High Performance Tin Bronze Submersible Pump: 400QJH500-20-45KW for Demanding Working Conditions
400QJH500-20-45KW Submersible Pump
In industrial drainage, municipal wastewater treatment, agricultural irrigation, and other applications, a stable, reliable, and energy-efficient submersible pump is an essential piece of equipment for system operation. Today, we introduce the 400QJH500-20-45KW Submersible Sewage Pump, a high-performance pump designed to meet various engineering requirements through its materials, construction, technical specifications, and service support.
Core Parameters: Designed to Meet Application Requirements
The main performance parameters of this submersible pump are designed for high-flow and medium-head applications:
| Parameter | Value |
|---|---|
| Flow Rate | 500 m³/hr |
| Head | 20 m |
| Power | 45 KW |
| Voltage / Frequency | 3 Phase / 480V / 60Hz |
| Speed | 1750 RPM |
The pump can deliver 500 cubic meters of liquid per hour for large-scale drainage and water transfer projects. The 20-meter head is suitable for applications requiring vertical lifting and pipeline transportation.
Material Upgrade: Corrosion Resistance, Wear Resistance, and Longer Service Life
For corrosive media such as wastewater and seawater, key components are manufactured using special alloys and composite materials to reduce corrosion-related failures.
| Component | Material | Key Benefits |
|---|---|---|
| Pump Head, Impeller, and Valve Body | Tin Bronze | Resistant to seawater and mild acid or alkali corrosion; High mechanical strength; Helps prevent impeller deformation and pump head cracking |
| Motor Housing | Duplex Stainless Steel 2205 | Higher resistance to chloride corrosion than conventional 304 and 316 stainless steel; Suitable for coastal, marine, and chemical industry environments |
| Bearing | Composite Material | Provides wear resistance and self-lubricating performance, reducing friction loss |
| Wear Ring | Duplex Stainless Steel 2205 | Helps reduce leakage caused by shaft wear |
| Pump Shaft | Duplex Stainless Steel 2205 | Helps reduce leakage caused by shaft wear |
| Motor Rotor Shaft | Carbon Steel 45# welded with Duplex Stainless Steel 2205 | Provides both strength and corrosion resistance; Designed to prevent shaft failure during high-speed operation |
| Motor Winding | Cross-Linked Polyethylene (PE2 + PA) | Resistant to high temperature and moisture; Helps prevent winding short-circuit failures |
Optimized Details: Easier Installation and Maintenance
In addition to performance, the pump includes several practical design features to simplify installation and reduce maintenance costs.
- Discharge Outlet: Size: DN200 mm; Standard flange connection; Easy connection to existing pipeline systems
- Additional Flange: When the pump head includes a valve body, one additional Duplex Stainless Steel 2205 flange is supplied.
- Power Cable: Length: 5 meters; Includes grounding wire; Complies with safety requirements and reduces on-site wiring risks
- Sacrificial Anode Protection: Quantity: 2 pieces; Installed on the pump before shipment; Provides additional corrosion protection through the sacrificial anode principle; Helps extend overall pump service life
- Performance Test Report: Each pump is tested before shipment and supplied with a performance test report.
