The ISWR/IHW series are horizontal single-stage single-suction pipeline centrifugal pumps with coaxial integrated structure. Featuring identical inlet and outlet calibers, they can be directly connected in series into pipelines just like valves.The pump shaft boasts high concentricity, and the impeller achieves excellent dynamic and static balance, enabling stable vibration-free operation. Equipped with hard alloy seals, the pumps ensure zero leakage. Fitted with low-noise bearings, they run quietly. Simple and reasonable in structure, they have a low failure rate and allow convenient maintenance for replacing seals, bearings and other components.

ISWR/IHW horizontal pipeline centrifugal pumps can deliver clean water and media with physical and chemical properties similar to clean water. They are suitable for industrial and urban water supply & drainage, pressurized water delivery for high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration circulation, and cold & hot water circulation pressurization for bathrooms.Hot-water models are used for pressurized transportation of high-temperature boiler hot water and urban heating systems in metallurgy, chemical, textile, papermaking, hotels and restaurants. Chemical versions can convey corrosive liquids free of solid particles with viscosity similar to or higher than water, widely applied in petroleum, chemical, metallurgical, power, papermaking, food, pharmaceutical and synthetic fiber industries.
