Product Overview
ISG vertical pipeline centrifugal pump , also known as piping , pumps, pipeline centrifugal , single-stage centrifugal pumps, vertical pumps , booster pumps, heat pumps, circulating pumps, etc. , I plant pumps Institute of Technology in the United Nations expert selection domestic excellent hydraulic model, using iS -type centrifugal pump performance parameters and SG -type pipeline pump , the ingenious combination on the basis of generally vertical pipeline pump design is made , while according to temperature, different media ISG series pipeline pump derived based on the application of hot water pipeline pumps, high temperature corrosion-resistant chemical pipeline pumps, piping pumps. This series of products with high efficiency , low noise, reliable performance . Comply with the latest Ministry of Machinery JB/T53058-93 standard requirements , design and manufacture according to the international ISO2858 standards.
Product Features
1, the pipeline centrifugal pump for the vertical structure , import and export of the same caliber , and is located in the same center line, like the valve installed in the pipeline , compact appearance , small footprint, construction investment is low , such as with protective cover can be placed outdoors .
2 , pipeline centrifugal impeller mounted directly on the long axis of the motor , short axial dimension , compact structure, reasonable allocation of pump and motor bearings , can effectively balance the radial and axial loads generated by operation of the pump , thus ensuring the pump smooth running, low vibration, low noise.
3 , pipeline centrifugal pump mechanical seal or seal with a combination of mechanical seals , sealing rings imported titanium alloy , medium and high temperature mechanical seal with carbide materials , wear-resistant seal , can effectively extend the service life of mechanical seals .
4 , pipeline pump installation and maintenance easy , no need to open the pipeline system , just remove the pump body seat nut out all the rotor parts.
5 , pipeline centrifugal pump flow and head requirements that need using series and parallel manner using the pump according to the requirement .
6 , pipeline centrifugal pump can adopt vertical and horizontal installation in accordance with requirements of piping layout .
The main purpose
1, ISG vertical pipeline pump for conveying water and physical and chemical properties similar to water or other liquids for industrial and urban water supply and drainage , high-rise building pressurized water , garden irrigation, fire booster , long-distance transport , HVAC refrigeration cycle, bathroom, heating and water circulation and equipment for pressurized , temperature T <80 ℃.
2, IRG (GRG) Vertical hot water ( heat) cycle pipeline pumps are widely used in: energy , metallurgy , chemicals, textiles , paper, and hotels and other high-temperature hot water boiler loop pressurized transport and urban heating system circulating pump , IRG -type temperature T <120 ℃, GRG type temperature T <240 ℃.
3, IHG vertical chemical centrifugal pump for conveying solid particles, corrosive , viscosity similar to water , suitable for petroleum, chemical, metallurgy , electric power , paper, food, pharmacy and synthetic fibers sectors , temperature is -20 ℃ ~ 120 ℃.
4, YG vertical pipeline centrifugal pumps for the transport of gasoline , kerosene , diesel and other petroleum products are transported medium temperature of -20 ℃ ~ +120 ℃.
Working conditions
1, the suction pressure ≤ 1.0MPa, the maximum working pressure or pump system ≤ 1.6MPa, namely pump inlet pressure + pump lift ≤ 1.6MPa, hydrostatic test pump pressure of 2.5MPa, please specify when ordering system working pressure . Pump system working pressure greater than 1.6MPa should be made at the time of ordering , in order to manufacture the pump flow part and a coupling portion using steel materials.
2 , ambient temperature <40 ℃, relative humidity <95 %.
3 , the transmission medium volume fraction of solid particles per unit volume of not more than 0.1% , a size of <0.2mm.
Note: If using a medium with small particles , please when ordering so that manufacturers use wear-resistant mechanical seal .
