Description
WQD450-35-75KW Multistage Bottom Suction Submersible Sewage Pump
The WQD450-35-75KW Multistage Bottom Suction Submersible Sewage Pump is a high-flow submersible sewage pump designed for municipal wastewater drainage, industrial wastewater transfer, mining drainage, construction dewatering, underground drainage and large-scale water discharge systems.
With a rated flow of approximately 450 m³/h, a rated head of approximately 35 meters, and a 75 kW submersible motor, this pump is designed for applications requiring high-volume wastewater transfer and stable drainage performance.
The WQD series adopts a bottom suction design, with the inlet positioned at the lower part of the pump. This configuration is suitable for sump pits, wastewater tanks, construction pits and other applications where the liquid level needs to be reduced as much as practical.

Key Features
450 m³/h High Flow Capacity
The WQD450-35-75KW is designed for high-volume drainage applications, with a rated flow of approximately 450 m³/h.
Typical applications include:
  • Municipal wastewater drainage
  • Industrial wastewater transfer
  • Mining drainage
  • Construction dewatering
  • Underground drainage
  • Wastewater tank drainage
  • Sump drainage
  • Large-scale water drainage projects
35 m Head
The rated head of the WQD450-35-75KW is approximately 35 meters, making it suitable for high-flow, medium-head drainage applications.
The required pump head should not be determined only by the vertical lifting height. The total system head normally includes:
Total Head = Vertical Lift + Pipeline Friction Loss + Local Losses + Required Outlet Pressure
Bottom Suction Design
The bottom suction design allows the pump to draw wastewater from the lower part of the sump or tank.
This configuration is particularly useful for:
  • Sump pits
  • Wastewater tanks
  • Construction pits
  • Underground projects
  • Temporary dewatering
  • Low-level drainage applications
Multistage Centrifugal Design
The WQD450-35-75KW uses a multistage centrifugal pump structure. Multiple impellers work progressively to increase the pressure of the pumped liquid.
The multistage design is suitable for applications requiring a combination of:
High Flow + Medium Head
75 kW Heavy-Duty Submersible Motor
The pump is equipped with a 75 kW submersible motor, suitable for large drainage systems and continuous-duty applications.
Motor configurations can be selected according to the customer's electrical system and project requirements, including:
  • Voltage
  • Frequency
  • Phase
  • Insulation Class
  • Protection Class
  • Cable Length
  • Starting Method
  • VFD Operation
Applications
Municipal Wastewater Drainage
The pump can be used in municipal wastewater tanks, sump pits, sewage pumping stations and other wastewater drainage systems.
Industrial Wastewater
The WQD450-35-75KW can be used for transferring industrial wastewater and process drainage liquids compatible with the pump materials.
Typical applications include:
  • Factory drainage
  • Industrial wastewater transfer
  • Wastewater treatment plants
  • Production wastewater discharge
  • Industrial collection tanks
Mining Drainage
The pump can be used for high-volume drainage in mines, mining pits and mine water collection areas.
Construction Dewatering
The bottom suction configuration is suitable for construction pits, underground projects, tunnels and other temporary dewatering applications.
Underground Drainage
The pump can be used in underground parking areas, underground facilities, tunnels and other low-lying drainage systems.
How to Select a Submersible Sewage Pump
Before selecting the WQD450-35-75KW, customers should provide the following operating information.
Required Flow Rate
For example: 450 m³/h
The flow rate determines the volume of wastewater that the pump needs to transfer per hour.
Required Head
For example: 35 m
The required head should be calculated according to the actual vertical lift, pipeline losses and outlet pressure.
Wastewater Characteristics
Please provide information about:
  • Liquid temperature
  • Solid particle concentration
  • Maximum particle size
  • Sand content
  • Corrosiveness
  • pH value
  • Liquid density
Sump or Tank Dimensions
Please provide:
  • Sump dimensions
  • Tank depth
  • Minimum liquid level
  • Maximum liquid level
  • Available pump installation space
Pipeline Conditions
The following information is recommended:
  • Discharge pipe diameter
  • Total pipeline length
  • Vertical lifting height
  • Number of elbows
  • Number of valves
  • Required outlet pressure
Installation Considerations
Before installing the WQD450-35-75KW submersible sewage pump, confirm the pump dimensions, installation space and inlet conditions.
During installation:
  • Ensure the pump operates under the specified submersible conditions
  • Avoid prolonged dry running
  • Confirm that the discharge pipeline can withstand the operating pressure
  • Select an appropriate cable for the 75 kW motor
  • Install suitable overload protection
  • Provide phase-loss and short-circuit protection
  • Check the motor rotation direction before initial operation
  • Confirm that solid particles do not exceed the allowable range
For a large 75 kW submersible sewage pump, electrical installation and commissioning should be performed by qualified personnel.
Frequently Asked Questions
What is the flow rate of the WQD450-35-75KW pump?
The rated flow is approximately 450 m³/h. Actual flow depends on the complete system operating point.
What is the head of the WQD450-35-75KW sewage pump?
The rated head is approximately 35 meters. Actual operating head should be calculated according to vertical lift, pipeline losses and outlet pressure.
What motor power does this pump use?
The WQD450-35-75KW is equipped with a 75 kW submersible motor.
What is a bottom suction submersible sewage pump?
A bottom suction submersible sewage pump draws the pumped medium through an inlet located at the lower part of the pump. This design is suitable for sump pits, wastewater tanks, construction pits and applications where a low residual liquid level is required.
Can this pump handle wastewater containing solid particles?
It can be configured for specific wastewater conditions, but the maximum solid particle size, concentration and medium characteristics should be provided before final selection. For wastewater containing high concentrations of abrasive sand, gravel or slurry, a dedicated wear-resistant pump should be considered.
Can the voltage and frequency be customized?
Yes. The motor can be configured according to the customer's local power supply. When requesting a quotation, please provide: Voltage + Frequency + Phase
For example: 380V / 50Hz / 3 Phase
How can I confirm whether the WQD450-35-75KW is suitable for my project?
Please provide: Required Flow + Required Head + Medium + Solid Particle Size + Pipeline Length + Vertical Lift + Voltage/Frequency
Our technical team can then evaluate the suitable pump configuration.
