Shanghai and Shanghai Pump Manufacturing Co., Ltd. centrifugal pump

First, the product overview: ISG single-stage single suction vertical pipeline centrifugal pump is the unit of science and technology personnel within the United Nations pump expert selection of excellent hydraulic model, using IS centrifugal pump performance parameters, based on the general vertical pump Ingenious combination of design. At the same time according to the use of temperature, medium and other different on the basis of the ISG type sent hot water, high temperature, corrosive chemical pumps, pumps. The product has high efficiency, low noise, reliable performance and so on. Second, the product features: 1, ISG single-stage single suction vertical pipe centrifugal pump for the vertical structure, import and export of the same diameter, and located in the same centerline, can be installed in the pipeline as the valve, compact appearance, Small footprint, low construction investment, such as with the protective cover can be placed outdoors. 2, the impeller is mounted directly on the motor shaft, the axial size is short, compact structure, the pump and motor bearing configuration is reasonable, can effectively balance the pump radial and axial load, thus ensuring the smooth operation of the pump, Small vibration, low noise. 3, shaft seal mechanical seal or mechanical seal combination, the use of imported titanium alloy seal, medium-temperature mechanical seal and the use of hard alloy material, wear-resistant seal, can effectively extend the service life of mechanical seals. 4, easy installation and maintenance, without moving the pipe system, as long as you remove the pump seat nut can extract all the rotor components. 5, ISG single-stage single-suction vertical pipeline centrifugal pump can be used according to the requirements of the flow and lift the pump string, parallel operation. 6, ISG single-stage single-suction vertical pipe centrifugal pump can be used according to the requirements of the pipeline layout of the pump vertical and horizontal installation. Third, the main purposes: 1, ISG vertical pipeline centrifugal pump for the transport of water and physical and chemical properties similar to other liquids used for water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden sprinkler, fire by Pressure, long-distance transport, HVAC refrigeration cycle, bathroom and other heating and cooling water circulation and pressure equipment and equipment, the use of temperature T 2, IRG (GRG) vertical hot water circulation pump is widely used: energy, metallurgy, Textile, paper, and hotel boilers High-temperature hot water Boosting Circulation and urban heating systems Recycling pumps, IRG type Temperature T 3, IHG vertical pipeline chemical pump for conveying solid particles without corrosive Its viscosity is similar to that of water. It is suitable for petroleum, chemical industry, metallurgy, electric power, papermaking, foodstuff, pharmacy and synthetic fiber. Its working temperature is 20 ℃ ~ + 120 ℃. 4, YG vertical pipe pump for the transportation of petrol, kerosene, diesel and other petroleum products, the medium temperature is -20 ℃ ~ +120 ℃. Fourth, working conditions: 1, inhalation 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 of 2.5MPa, please indicate the system working pressure when ordering. Pump system operating pressure greater than 1.6MPa should be separately ordered when ordering, in order to manufacture the pump overcurrent part and the coupling part of the cast steel material. 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, so that manufacturers use wear-resistant mechanical seal . Fifth, the type of meaning: For example: ISG100-160 (I) AB ISG-vertical centrifugal pump 100-pump inlet and outlet diameter (mm) 160- nominal diameter of the impeller (mm) I- flow classification AB- impeller through the first and second Cutting ISG, IRG, IHG, YG pipeline centrifugal pump performance parameters (high speed 2900r / min):
