Submersible Pump Gardena 1764-20 550 W 4700 l/h 7 m

The GARDENA Submersible Pump 1764-20 (550 W, 4700 l/h) is a high-performance pump designed for rainwater recycling and general water transfer tasks. Its stainless steel pump body and compact design allow insertion through narrow openings, while the two-stage hydraulic system provides strong pressure performance for applications with higher pressure requirements. The unit includes an adjustable telescopic pipe and an integrated fine mesh filter for reliable, low-maintenance operation.

Advantages

The pump combines a powerful 550 W motor with a two-stage hydraulic system to deliver up to 4700 litres per hour at high pressure. A robust inox stainless steel housing and pump shaft increase durability. An adjustable floating switch prevents dry running by switching the pump off at a preset water level. The aluminium telescopic pipe can be adjusted to position the outlet over the barrel rim without loss, and the slim design fits through 150 mm openings. The integrated fine mesh filter protects against blockages and is easy to clean, while a carry handle and removable telescopic pipe simplify transport and storage.

How to use

Place the pump into the water container or rain barrel ensuring the telescopic pipe outlet is positioned over the rim to avoid splashing. Adjust the telescopic pipe to the correct length and connect the discharge hose or appliance, such as an oscillating sprinkler. Set the float switch to the preferred start/stop water level; for near-complete emptying use the continuous-on setting if a 5 mm residual water height is acceptable. Switch on the pump and monitor the first operation to confirm correct positioning and leak-free connections. Clean the integrated fine mesh filter regularly to maintain flow and prevent blockages.
