Water Pump Gardena 9034-20 450 W 0.7 bar 11000 l/h

The GARDENA Clear Water Pump 11000 Aquasensor is a submersible pump designed for efficient removal of clear or slightly contaminated water. With a 450 W motor and a maximum flow rate of up to 11,000 litres per hour, it delivers strong performance while offering precise electronic level control via the Aquasensor. The pump supports flat suction to 1 mm and can be used for tasks such as emptying basements, rainwater barrels or pools.

Advantages

The integrated Aquasensor measures water level without direct contact and allows touch-controlled adjustment of switch-on and switch-off heights, preventing dry-running and enabling operation in narrow shafts. Durable materials including a stainless steel cover and a ceramic-coated motor shaft with triple sealing and oil chamber provide reliable protection and long service life. The pump features selectable flow boost feet for higher flow or flat suction as required and a straightforward GARDENA hose connection system compatible with 32 mm (1 1/4"), 38 mm (1 1/2") and 50 mm (2") hoses plus a G1 1/2" thread.

How to use

Place the pump in the water to be removed ensuring stable positioning; for flat suction, set the pump directly on the surface to be drained and remove the flow boost feet if necessary. Connect a suitable hose using the GARDENA hose connection system or the G1 1/2" thread. Use the Aquasensor touch controls to set the desired switch-on and switch-off water levels and, if required, set the timer. Start the pump and monitor the LED display for current water level and operating status. After use, disconnect power, empty remaining water and store the pump in a dry place.

Recommendations

Use the pump only for clear or slightly contaminated water and avoid pumping water with large solids or abrasive debris. Regularly check seals and hose connections and follow the manufacturer’s maintenance instructions to ensure long-term reliable operation.
