ISG - Single-stage single-suction vertical pipeline centrifugal pump 
 Product Overview: 
 ISG - Series single stage single suction pipeline centrifugal pump, is the scientific and technical personnel of the unit of the United Nations pump experts selected domestic excellent hydraulic model, the performance parameters of the IS type centrifugal pump, vertical pump on the basis of a clever combination designed ISG - depending on the use of temperature, medium derived from the application of hot water, high temperature, corrosive chemical pump, oil pump. This series of products with high efficiency, low noise, reliable performance. 
 Product Features: 
 1, the pump for the vertical structure, import and export of the same caliber, and in the same center line, the same as the valve installed in the piping into, compact appearance, small footprint, low building into, such as with a shield can be placed outdoors. 
 2, the impeller directly to security in the longer axis of the motor, short axial dimension, compact structure, reasonable configuration of pump and motor bearings can effectively balance the radial and axial loads of pump operation, thus ensuring the smooth operation of the pump vibration and noise is very low. 
 3, seal using a combination of mechanical seal or mechanical seal, seal ring imported titanium and medium-sized high-temperature mechanical seal and the use of carbide materials, wear-resistant sealing, can effectively increase the service life of mechanical seals. 
 4 Easy installation and maintenance, no need to open the pipeline system, just remove the pump conjoined seat nut to be pulled out all the rotor components. 
 5, according to the requirement that the flow and head need to use pumps in series and parallel operation mode. 
 6, according to the vertical and horizontal piping arrangements require the use of pump installation. 
 Main purposes: 
 1, the ISG vertical pipeline centrifugal pump for conveying water physical and chemical properties similar to water and other liquids used for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire boost, long-distance transport HVAC cycle, bathroom, heating and cooling cycle supercharged and equipment for temperature T <80 ° C. 
 IRG (GRG)-type vertical hot water (heat) circulation pump is widely applicable to: energy, metallurgy, chemical, textile, paper, as well as hotels, restaurants, and other boiler high temperature hot water booster pumps cycle transportation and urban heating system pumps, the IRG type using the temperature T <120 ° C, the GRG use temperature T <240 ° C. 
 IHG, vertical pipeline chemical pump for non-delivery of solid particles, corrosive, viscosity similar to water, liquid, apply to the petroleum, chemical, metallurgy, electric power, papermaking, food, pharmacy and synthetic fibers sector , the use of temperature -20 ℃ ~ 120 ℃. 
 4, YG vertical pipeline pump is used to transport gasoline, kerosene, diesel and other petroleum products, the transmission medium temperature -20 ℃ ~ 120 ℃. 
 Working conditions: 
 1, suction pressure ≤ 1.0MPa, or pump the maximum working pressure ≤ 1.6MPa, the pump inlet pressure + pump lift ≤ 1.6MPa pump hydrostatic test pressure of 2.5MPa, please specify when ordering the system working pressure. The pump system working pressure greater than 1.6MPa should be raised when ordering. Cast steel in order to manufacture the pump flow department and the connection part. 
 2, the ambient temperature T <40 ° C, relative humidity 0.2mm. 
 Note: If the use of media with small particles, when ordering, so that manufacturers use wear-type mechanical seal.
