## Long description

The Kärcher SBP 3800 barrel pump is an efficient solution for garden irrigation, designed to replace manual watering cans. By utilizing harvested rainwater, this pump helps conserve drinking water while providing a convenient way to maintain your garden. The system includes a complete set of accessories, such as a 15-meter hose, a spray gun, and necessary couplings, allowing for immediate use upon setup. Its design features a flexible drum edge attachment that ensures a secure fit on various barrel sizes, along with an integrated switch for easy operation.
Advantages
This pump offers significant ergonomic benefits by eliminating the need to carry heavy watering cans, reducing physical strain during garden maintenance. The inclusion of a float switch provides automatic regulation based on water levels, which effectively prevents the motor from running dry and extends the lifespan of the unit. The adjustable drum edge fixation allows the pump to be customized to different barrel heights, ensuring stability and ease of use. Furthermore, the built-in pre-filter protects the internal components from debris, while the thermal protection system prevents the motor from overheating during extended operation.
Suitable for
Irrigation of garden beds and lawns using collected rainwater
Filling watering cans or containers from water barrels
General garden watering tasks where a portable pump is required
This pump is not designed for pumping drinking water, corrosive liquids, or food-grade substances. It is also not suitable for continuous industrial use or for handling water containing large debris, as the maximum particle size is limited to 1 millimeter.

How to use
To begin, attach the pump to the edge of your water barrel using the provided flexible mounting bracket. Connect the included hose and spray gun to the outlet. Ensure the float switch is positioned correctly so that it can rise and fall with the water level. Plug the power cable into a standard 230-240 V outlet. Once the pump is submerged and the connections are secure, use the integrated switch on the bracket to activate the flow. The pump will automatically stop if the water level drops too low, protecting the motor from damage.
What to consider before purchase
Ensure your water barrel has an accessible edge for the mounting bracket.
Verify that the power source is within reach of the 10-meter cable.
Check that the water source is free of large debris exceeding 1 mm.
Usage recommendations: Regularly clean the built-in filter at the pump foot to maintain optimal flow rates and prevent clogging. Always store the pump in a frost-free environment during winter months to prevent damage to the internal components.
