The **QD (G) type high head seawater pump** is a horizontal multi-stage centrifugal pump designed for the efficient transportation of seawater and other liquids with physical and chemical properties similar to pure water. It is ideal for applications involving seawater, corrosive water, rainwater, and marine environments.
This pump is especially suitable for use in coal industries, where durability and performance under harsh conditions are essential. Its construction allows it to handle fluids with less than 1% foreign matter content and particle sizes up to 0.1mm.

### **Construction Options**
- **Impeller:** The core component of the multistage pump, available as a closed impeller. Smooth inner and outer surfaces reduce flow friction and enhance efficiency, especially at high pressures.
- **Casing:** Acts as the main body of the pump, providing structural support and connecting to the bearing bracket.
- **Pump Shaft:** Transfers mechanical energy from the motor to the impeller.
- **Shaft Bearing:** Available in rolling or sliding types. Rolling bearings use grease, while sliding bearings use transparent oil as lubricant.
- **Sealing Ring:** Reduces internal leakage by increasing back-flow resistance, thereby extending the life of the impeller and casing.
- **Stuffing Box:** Composed of packing, seal ring, tube, gland, and sealing tube to maintain vacuum during operation.
