**Company Information:**
Shijiazhuang An Pump Machinery is a leading manufacturer of centrifugal pumps, including diesel water pumps, multistage pumps, high-pressure pumps, boiler feed pumps, and more. With over two decades of experience in pump design and production, the company ensures high-quality products tailored to various industrial needs.
**1. Industrial Electric Horizontal High-Pressure Water Boosting Multistage Pump – Introduction:**
The QD and QDG series are horizontal boiler feed water pumps designed for high head applications. These multistage centrifugal pumps consist of multiple single-stage impellers connected together, allowing them to generate significant pressure. They are ideal for pumping pure water or liquids with less than 1% concentration and particles smaller than 0.1mm. The QD series operates at temperatures up to 80°C, while the QDG series can handle up to 150°C. Head ranges from 76m to 1080m, with flow rates between 3m³/h and 600m³/h.
Different materials such as HT200, QT500, ZG500, and stainless steel are used based on the medium being pumped.
**Key Features:**
- Easy installation and mobility
- Stable structure with anchor support
- No overload design for stable performance
- National standard hydraulic model for high efficiency and anti-cavitation performance
- Available with packing seal or mechanical seal
**2. Application Scope:**
Suitable for:
- Mining, municipal water supply, and sewage engineering
- Transfer of water-based liquids without solid particles, under 80°C
- Boiler feed systems or hot water-like media, under 105°C
- Corrosive liquid transfer, between -20°C and 105°C
- Oil and petroleum product transfer, between -20°C and 150°C, with viscosity under 120cSt
**3. Common Applications:**
- Air conditioning systems
- Cooling systems
- Industrial cleaning
- Water treatment and purification
- Aquaculture
- Fertilizer/metering systems
- Environmental projects
