The IH End-Suction Pump is a single-stage, single-suction (axial suction) cantilever centrifugal pump, expertly engineered to convey corrosive liquids with a viscosity akin to water, free from any solid particles. Crafted to meet the esteemed international standards of ISO2858, this pump boasts an impressive array of features including a broad performance range, exceptional efficiency, and ease of maintenance. Remarkably, it offers an average efficiency increase of 5 percent compared to the F-type pump, positioning it as a globally recognized energy-saving marvel.
The IH chemical pump is capable of transmitting mediums within a temperature range of -20 ºC to 105 ºC. For scenarios requiring the transportation of higher-temperature mediums, enhanced cooling measures can be employed. It is adept for use in diverse industries such as chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fibers, making it ideal for transporting a variety of corrosive media similar to water without causing any pollution.
Main Design Features
Perfectly suited for high-pressure applications, the design includes flanges in PN 10 and PN 16 that ensure robust functionality under demanding conditions.
The ingenious 'Back Pull-Out' design facilitates the effortless removal of hydraulic components without the necessity of detaching the pump body from the plant pipes, streamlining maintenance and minimizing downtime.
A dynamically balanced closed impeller is incorporated to minimize radial loads and ensure the smooth and efficient rotation of the impeller, enhancing overall performance.
The precision-engineered suction profile is tailored to reduce Net Positive Suction Head (NPSH), ensuring seamless, trouble-free operations even in the most demanding conditions.
The stainless steel shaft is meticulously designed to endure the complex bending-torsion load, guaranteeing durability and reliable performance.
Oversized ball bearings are utilized to significantly lower working noise and extend the service life, providing a quiet and long-lasting operational experience.
A vast selection of mechanical seals or gland packings (SES) is available, meticulously configured to align with the specific requirements of fluid characteristics and usage conditions, ensuring optimal performance and reliability.

To expertly balance axial thrust, our robust design integrates wear rings at both the front and back of most impellers, complemented by a balance hole on the impeller's rear shroud. In certain models where the axial thrust is minimal, these features might not be included, ensuring only necessary components are used for maximum efficiency.
Our precision-crafted impellers, available in materials such as cast iron, stainless steel, and bronze, guarantee unparalleled performance. Through high-precision casting, we ensure each impeller meets the stringent standards of durability and efficiency.
The innovative packing pump cover is outfitted with specialized stuffing for a soft packing seal. This design allows the introduction of water at a controlled pressure to maintain seal cooling, lubrication, and cleanliness, paving the way for seamless operation.
Our pumps feature options for both single and double mechanical seals. These seals effectively introduce water to the seal cavity under pressure, enhancing cooling and reducing end surface friction. Designed to adapt to ISO3069 standards, our seals can also incorporate advanced structures like corrugated pipe seals and expeller seals, ensuring versatility and adaptability to diverse operational needs.
Flexible couplings
In contrast to rigid couplings, our flexible couplings excel at accommodating movement such as vibrations and thermal expansion, thereby preventing damage. This makes them ideal for scenarios with inevitable misalignments between the drive and pump shafts. Their superior vibration absorption capabilities significantly reduce operational noise, despite their more complex and costly design. Over time, these couplings provide substantial maintenance savings by safeguarding the shaft and bearings from damage and premature wear.
We incorporate wear-resistant disc couplings or pin couplings, ensuring enduring reliability and performance in demanding conditions.
