The ISG series single-stage single-suction pipeline centrifugal pump is designed by our scientific and technical personnel and the domestic water pump experts to select domestic excellent hydraulic models, adopt the performance parameters of IS-type centrifugal pumps, and ingeniously combine and design on the basis of general vertical pumps. , At the same time, based on the ISG type, suitable hot water, high temperature, corrosive chemical pumps and oil pumps are derived according to the use temperature and medium. This series of products have the advantages of high efficiency, energy saving, low noise and reliable performance. It meets the requirements of the latest JB/T53058-93 of the National Ministry of Machinery. The products are designed and manufactured according to the international ISO2858 standard. Passed the unified inspection of pipeline pump products by the Ministry of Machinery Industry in 1993.
1. The pump is a vertical structure with the same inlet and outlet diameters and located on the same centerline. It can be installed in the pipeline like a valve. It has a compact and beautiful appearance, small footprint, and low construction investment. It can be installed if a protective cover is added. For outdoor use.
2. The impeller is directly mounted on the extended shaft of the motor. The axial size is short and the structure is compact. The pump and motor bearings are arranged reasonably, which can effectively balance the radial and axial loads generated by the pump operation, thereby ensuring the pump’s operational balance, vibration and noise Very low.
3. The shaft seal adopts mechanical seal or mechanical seal combination, adopts imported titanium alloy seal ring, medium-sized high temperature resistant mechanical seal and adopts hard alloy material, wear-resistant seal, which can effectively increase the service life of mechanical seal.
4. Easy installation and maintenance, no need to dismantle the piping system, just remove the pump joint base nut to draw out all the rotor parts.
5. The series and parallel operation modes of pumps can be adopted according to the requirements of use, that is, the needs of flow and head.
6. The vertical and pattern installation of the pump can be adopted according to the requirements of piping layout.
1. The ISG vertical pipeline centrifugal pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water delivery, garden sprinkler irrigation, fire pressurization, and long-distance transportation. , HVAC refrigeration cycle. For bathrooms and other hot and cold water circulation pressurization and equipment matching, the use temperature T<80℃.
2. IRG (GRG) vertical hot water (high temperature) circulating pump is widely used in: energy, metallurgy, chemical industry, textile, papermaking, and high-temperature hot water pressurized circulating pumps of boilers such as hotels and restaurants and urban heating systems. IRG type operating temperature T<120℃, GRG type operating temperature T<240℃.
3. IHG type vertical pipeline chemical pumps are used to transport liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. They are suitable for petroleum, chemical, metallurgical, electric power, paper, food, pharmaceutical and synthetic fiber sectors. It is -20℃～120℃.
4. YG type vertical pipeline oil pump is used to transport petroleum products such as gasoline, kerosene, diesel, etc. The temperature of the medium being transported is -20℃～+120℃.
1. Suction pressure ≤l.0MPa, or pump system maximum working pressure ≤1.6MPa, that is, pump suction port pressure + pump head ≤1.6MPa, pump static pressure test pressure is 2.5MPa, please indicate the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6MPa, it should be stated separately in the order. In order to use cast steel material for the flow part and connection part of the pump during manufacture.
2. When the ambient temperature is less than 40℃, the relative humidity is less than 95%.
3. The volume content of solid particles in the conveyed medium does not exceed 0.1% of the unit volume, and the particle size is >0.2mm.
Note: If the medium used is with fine particles, please specify when ordering so that the manufacturer can use wear-resistant mechanical seals.
