Features

1. The pump has a vertical structure, the inlet and outlet diameters are the same, and the seat is on the same centerline. It can be installed in the pipeline like a valve. The appearance is compact and beautiful, the floor space is small, and the construction investment is low. Can be used outdoors.

2. The impeller is directly installed on the extended shaft of the motor, with short axial dimensions and compact structure. 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 smooth operation of the pump. Low vibration and low noise.

3. The shaft seal adopts a mechanical seal or a combination of mechanical seals, an imported titanium seal ring, a medium-sized high-temperature resistant mechanical seal, and a hard alloy material, a wear-resistant seal, which can effectively extend the life of the mechanical seal.

4. Convenient installation and maintenance, no need to disassemble the piping system, just remove the pump joint seat nut to pull out all the rotor parts.

5. According to the requirements of use, that is, the needs of flow and head, the pump can be used in series and related operation mode.

6. The vertical and horizontal installation of the pump can be adopted according to the requirements of pipeline layout.


product description

ISG, ISW series single-stage single-stage pipeline centrifugal pumps are scientific and technical personnel of the unit. The United Nations internal water pump experts choose excellent domestic hydraulic models, use the performance parameters of IS-type centrifugal pumps, and design cleverly on the basis of general vertical pumps. It is based on the different temperature and medium, and is based on the ISG and ISW type. It is suitable for hot water, high temperature, corrosive chemical pumps and oil pumps. This series of products have the advantages of high efficiency and energy saving, low noise and reliable performance.


The main purpose

1. ISG vertical pipeline centrifugal pump is used to transport clean water and other liquids with similar physical and chemical properties to clean water. It is suitable for industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, fire pressurization, and long-distance transportation. , HVAC refrigeration cycle, bathroom and other hot and cold water circulation pressurization and equipment supporting, the use temperature D <80 ° C

2. IRG vertical hot water (high temperature) circulating pumps are widely used in: energy, metallurgy, chemical, textile, paper, and hotels such as boilers, high temperature hot water pressurized circulation delivery and urban heating system circulation pumps, RG type Use temperature T <120 ° C, IRG type use temperature T <240 ° C.

3. ISGH vertical pipeline chemical pump is used to transport liquids without solid particles, corrosive, and viscosity similar to water. It is suitable for petroleum, chemical, metallurgy, power, paper, food and pharmaceutical and synthetic fiber departments. -20 ° C ~ 120 ° C

4. ISGB type vertical pipeline oil pump is used to transport gasoline, kerosene, diesel and other oil products. The temperature of the medium to be transported is -20 ° C ~ + 120 ° C.


Working conditions

1. Suction pressure ≤ 1.0MPa, or the maximum working pressure of the pump system ≤ 1.6MPa, that is, pump suction port pressure + pump head s ≤ 1.6MPa, pump static pressure test pressure is 2.5MPa, please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6M Pa, it should be put forward separately when ordering, so that the overflow part and the connection part of the pump are made of cast steel during manufacture.

2. Ambient temperature <40 ^, relative temperature <95%.

3. The volume content of solid particles in the conveyed medium does not exceed 0.1% per unit volume, and the particle size is <0.2 mm.

Note: If the medium used is with fine particles, please specify when ordering so that manufacturers can use wear-resistant mechanical seal
