📊 Basic Information

📦 Packaging & Delivery

⚙️ Product Description

LG Vertical Multi-stage Centrifugal Pump is a new generation product developed according to the standards for water supply and drainage in high-rise buildings and Chinese fire standards. Due to the adoption of an efficient and energy-saving superior hydraulic model, this type of pump has the advantages of high efficiency and a wide range of performance. Moreover, the model is optimized with a more rational distribution, which can better meet the fire protection needs of different floors and Pipe Resistance.

💧 Working Conditions

• Media: Clean water or non-corrosive media with solid insoluble content < 0.1% of unit volume.
• Medium Temperature Range: -15ºC to +95ºC.
• Maximum System Working Pressure: ≤2.5MPa.
• Ambient Environment: Temperature < 40ºC, Relative Humidity < 95%.

🌟 Product Advantages

• Compact Design: Small volume and takes up less installation space.
• Maintenance Friendly: Easy to dismantle wearing parts (mechanical seal) without disassembling the motor.
• Easy Repair: No adjustment required for assembly; simple inspection and repair process.
• Hydraulic Balance: Radial and axial forces are balanced hydraulically combined with bearing support.
• Hot Water Capability: Uses specialized hot water type mechanical seals.

🏢 Applications

• Water supply in high-rise construction firefighting systems.
• Industrial and municipal water supply and drainage.
• Garden sprinkler systems.
• Long-distance water transportation.
• Water supply for air conditioning and heating systems.

📐 Structural Design

1. Vertical multi-stage segmental structure, tightly bolted together by inlet, middle, and outlet sections. Each stage features an impeller and guide vane.
2. Shaft seal uses a specially designed mechanical seal that can be replaced by removing the intermediate clamshell coupling without dismantling the motor.
3. Compatible with standard IE2/IE3/IE4 series B5 type motors (380V, 50HZ, 2900 rpm).
4. Flexible port positions: Suction at bottom, discharge at top. Port angles can be adjusted to 0°, 90°, 180°, or 270° (standard is 180°).
