ISG single-stage single-suction centrifugal pump

I. Overview

ISG vertical centrifugal pump is used for conveying other liquids with physical and chemical properties similar to clear water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurization water supply, garden sprinkler irrigation, fire pressurization, long-distance conveying, HVAC refrigeration cycle, bathroom and other cold and warm water circulation pressurization and equipment matching. The working temperature is T <80℃.

IRG (RGR) vertical hot water (high temperature) circulating pump is widely used in energy, metallurgy, chemical industry, textile, paper making, hotels and restaurants boiler high temperature hot water pressure circulating conveying and city heating system circulating pump. IRG working temperature is T <120℃, and RGR working temperature is T <240℃.

IHG vertical chemical pump is used for conveying liquid which contains no solid particles, is corrosive and has viscosity similar to water. It is suitable for petroleum, chemical industry, metallurgy, electric power, paper making, food, pharmacy and synthetic fiber department, and the working temperature is -20℃-+120℃
