1, IHW horizontal stainless steel pipe centrifugal pump for conveying water and physical and chemical properties similar to other liquids for water use, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, irrigation, fire booster and equipment package , The use of temperature T: ≤ 80 ℃. 2, ISWR (WRG) hot water (high temperature) circulating pump is widely used in energy, metallurgy, chemical industry, textile, papermaking, hotels and restaurants boilers and other high-temperature hot water circulation pump circulation and urban heating system circulating pump, ISWR temperature T: ≤ 120 ℃, WRG temperature T: ≤ 240 ℃. 3, ISWH horizontal chemical pump, for the delivery of non-solid particles, corrosive, viscosity similar to the liquid water for petroleum, chemical, metallurgical, power, paper, food, pharmaceutical and synthetic fiber and other departments, the use of temperature T: -20 ° C to 120 ° C. 4, ISWB horizontal oil pump for the transportation of petrol, diesel, kerosene and other petroleum products, the use of temperature T: -20 ℃ -120 ℃. IHW horizontal stainless steel pipe centrifugal pump working conditions 1, suction pressure ≤ 1.0Mpa, or the maximum working pressure of the pump system ≤ 1.6Mpa, that is, the suction pressure of the pump + pump head ≤ 1.6Mpa, pump static pressure test pressure 2.5Mpa, order Please indicate the system pressure. Pump system working pressure greater than 1.6Mpa should be made separately when ordering. So that the pump's overcurrent and coupling parts are cast steel when manufactured. 2, Ambient temperature 3, the volume of solid particles in the conveying medium does not exceed 0.1% of the unit volume, particle size Note: If the medium used is with small particles, please specify when ordering, in order to wear-resistant mechanical seal.
