The flow range of ISG vertical pipeline centrifugal pumps is from 1.5 to 1200 m3/h, and the head range is from 8 to 150 m. There are more than 250 specifications, including basic types, flow - expanded types, and A, B, C cutting types. According to different fluid media and temperatures, IRG type hot water pipeline pumps, IHG type chemical pumps, YG oil pumps, and IHGB type explosion - proof chemical pumps with the same performance parameters have been designed and manufactured.

The selection of ISG pipeline pumps should be based on the temperature and medium:

1. The ISG vertical pipeline centrifugal pump is used for transporting 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, pressurized water supply for high - rise buildings, garden sprinkler irrigation, fire - fighting pressurization, long - distance transportation, heating, ventilation and refrigeration circulation, cold and hot water circulation pressurization in bathrooms, and equipment matching. The operating temperature T < 80°C.

2. The IRG hot water pipeline centrifugal pump is suitable for the pressurized circulation and transportation of high - temperature hot water in boilers in industries such as metallurgy, chemical engineering, textile, wood processing, papermaking, as well as in hotels, bathrooms, and guesthouses, and for the heating circulation of urban housing. The operating temperature is below 120°C.

3. The GRG high - temperature pipeline centrifugal pump is widely used for the pressurized circulation and transportation of high - temperature hot water in boilers in industries such as energy, metallurgy, chemical engineering, textile, papermaking, as well as in hotels, bathrooms, and guesthouses, and for the heating circulation of urban housing. The operating temperature is below 240°C.

4. The IHG vertical stainless - steel pipeline centrifugal pump is used for transporting corrosive liquids without solid particles and with a viscosity similar to that of water. It is suitable for sectors such as petroleum, chemical engineering, metallurgy, electric power, papermaking, food and pharmaceutical, and synthetic fiber. The operating temperature ranges from - 20°C to 120°C.

5. The YG pipeline explosion - proof oil pump is used for transporting petroleum products such as gasoline, kerosene, and diesel. The temperature of the transported medium ranges from - 20°C to + 120°C.

6. The IHGB stainless - steel explosion - proof pipeline pump is suitable for transporting flammable chemical liquids.

7. The ISGD, IRGD, GRGD, IHGH, YGD, and IHGBD type vertical low - speed pipeline centrifugal pumps are suitable for occasions with very low environmental noise requirements and air - conditioning circulation.

Unique features of ISG pipeline pumps:

1. The ISG vertical pipeline centrifugal pump has a compact structure, small size, and beautiful appearance. Its vertical structure has a relatively low center of gravity, which coincides with the center of the pump feet, enhancing the operational stability and service life of the pump.

2. It is easy to install. The inlet and outlet diameters are the same and on the same center - line, allowing it to be directly installed at any position on the pipeline like a valve. The motor can be used outdoors with a rain - proof cover. The ISG vertical pipeline centrifugal pump is equipped with mounting feet for stable installation.

3. It runs smoothly, with low noise and high concentricity of components. The motor uses low - noise bearings and is equipped with a non - stop oiling device. The pump impeller has excellent dynamic and static balance, runs without vibration, and improves the usage environment.

4. There is no leakage. The shaft seal uses a corrosion - resistant and wear - resistant hard - alloy mechanical seal, which solves the problem of serious leakage of the centrifugal pump packing, prolongs the service life, and ensures a clean and tidy operating site.

5. It is easy to maintain. There is no need to disassemble the pipeline. Just remove the pump cover nuts and take out the motor and transmission components for maintenance.

6. According to on - site usage conditions, the pump can be installed vertically, horizontally, or in multiple ways. According to the requirements of flow and head, parallel or series methods can be used to increase the required flow and head.

What are the usage requirements for ISG pipeline pumps?

1. The suction pressure of the ISG pipeline pump ≤ 1.0 Mpa, or the maximum working pressure of the pump system ≤ 1.6 Mpa, that is, the pump suction port pressure + pump head ≤ 1.6 Mpa. The hydrostatic test pressure of the pump is 2.5 Mpa. Please indicate the system working pressure when placing an order. If the working pressure of the pump system is greater than 1.6 Mpa, please specify it separately when placing an order so that cast - steel materials can be used for the flow - through parts and connection parts of the pump during manufacturing.

2. The ambient temperature < 40°C, and the relative humidity < 95%.

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

Note: If the medium used contains fine particles, please indicate it when placing an order so that a wear - resistant mechanical seal can be used.
