POWERFUL PERFORMANCE: 1100W motor ensures high flow rate up to 20,000 L/H with 1-1/2" discharge hose horizontally. It can lift water to a maximum vertical height of 9 meters. This submersible pump is designed to handle dirty water containing solids smaller than 35 mm.

Float switch can also be disabled by attaching it on the side slot, then the pump works manually, it can drain water as low as possible (5 cm), and it will keep continuously running and will not turn off automatically, so remember to cut off the power immediately to prevent the motor becoming burned.
