**ISG Vertical Centrifugal Inline Fresh Water Pump**
The ISG series vertical centrifugal pumps are designed based on the unique pipe structure of centrifugal pumps and meet ISO 2858 standards. These pumps use advanced fluid models optimized by pump experts, ensuring high efficiency and reliability. All performance parameters exceed or meet the latest national standard JB/T 53058-93. They have been certified by the National Machinery Industrial Department in 1993 for quality inspection. Some units and components have been exported to domestic and international markets, receiving positive feedback from both local and overseas clients.
**Structure Explanation:**
As shown in the structure diagram, the pump consists of an electric motor and a pump unit that includes the pump body, impeller, pump cover, and mechanical seal. It is a single-stage, single-suction, vertical centrifugal pump with inlet and outlet at the same horizontal line and diameter. This design allows it to be easily mounted anywhere along a pipeline, occupying minimal space. The pump has a foot for added stability and flanges for the inlet and outlet, enabling the installation of a pressure gauge to ensure long-lasting operation within rated performance.
**Working Conditions:**
1. The maximum working pressure of the pump system is 1.6 MPa, meaning the inlet pressure plus the pump head should not exceed this value. The working pressure can go up to 2.5 MPa, but the inlet pressure must not exceed 0.3 MPa. If the inlet pressure exceeds 0.3 MPa, a balance hole seal should be used to maintain shaft force equilibrium.
2. The pump is suitable for liquids with solid particles not exceeding 0.1% by volume and particle size less than 0.2 mm. For liquids containing small particles, a durable mechanical seal is recommended.
3. The environmental temperature should be below 40°C, and relative humidity should not exceed 95%.
**Main Applications:**
1. The ISG vertical centrifugal pump is ideal for pumping clear water and similar liquids with temperatures not exceeding 80°C. It is widely used in industrial and municipal water supply and drainage systems, building pressurization, garden irrigation, fire protection systems, long-distance water supply, heating, bathroom applications, and cooling/warming water recycling.
2. The IRG vertical hot water pump is suitable for energy, refining, wood processing, chemical, textile, papermaking, restaurant, and hotel industries, as well as hot water recycling in boilers and city heating systems. It can handle liquids with temperatures up to 120°C.
3. The IHG series vertical pipeline chemical pump is designed for transporting non-corrosive, viscous liquids similar to water. It is commonly used in petroleum, chemical, metallurgy, power generation, papermaking, food, pharmaceuticals, and synthetic fiber industries, operating within a temperature range of -20°C to 120°C.
**Performance & Advantages:**
This pump offers high efficiency, energy savings, and a compact tubular design that simplifies installation. It features an integrated electro-mechanical design, saving space and making maintenance easy—just remove the pump bonnet nut and take out the motor and actuator unit. Its wide application scope makes it suitable for various industries.
**Range of Application:**
Ideal for daily and fire water supply in buildings, air conditioning systems, and pressurization of cold and hot clean media in various applications.
**Technical Parameters:**
- Flow: 6.3–1600 m³/h
- Head: 5–150 m
- Rotational Speed: 980–2900 r/min
- Diameter: Φ15–Φ500 mm
- Temperature: 0–120°C
- Working Pressure: ≤ 1.6 MPa
**Features:**
1. The ISG series single-stage, single-suction pipeline centrifugal pump is designed by domestic pump experts using advanced hydraulic models, meeting the performance standards of type IS vertical pumps.
2. The vertical structure allows for equal inlet and outlet diameters aligned on the same centerline, making it easy to install like a valve. The compact and aesthetically pleasing design reduces construction costs and occupies minimal space, allowing outdoor installation with protection.
3. The impeller is directly mounted on the motor shaft, resulting in a short axial dimension and a compact, well-balanced structure. This ensures smooth operation, low vibration, and minimal noise during pump operation.
