Gardena 20000 Basic Clear Water Submersible Pump, 550 W, 20,000 l/h, 9 m, Black

The GARDENA Clear Water Submersible Pump 20000 BASIC handles the drainage of clear water from cellars, tanks, and pools. Running on a standard AC mains supply, it provides a reliable solution for residential water removal. A 550 W motor drives a maximum flow rate of 20,000 litres per hour, paired with a 9 m maximum delivery head for the vertical lift needed to move water out of deep basements. The unit pumps down to a 1 mm residual level, leaving flat surfaces nearly dry.

The housing is stainless steel to resist corrosion during continuous underwater use. The unit weighs 4.7 kg and includes an integrated carrying handle for easy transportation and positioning. A 10-metre H05 RNF power cable allows flexible placement away from the nearest mains outlet. Built-in overload protection shuts the motor down automatically if internal temperatures rise too far. An adjustable float switch manages start and stop based on the water level and prevents dry running. The device is rated for both indoor and outdoor use.

• IP X8 waterproof rating – ensures safe, continuous operation while fully submerged.
• Maximum immersion depth of 7 m – allows placement at the bottom of deep pools or large rainwater tanks.
• Maximum operating pressure of 0.9 bar – provides steady force for pushing extracted water through connected hoses.
• Maximum input water temperature of 35 °C – safely handles standard ambient and moderately warm water sources.
• Integrated on/off switch – allows direct manual control when automatic float operation is not needed.
