SG, IRG, GRG, IHG, YG, and TEB series single-energy, single-suction vertical pipeline centrifugal pumps are designed based on the performance parameters and hydraulic models of IS-type pumps. These pumps are compact in design, with identical inlet and outlet diameters aligned on the same horizontal line. The shaft sealing system utilizes high-quality mechanical seals. The TEB model is a newly developed product by our factory, specifically tailored to address space constraints and lifting equipment limitations during pump maintenance.
1. **ISG Type Pipeline Pump**: Ideal for hot and cold water circulation in heating and air conditioning systems, high-rise building water supply, fire-fighting pressurization, long-distance water delivery, and industrial process pressurization. It is suitable for clear water or similar non-corrosive liquids with a temperature not exceeding 80°C.
2. **IRG Type Hot Water Pipeline Pump**: Primarily used for hot and cold water circulation in greenhouses, boilers, and bathrooms, as well as non-corrosive hot water pressurization in various industries. The medium temperature should not exceed 150°C.
3. **GRG Type High-Temperature Pipeline Pump**: Designed for conveying non-corrosive high-temperature liquids in boiler water supply and drainage cycles, heating systems, and other industrial applications. The operating temperature of the medium is limited to 200°C.
4. **IHG Chemical Pipeline Pump**: Used for pressurizing and transferring corrosive chemical liquids in industries such as chemicals, environmental protection, pharmaceuticals, papermaking, and textiles. The medium temperature should not exceed 100°C.
5. **YG Type Pipeline Oil Pump**: Suitable for transporting non-corrosive oils and petroleum products without solid particles, with a viscosity below 120 centistokes. The operating temperature range is from -20°C to 80°C.
6. **TEB Split-Type Vertical Pipeline Pump**: A versatile option that can be adapted for various working environments by changing the material composition.
**Performance Range**
- Flow Rate: 5.6 to 720 m³/h
- Head: 5 to 125 meters
- Maximum Working Pressure: 1.6 MPa (for sizes up to 200 mm), 1.0 MPa (for sizes over 200 mm)
- Inlet Pressure ≤ 0.3 MPa (note when exceeding this value)
These pumps feature the same inlet and outlet diameter, with the discharge port aligned horizontally at 180°. Key components include the pump body, pump cover, impeller, seal ring, motor bracket, and more. The pump and motor are coaxial (except for the TEB type, which uses an independent pump shaft). The shaft seal is made of premium mechanical seals. From the motor side, the pump rotates clockwise.
**Materials Available**: Cast iron, cast steel, and cast stainless steel.
