Kärcher BP 1 Submersible Barrel Pump, 400 Watts, 3800 Litres per Hour, 11 Metres, Yellow

The KÄRCHER BP 1 submersible barrel pump is designed for garden watering directly from rain barrels and water butts. This mains-powered unit runs on standard 210–240 V electricity and draws 400 W during use. It transfers stored rainwater into an irrigation setup, removing the need for manual watering cans. The motor delivers a maximum flow rate of 3,800 l/h for a steady supply in outdoor applications. A peak delivery head of 11 m allows the pump to push water across varied garden elevations. Maximum operating pressure reaches 1.1 bar, sufficient for standard watering tasks. Designed for outdoor use, the unit functions reliably as a dedicated irrigation source.

The plastic housing keeps the weight at a manageable 4.2 kg. Built-in carrying handles make it easier to move the pump between water reservoirs. A 10 m H07RN-F power cable provides ample reach from a mains outlet to the installation point. Overload protection prevents motor damage during extended operation. An integrated water filter blocks debris from entering the mechanism and causing blockages. A direct on/off switch gives manual control over watering. An adjustable float switch regulates operation and automatically prevents dry running when the water level drops.

• IPX8 waterproof rating – allows the pump to be fully submerged for continuous, safe operation.
• Maximum immersion depth of 8 m – permits placement at the bottom of deep rain barrels or underground tanks.
• G1 connecting thread – provides standard compatibility with common garden hose adapters and irrigation fittings.
• Maximum particle size of 1 mm – restricts large debris to keep lines clear and prevent internal damage.
• Maximum input water temperature of 35 °C – safely handles sun-warmed rainwater during peak summer months.
• Maximum suction height of 7 m – supports drawing water efficiently even when the reservoir level is low.
