GARDENA 20000 BASIC Submersible Dirty Water Pump, 550 w, 20000 l/h, 9 m, 35 mm

The GARDENA 20000 BASIC Submersible Dirty Water Pump is designed for dirty-water drainage tasks. It runs from a standard AC power source and provides a practical way to clear flooded areas or empty garden ponds. The pump draws 550 W, giving it enough power for steady operation under continuous loads. It delivers a flow rate of 20,000 l/h, so large volumes of liquid can be moved quickly. For vertical lift, it reaches a maximum delivery head of 9 m, allowing water to be pushed from basements or sunken pits up to a higher discharge point.

The housing is made of stainless steel, which resists corrosion during prolonged exposure to moisture. The unit weighs 4.8 kg, making it manageable for one person to carry and position. A 10-metre H05 RNF power cable is integrated into the pump, providing ample reach from a nearby outlet. The pump is fully rated for outdoor use and withstands typical exterior conditions without additional protective covering. It handles liquid temperatures up to 35 °C safely. These design choices keep the hardware stable during demanding drainage sessions.

• Maximum particle size of 35 mm – handles suspended dirt and debris without clogging the internal mechanics.
• IPX8 waterproof rating – protects the unit against continuous submersion in deep water.
• Maximum operating pressure of 0.9 bar – provides sufficient force to maintain steady flow through connected hoses.
• Maximum immersion depth of 7 m – allows placement at the bottom of deep flooded areas or large tanks.
• Maximum suction height of 7 m – draws liquid upward efficiently from steep depressions before discharging it.
