Stainless Steel Submersible Sewage Pump 45KW 440V 60Hz for High-Flow Wastewater

The 200WQP250-32-45KW-4 is a high-flow stainless steel submersible sewage pump designed for wastewater drainage and fluid transfer applications. This pump features a rated flow of 250 m³/h, a rated head of 32 m, and a 45 kW motor. Configured for 440V, 60Hz power supply, it is ideal for projects using 440V 60Hz industrial power systems.

Constructed from stainless steel with a submersible design, this pump can be installed directly in sewage tanks, collection pits, sumps, or other drainage locations where submerged pumping is required.

• High-Flow Wastewater Pumping: With a rated flow of 250 m³/h, this pump is designed for applications requiring high wastewater transfer capacity, suitable for large sewage tanks, collection pits, industrial drainage systems, and municipal wastewater projects.
• 32 m Rated Head: The rated head is 32 m. Actual operating head should be calculated based on static lift, pipeline length, pipe diameter, fittings, valves, outlet pressure, and other system resistance.
• Stainless Steel Construction: Provides improved corrosion resistance compared to standard carbon steel or cast iron configurations. Suitable for wastewater and industrial drainage applications where stainless steel construction is required. The exact stainless steel grade should be confirmed according to pumped liquid characteristics and project requirements.
• 440V 60Hz Power Supply: Configured for 440V and 60Hz operation. Users should confirm site voltage, frequency, phase configuration, and motor starting requirements to ensure compatibility with the electrical system.

• Industrial Wastewater
• Wastewater Treatment Plants
• Municipal Sewage Systems
• Construction and Engineering Drainage
• Large Sumps and Collection Pits

Selecting a submersible sewage pump should not be based on motor power alone. Follow these steps:

1. Determine Required Flow Rate: If the project requires approximately 250 m³/h, confirm whether this is the normal design flow or maximum required flow.
2. Calculate Actual Total Dynamic Head: The rated head is 32 m, but actual system requirements must include pipeline friction losses and static elevation.
3. Identify Pumped Liquid Characteristics: Include wastewater temperature, corrosiveness, solid content, and fibrous materials.
4. Confirm Power Supply: This model is configured for 440V 60Hz operation and should match available site power.
5. Confirm Installation Conditions: Include sump depth, discharge pipe arrangement, installation position, control system, and maintenance requirements.

1. Before installation, confirm that the pump, discharge pipeline, power cable, and control system meet project requirements.
2. The pump should be operated within recommended working conditions and should not run for extended periods under unsuitable liquid-level conditions.
3. For automatic drainage systems, use a suitable level control system to control pump starting and stopping according to required water level.
4. If wastewater contains high concentrations of solid particles, long fibers, or corrosive substances, provide detailed liquid information during selection to confirm appropriate hydraulic and material configuration.
