Product overview
Gardena 20000 BASIC 2-in-1 Submersible Dirty Water Pump 550W 20,000L/h 9m Head Stainless Steel
The Gardena 20000 BASIC 2-in-1 Submersible Dirty Water Pump is a high-capacity drainage pump designed for a range of clear and dirty water applications around the home and garden. With a 550W motor and maximum flow rate of up to 20,000 litres per hour, it provides efficient water removal from areas such as ponds, flooded spaces, cellars and other water-collection areas.
The 2-in-1 design allows the pump to be used with both clear water and dirty water. It can handle suspended particles of up to 35mm, making it suitable for applications where water contains larger debris or sediment.

For thorough drainage, the pump features a flat-suction mode capable of reducing residual water to approximately 1mm under suitable conditions. The float switch can be used for automatic operation, switching the pump on and off according to the water level. It can also be locked for manual operation when required.
The pump provides a maximum pressure of 0.9 bar and a maximum delivery head of 9 metres. It can be submerged to a depth of up to 7 metres and is designed for water temperatures of up to 35°C.
A stainless-steel shaft contributes to durability during regular pumping applications. The 10-metre power cable provides useful reach when positioning the pump, while the supplied connectors accommodate 25mm (1 inch) and 38mm (1½ inch) hose connections.
With its combination of high flow capacity, flexible clear/dirty water operation and automatic level control, this submersible pump is suitable for household drainage, garden maintenance and water management applications.
