Gravity pump Gardena 9036-20

The GARDENA Gravity Pump 9036-20 is a 750 W clear-water submersible pump with a maximum flow rate of 17,000 litres per hour and a maximum delivery height of 9 m (0.9 bar). Designed for drainage and water removal tasks, it features an Aquasensor system with digital LED touch controls for precise switch-on and switch-off heights and a flat suction capability down to 1 mm. The pump is built with a stainless steel cover, a ceramic-coated motor shaft and triple sealing with an oil chamber for reliable, leak-proof operation. It accepts hoses with diameters 32 mm (1 1/4"), 38 mm (1 1/2") and 50 mm (2") and also offers a G1 1/2" threaded connection for additional options.

Advantages

The integrated Aquasensor enables automatic operation in narrow shafts and allows adjustment of the start and stop water levels via touch control and LED indicators. The pump delivers high performance with low energy consumption, providing flat suction to 1 mm for near-dry results. Durable materials and triple sealing ensure long service life and safe, leak-free operation. Flexible hose connection options and a 10 m cable increase installation versatility.

How to use

Place the pump in the water to be removed ensuring stable positioning; use the flow boost feet if higher flow and reduced flat suction are required. Set the Aquasensor start and stop levels via the touch controls and confirm the LED display reading. Connect a suitable hose to the selected hose connection or the G1 1/2" thread, plug the pump into an appropriate AC power source and switch on. Monitor operation to ensure the pump runs within intended water levels and avoid running the pump beyond the recommended operating conditions.

Recommendations

Use the Aquasensor to prevent dry-running by programming the minimum switch-on level; choose the appropriate hose diameter for required flow and avoid pumping heavily contaminated water or solids to maintain pump life. Regularly inspect the seals and housing and store the pump dry and clean when not in use.
