The 400W cellar drain pump will be very useful in the event of a flood problem, but not only, it also allows you to empty dirty water or clear water. depending on your needs, you can use it to empty a well or manhole.
The 400W cellar pump has the advantage of being an all-terrain pump, it can evacuate contaminated water, i.e. dirty or muddy on construction sites or in the event of flooding for example.
The cellar vacuum pump has an automatic triggering system that allows it to operate independently. It starts when the water level rises (40cm) and stops when the water level is low (30cm).
It is therefore equipped with a switch-type float which regulates it.
The pump must not run dry.
