**Company Information:**
Shijiazhuang An Pump Machinery is a leading manufacturer of centrifugal pumps, specializing in diesel water pumps, multi-stage pumps, high-pressure pumps, boiler feed pumps, and various types of industrial centrifugal pumps.
**1. Industrial Electric Horizontal High-Pressure Water Boosting Multi-Stage Pump Introduction:**
The QD and QDG series are horizontal boiler feed water pumps and high-pressure multi-stage pumps. These pumps are designed with multiple single-stage impellers combined to achieve high head. They are suitable for clean water or liquids with less than 1% concentration and particles smaller than 0.1mm, or liquids similar to water in physicochemical properties. 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.
We use different materials such as HT200, QT500, ZG500, and stainless steel depending on the application. Key features include:
- Easy installation and mobility
- Pump body supported by anchors for structural stability
- No overload design for stable performance
- National standard hydraulic model for high efficiency and anti-cavitation performance
- Available packing seal or mechanical seal
**2. Application Scope:**
Suitable for mining, municipal water supply and sewage projects, boiler feed systems, chemical transfer, and more. It can handle non-corrosive and corrosive liquids, oil, and petroleum products under specific conditions.
**3. Applications Include:**
- Air-conditioning systems
- Cooling systems
- Industrial cleaning
- Water treatment and purification
- Aquaculture
- Fertilizing/metering systems
- Environmental applications
