The IRG/IHG series are vertical single-stage single-suction pipeline centrifugal pumps featuring a coaxial integrated structure. With identical inlet and outlet diameters, they can be directly installed in series on pipelines just like valves.The pump shaft features high concentricity, and the impeller achieves superior dynamic and static balance, ensuring stable and vibration-free operation. Equipped with hard alloy mechanical seals, the pumps realize zero leakage during operation. Matched with low-noise bearings, they deliver ultra-low operating noise. Adopting a simple and reasonable structural design, the pumps have a low failure rate and allow easy and convenient maintenance when replacing seals, bearings and other wearing parts.
IRG/IHG vertical pipeline centrifugal pumps are designed to convey clean water and media with physical and chemical properties similar to clean water. They are widely applicable for industrial and urban water supply and drainage, pressurized water delivery for high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance water transmission, HVAC cooling and heating circulation, as well as cold and hot water circulation pressurization for bathrooms.Hot water type pumps are suitable for pressurized transportation of high-temperature boiler hot water and urban heating systems in metallurgy, chemical, textile, papermaking, hotel and catering industries. Chemical type pumps can deliver solid-free corrosive liquids with viscosity equal to or higher than water, and are extensively used in petroleum, chemical, metallurgical, electric power, papermaking, food, pharmaceutical and synthetic fiber industries.
