ISG, IRG, GRG, IHG, YG, TEB series of single-suction single-pipe vertical pipeline centrifugal pump, using IS pump performance parameters, hydraulic model. Pump one, out of the same diameter and at the same level, the shaft seal with a mechanical seal. TEB is the latest product developed by our factory due to the restriction of space and lifting equipment due to user's maintenance of pump. 1, ISG-type pipeline pump for heating and air conditioning systems, hot and cold water circulation, high-rise building water supply, fire pipeline pressurization, long distance water delivery, industrial production process of circulating pressure, garden sprinkler, the media is clear water or physical, chemical properties similar Other media in water. Medium temperature does not exceed 80 ℃. 2, IRG-type hot water pipeline centrifugal pump is mainly used for hot and cold water circulation in the greenhouse, boiler, bathroom, non-corrosive hot water pressurization cycle in various industries. Medium temperature does not exceed 150 ℃. 3, GRG-type high-temperature pipeline centrifugal pump is mainly used for boiler water supply and drainage cycles, hot and cold water circulation, heating and other industries without corrosive high temperature liquid. Medium temperature does not exceed 200 ℃. 4, IHG chemical pipeline centrifugal pump is mainly used for chemical industry, environmental protection, equipment brewing, pharmaceutical, papermaking, textile and other industries booster, chemical delivery of corrosive liquids. Medium temperature does not exceed 100 ℃ 5, YG pipe pump for the transportation of solid particles, viscosity less than 120 centistar non-corrosive oils and petroleum products. Transmission medium temperature is -20 ~ 80 ℃. 6, TEB for demolished vertical pipe pump, change the material can be applied to a variety of working conditions above. Performance Range Flow: 5.6 ~ 720m³ / h Head: 5 ~ 125m Maximum working pressure: 1.6MPa (200 and below), 1.0MPa (200 and above) Import pressure ≤ 0.3MPa (when ordering over 0.3MPa should be specified) Import and export of ISG, IRG, GRG, IHG, YG and TEB series pipe pumps are the same in size and in the same horizontal direction with each other at 180 ℃. Pumps are the main components of the pump body, pump cover, impeller, seal ring, motor bracket, pump and motor coaxial (TEB-type independent pump shaft) seal with high-quality mechanical seal. From the motor end, the pump rotates clockwise. Material: cast iron; cast steel; cast stainless steel
