Can this pump handle large debris?

For sure. This dirty water submersible pump can move water containing large solid particles up to 35 mm in diameter, thereby making it suitable for pumping out ponds, muddy water and deep sumps. The dirty water transfer pump can be completely or partially submersed in the water.

How does the float switch work?

The adjustable float switch lets you set the pump to run continuously, or switch on/off automatically at your chosen water level. This ensures the pump cannot dry run, saving energy costs and reducing wear and tear.

Is it suitable for garden watering?

Only for basic transfer tasks. The 0.5 Bar max. discharge pressure isn’t high enough to operate common sprinklers, but it works well for pumping away waste water, emptying drums, tanks and containers, or draining water butts.
