller seals, fulfilling diverse operational demands.
Flexible Couplings
In contrast to rigid couplings, our advanced flexible couplings are designed to gracefully accommodate movements, including vibrations and thermal expansion, preventing potential damage. Ideal for scenarios requiring alignment flexibility between drive and pump shafts, these couplings absorb vibrations efficiently, significantly reducing operational noise. While they feature a more intricate and costly design, their ability to safeguard shafts and bearings from damage and premature wear translates to significant long-term maintenance savings.
We proudly implement durable wear-resisting disc couplings or pin couplings for enhanced performance and longevity.
