Stainless Steel Submersible Sewage Pump with 80 m³/h Flow and 10 m Head for Wastewater Drainage

The 100WQ80-10-4kW stainless steel submersible sewage pump is engineered for wastewater transfer, sewage discharge, drainage, and dewatering applications. With a rated flow of 80 m³/h, rated head of 10 m, and motor power of 4 kW, this pump features a DN100 nominal discharge diameter.

The integrated pump and motor design operates directly within the pumped liquid, while stainless steel construction ensures corrosion resistance in wet environments and wastewater applications. Ideal for municipal drainage, industrial wastewater handling, building drainage, and agricultural water removal.

Voltage, frequency, stainless steel grade, cable length, and installation accessories can be selected according to operating conditions.

The 100WQ80-10-4kW submersible sewage pump consists of a submersible motor, pump casing, impeller, shaft, mechanical seal, power cable, and discharge connection.

When the motor starts, it drives the impeller to rotate inside the pump casing. Wastewater enters through the pump inlet and gains velocity and pressure through the impeller. The liquid is then discharged through the DN100 outlet and connected pipeline.

Since the pump operates below the liquid level, no separate suction pipe or priming system is required. This design saves installation space and eliminates problems associated with insufficient suction lift.

• 80 m³/h Drainage Capacity: Suitable for medium-volume drainage applications including collection pits, wastewater tanks, industrial sites, and underground spaces.
• 10 m Rated Head: Ideal for high-flow, low-head applications such as short-distance wastewater transfer, basement drainage, and floodwater removal.
• Stainless Steel Construction: Corrosion-resistant wetted components with optional 304, 316, or 316L stainless steel grades based on liquid composition, chloride concentration, temperature, and corrosion level.
• Compact Submersible Design: Installs directly inside sewage tanks or collection pits, reducing need for additional ground-level equipment. Available in mobile, fixed flange, and automatic coupling installations.
• Mechanical Seal Protection: Separates pumped liquid from motor chamber. Proper installation, suitable operating conditions, and regular maintenance extend sealing component service life.
• Flexible Control Options: Compatible with control panels and float level switches for automatic operation. Optional protection functions include overload, phase-loss, short-circuit, and abnormal-voltage protection.

Before selecting a submersible sewage pump, confirm the following operating information:

1. Required flow rate and total dynamic head
2. Liquid composition, temperature and pH value
3. Type and maximum diameter of solid particles
4. Concentration of suspended solids or fibres
5. Site voltage, frequency and phase
6. Sewage tank depth and pipeline length
7. Number of pipe bends, valves and fittings
8. Required installation method
9. Control-panel and liquid-level control requirements

• 304, 316 or 316L stainless steel construction
• Customized power cable length
• Automatic coupling system
• Guide rails and lifting chain
• Float level switches
• Sewage pump control panel
• Motor overload and phase-loss protection
• Dual-pump alternating control system
• Customized voltage
• 50 Hz or 60 Hz motor

Before installation, inspect the power cable, mechanical seal, fasteners, and pump casing. Confirm that the power supply matches motor specifications and check the motor's rotation direction.

Use a lifting chain or suitable lifting device to lower the pump into the sewage tank. Do not lift or pull the pump by its power cable.

The pump should not run dry for extended periods. Regularly inspect and clean the inlet to prevent plastic bags, fibres, and large debris from blocking the impeller. If wastewater contains long fibres, easily tangled materials, or large solids, confirm the impeller design and maximum solids passage before ordering.

"100" represents a 100 mm discharge diameter. "WQ" identifies a submersible sewage pump. "80" indicates a rated flow of 80 m³/h, "10" indicates a rated head of 10 m, and "4kW" is the motor power.

Yes. It can handle wastewater containing suspended solids and certain solid particles. The maximum solids passage depends on the impeller and internal flow-channel design and should be confirmed before ordering.

Yes. The pump can be manufactured with 304, 316, or 316L stainless steel components. Material selection should be based on the liquid's chemical composition, chloride concentration, and operating temperature.

Yes. Float switches and a control panel can automatically start and stop the pump according to the liquid level. High-level alarms and motor protection functions can also be added.

Yes. Both 50 Hz and 60 Hz configurations are available. Please provide the required voltage, frequency, and phase when requesting a quotation.
