English Product Details
Product Name: Kaiquan DG6-25×2 Horizontal Multistage Boiler Feed PumpBrand: Shanghai Kaiquan Pump (Group) Co., Ltd.
Model: DG6-25×2
Product Overview
The DG6-25×2 horizontal multistage boiler feed pump is a single-suction, multistage, segmental centrifugal pump specifically designed for industrial boiler systems. It features high efficiency, stable operation, and long service life. Suitable for transporting clean water or liquids with similar physical and chemical properties at temperatures up to 80°C, it is widely used in small-to-medium boiler feed systems, mine drainage, and high-head water supply for factories and urban areas.Structural Features
- Multistage Segmental Design: Suction inlet is horizontal; discharge outlet is vertical upward. Head can be adjusted by adding or removing impeller stages.
- Precision Assembly Required: Impeller outlet must align precisely with diffuser inlet center to avoid performance loss.
- Durable Materials: Main wetted parts made of cast iron or stainless steel for corrosion and wear resistance.
- Sealing Options: Available with packing seal or mechanical seal to suit different operating conditions.
Performance Parameters
- Flow Rate Q: 6 m³/h
- Head H: 50 m (25 m per stage × 2 stages)
- Speed N: 2950 rpm
- Motor Power: 3 kW (subject to actual configuration)
- NPSHr: ≤ 3.5 m
- Medium Temperature: ≤ 80°C
- Inlet Pressure: ≤ 0.59 MPa
Applications
- Industrial boiler feed systems
- Mine drainage and dewatering
- High-head water supply for factories and cities
- High-pressure clean water transfer in chemical, papermaking, and metallurgical industries
Installation & Maintenance Tips
- Prime the pump and vent air before startup.
- Regularly check bearing temperature and seal leakage.
- Drain the pump if idle for extended periods to prevent freezing or corrosion.
