Need a powerful pump to remove dirty water and wastewater efficiently? The DV 750 Submersible Drainage Pump is designed to tackle demanding drainage jobs, from flooded areas and drainage pits to commercial and industrial wastewater applications.

Powered by a 0.75kW (1HP) motor, this submersible sewage pump delivers a maximum flow rate of 18,000 litres per hour (300 L/min) and a maximum head height of 12 metres.

Its combination of stainless steel and cast iron construction provides strength and resistance to wear, making it a practical choice for challenging drainage environments.

Designed to Handle Dirty Water and Wastewater

Not every water pump is suitable for moving wastewater containing dirt and debris.

The DV 750 Submersible Drainage Pump features a wide-passage design intended to help transfer dirty water containing suitable suspended solids and fibrous material.

This makes it useful for drainage applications where an ordinary clean-water pump may struggle.

Whether you're removing water from a drainage pit, transferring wastewater or clearing accumulated water from a flooded area, the DV 750 is designed to make the job easier.

Please Note: The exact maximum solids passage for this model should be confirmed before use, as different solids sizes are listed in the original product information.

Automatic Operation with Float Switch

The DV 750 comes fitted with a float switch that helps control pump operation automatically.

When the Water Level Rises

The float switch activates the pump when the water reaches the switching level.

When the Water Level Drops

The float switch switches the pump off when the water falls to the lower switching level.

This makes the pump particularly convenient for drainage pits, sumps and areas where water levels regularly change.

Durable Construction for Demanding Applications

The DV 750 combines stainless steel and cast iron components to provide a strong and sturdy design.

These materials offer good resistance to wear and corrosion in suitable operating environments.

The pump also features protection against overheating and excessive current, helping protect the motor during operation.

This combination makes it a practical option for wastewater drainage where durability and dependable performance are important.

Ideal Applications

  • Residential Wastewater Drainage – Remove dirty water from suitable household drainage systems.

  • Drainage Pits & Sumps – Automatically pump accumulated wastewater using the float switch.

  • Construction Site Drainage – Remove collected water containing compatible dirt and debris.

  • Commercial Drainage – Transfer wastewater from suitable commercial facilities.

  • Industrial Wastewater Removal – Assist with compatible factory and industrial drainage applications.

  • Floodwater Removal – Help clear accumulated dirty water from flooded areas.

  • Sewage Drainage Systems – Transfer compatible wastewater through suitable drainage installations.

  • Agricultural Drainage – Remove accumulated water from compatible agricultural drainage areas.

Understanding Flow Rate & Head Height

When choosing a drainage pump, it's important to understand how flow rate and head height affect performance.

Maximum Flow Rate – 18,000 L/h

This is the highest stated flow rate under low-resistance conditions.

Maximum Head Height – 12m

This is the maximum height the pump can lift water, at which the flow rate approaches zero.

As the pumping height increases, the available flow rate generally decreases.

Actual performance also depends on the pipe diameter, pipe length, bends and fittings used in your installation.

Please Note: The pump will not deliver its maximum flow rate at its maximum head height.

Installation & Important Information

  • Ensure the pump is correctly submerged during operation.

  • Do not exceed the maximum immersion depth of 5 metres.

  • The maximum liquid temperature must not exceed 40°C.

  • Only pump compatible liquids within the specified pH range of 4–10.

  • Allow enough space for the float switch to move freely.

  • Keep the pump inlet clear of oversized debris and obstructions.

  • Confirm the maximum solids passage before pumping wastewater containing large or fibrous materials.

  • Use suitable discharge piping and fittings.

  • Ensure all electrical connections are correctly installed and protected.

  • Regularly inspect and clean the pump to maintain efficient performance.

Important: Although the DV 750 is designed for dirty water and wastewater drainage, it is not necessarily suitable for every type of sewage or septic application. Always confirm that the liquid and solid materials being pumped are compatible with the pump.
